Alike all other hill dwellers of the world, shifting cultivation, commonly known as 'Jhum', is the traditional agronomic practice among the indigenous people of hilly tracts of Bangladesh. This age old cultivation system affects, mainly negatively, on soil environment and worsens the upland watershed health. For investigating this hypothesis, a study was conducted at three pair sites viz: Simina Para, Kark Mohajon Para and At- mile area of Sadar upazila under Khagarachari district to determine the effects of shifting cultivation on soil environment. Both soil physico-chemical properties and the biochemical and biological properties of soil microbes were studied. The differences in microbial population count and population composition may not be universal for all shifting cultivation sites; however, it explains the unavoidability in the variations of the biological and biochemical characteristics of soil microflora in shifting cultivated areas and emphasizes the necessity of taking this factor into consideration in management of soils in fellow lands after shifting cultivation.

It is well established that preemergence herbicide activity is influenced by soil type, and recommended rates for most soil-applied herbicides are adjusted to soil type. Current technology allows application rates to be adjusted on the go (VRA), adjusting the rate as soil type changes in a field. Most applicators offering this service base herbicide rates on soil organic matter content. However, several other factors influence herbicide activity, most importantly weed density and environment. This research is to determine which of these factors is most important in determining the optimum herbicide rate, and the economic benefit of VRA to the grower. The objective of this study is to determine the relative contribution of soil type, weed density and environmental factors on herbicide effectiveness.

Document from the year 2010 in the subject Geography / Earth Science - Geology, Mineralogy, Soil Science, Dresden Technical University (Institute of Soil Science and Site Ecology), course: -, language: English, abstract: Soil properties are not only influenced by geographical factors, such as parent material, location and latitude. Often differences in land uses (forest, rubber plantation, paddy field, bare land) are known to have specific effects on soil properties. In the context of the project Living Landscapes China (LILAC) these effects were evaluated and the characteristics of soil types under changing conditions in two transects (altitude and parent material in transect 1, land uses in transect 2) in the Naban River Watershed National Nature Reserve were classified. We used field investigations to classify the soil types, as well as laboratory analyses to quantify specific characteristics in samples, taken from the profiles. Soil physical (bulk density, water content, texture) and chemical parameters (total contents of carbon, nitrogen and macro nutrients, ECEC) were investigated. While differences in altitude did not seem to have profound influences on the soils, effects of land uses were pronounced especially in the first 10 to 20 cm of soil profiles. Soils under forests contain between 1.3 % - 2 % SOC and 0.15 % - 0.17 % TN in the Ah horizon. With contents of 1.2 % SOC and 0.11 % TN (Ah horizon) the profile under agricultural use (paddy rice) clearly contains less S...

Master's Thesis from the year 2007 in the subject Agrarian Studies, grade: Merit class, Natural Resources Institute - University of Greenwich at Medway (-), course: Plant Health and Protection, language: English, abstract: Although it is widely recognised that environmental problems such as soil degradation erosion and desertification threaten sustained agricultural production in many States of northern Nigeria including Adamawa, Bauchi, Borno, Gombe, Jigawa, Kaduna Kano, Katsina, Kebbi, Sokoto and Zamfara. Very little information is available about the current status of the potential impact of soil degradation and whether the situation is worsening in all the States of northern Nigeria. However, it is now clear that the major factor explaining the severity and spatial distribution of soil degradation such as erosion and desertification in northern Nigeria is associated with human impact such as deforestation and mismanagement of land resources. Other factors includes overgrazing, use of mechanized equipment, deforestation and lack of government concern to protect the environment in the region, but few studies have been made on applied issues related to the physical and chemical processes including erosion, runoff and leaching. These problems are widely considered as a serious problem to agricultural production and its environmental consequences will remain an important issue during the 21st century.

Dioxins are environmental pollutant and classified as highly toxic polychlorinated aromatic compounds (PCAs) group. The sources of their release into environment are identified such as from uncontrolled waste incineration, some metallurgical processes and many industrial activities. In our environment, dioxins may be found in soil, fly ash, sediment or even in food. Considering this, a novel thermal remediation technology, namely zone combustion process, of particulate or powder materials contaminated by dioxins are proposed. The process was developed to give an alternative technology for effective dioxin contaminated soil remediation with higher efficiency. Some phenomena related with remediation mechanism of zone combustion process were examined and verified experimentally. The analysis and discussion in the book should reveal understanding the effectiveness of process performance and the behavior of dioxins during remediation. The book will be of interest to industrialist, environmental and process engineer, engineering student and/or anyone who concern with their clean environment.

Soil can be defined as the space time continuum forming the upper part of the earth's crust. It is a natural body comprised of solid, liquid and gases that occur on the land surface. Joffe (1949) defined soil as a natural body differentiated into horizons of mineral and organic constituents usually unconsolidated of variable depth, which differs from the parent material below in morphology, physical properties and constitution, chemical properties and composition, and biological characteristics. Soil is one of the most fundamental resources for sustainability and survival. It is one of the most important assets to protect and pass on to future generations.Soil contamination due to anthropogenic and natural sources is increasing day by day because of increasing population, industrialization, and urbanization. Soil is the receptor of many contaminants from various sources. Contamination decreases the quality of the soil and adversely affects soil organisms.For this study, soil samples from thirteen locations contaminated from agricultural, industrial, and organic sources spread over the districts of Alappuzha and Kottayam in Kerala in the south west coast area of India were analyzed to study the changes in soil characteristics and its influence on soil microbial communities and their activities.

For sustainable management of forest vegetation in the area, geology, soil and biota are important factors. Scientific investigation may be helpful in improving and regenerating degraded hills by protection of slopes through raising vegetation suited to parent material and soil. Soils are considered to be our basic treasure. Man is dependent on soil and productive soil depends on man. Each of the different kinds of soils requires special management practice which changes from season to season. The knowledge of mineralogical behavior of soils at good natural sites and at degraded sites opens at possibilities of optimal management inputs to augment production of the biomass from good site as well as from degraded site after suitable amelioration. In the present intensified programme of raising large scale plantation, especially of fast growing species, the fertility potential depends largely on the mineralogical composition of the soil. The underlying parent material plays a vital role in determining the success or other-wise of the plantations especially over a number of rotations in a given year. This book provides in-depth knowledge to the managers, foresters and land users to have a thorough knowledge about the content and nature of minerals present in the soil in diagnosing the fertility status and other soil-plant-parent material relationship in forestry.

Trace elements occur naturally in soils and some are essential nutrients for plant growth as well as human and animal health. However, at elevated levels, all trace elements become potentially toxic. Anthropogenic input of trace elements into the natural environment therefore poses a range of ecological and health problems. As a result of their persistence and potential toxicity, trace elements continue to receive widespread scientific and legislative attention. Trace Elements in Soils reviews the latest research in the field, providing a comprehensive overview of the chemistry, analysis, fate and regulation of trace elements in soils, as well as remediation strategies for contaminated soil. The book is divided into four sections: • Basic principles, processes, sampling and analytical aspects: presents an overview including general soil chemistry, soil sampling, analysis, fractionation and speciation. • Long-term issues, impacts and predictive modelling: reviews major sources of metal inputs, the impact on soil ecology, trace element deficient soils and chemical speciation modelling. • Bioavailability, risk assessment and remediation: discusses bioavailability, regulatory limits and cleanup technology for contaminated soils including phytoremediation and trace element immobilization. • Characteristics and behaviour of individual elements Written as an authoritative guide for scientists working in soil science, geochemistry, environmental science and analytical chemistry, the book is also a valuable resource for professionals involved in land management, environmental planning, protection and regulation.

Soybean is an important crop in the world due to its supply of proteins and oil. In spite of its importance as a source of protein and oil, its production is way below potential. Declining soil fertility and high fertilizer costs are major limitations to crop production in developing countries due to reduction in farm sizes caused by increased human population. Reduced dependence on inorganic fertilizer nitrogen and adopting farming practices that favour more economically viable and environmentally prudent nitrogen fixation will benefit both agriculture and the environment. Biological materials may offer a solution in alleviating soil fertility problems and hence increase in crop production. Farm derived sources such as crop residue, compost, manure and household waste can be used by farmers in the management of soil fertility. Animal manure and compost are beneficial in soils because they can increase the water holding capacity and cation exchange capacity. This book assesses the effect of soil amendment with manure (poultry and farmyard) on the plant growth, nodulation and yield respectively as compared with inorganic fertilizer.

This work investigates the impacts of the effluents and other wastes of a Textile Mill on quality of soil and water in the surrounding areas. Some specific impacts on soil and water quality have been identified. For example, the soil was getting enriched with both ionic matter and hydrophobic organic matter, which had important consequences. The soil became enriched with the trace metals, As, Cd, Cr, Cu, Hg, Mn, Ni, Pb, and Zn. The quality of the drinking water in and around the textile mill did reflect the changes in the physico-chemical quality of the soil. The water was characterized by considerable presence of the cations, Ca, Mg, Na and K, being compensated by comparative presence of the anions, Cl, NO3 and SO4. The toxic organic contaminant, phenol, was present in some of the drinking water sources. The water was contaminated with Mn, Ni, and Pb, and also fluoride. The rice crop grown in the study area had accumulated appreciable amounts of metals in them as seen from the analysis of rice grains and husks. Significantly, the husks were seen to be richer in the metals than the grains with one or two exceptions.

Biofilms are predominant mode of life for microbes under natural conditions. The three-dimensional structure of the biofilm provides enhanced protection from physical, chemical and biological stress conditions to associated microbial communities. These complex and highly structured microbial communities play a vital role in maintaining the health of plants, soils and waters. Biofilm associated with plants may be pathogenic or beneficial based on the nature of their interactions. Pathogenic or undesirable biofilm requires control in many situations, including soil, plants, food and water. Written by leading experts from around the world, Biofilms in Plant and Soil Health provides an up-to-date review on various aspects of microbial biofilms, and suggests future and emerging trends in biofilms in plant and soil health. Issues are addressed in four sub areas: I) The fundamentals and significance of biofilm in plant and soil health, and the concept of mono and mixed biofilms by PGPR and fungal biofilms.

Master's Thesis from the year 2013 in the subject Biology - Botany, grade: 1, , language: English, abstract: The increase of metals pollution in soil is a worldwide problem that effects the health of humans and environment. The use of green technology such as phytoremediation is one the environmental friendly technique, in which plants and other microbes are used to reduce the level of metals contaminants in soil and lower its uptake towards plants tissues. Studies reported a number of cereal crops such as wheat and medicinal plants like alfalfa accumulate heavy metals in their tissues at higher concentrations. In the present study, we investigated the effect of arbuscular mycorrhizal fungi (AMF) on wheat and alfalfa plants with the increase of zinc (Zn) and cadmium (Cd) concentrations in soil. After eight weeks of pot experiment, roots colonization, shoot and root biomass, growth, heavy metals contents and other biochemical parameters were assessed. The results indicated mycorrhizal inoculated (M) plants performed better at moderate Zn and Cd concentrations. In addition, higher phosphorus contents were observed in M treated plants as compared to NM plants. Results indicated that AMF inoculum exhibit different tolerance strategies to reduce metals toxicity in host plants. The effective mycorrhizal symbiosis was observed with wheat and alfalfa plants and can be useful for phytostabilization of metals contaminated soils which can play a vital role in increase of plants prod...

High concentration of chemicals and toxic metals made the soil incapable for any intended engineering works. studies have been performed on contaminated soil and for their stabilization.In this work attempt has been made to study the effect of diesel oil on properties of local soil and then their stabilization with Fly Ash (FA) and Cement Kiln Dust (CKD). The stabilisation of contaminated soil by CKD improved the soil characteristics to some extent. The value of cohesion can be increased nearly linear by addition of CKD. Swelling is reduced by increasing amount of CKD which leads to the conclusion that the swelling behavior of the soil can be effectively controlled by the addition of CKD. From this study, the CKD may be effectively utilized in improvement of hydrocarbon contaminated soil. The stabilisation of contaminated soil by fly ash improved the soil characteristics to some extent. From the overall observations of the study that, the stabilisation of diesel engine oil contaminated soil using fly ash has been observed to be effective.

Forest soils are the foundation of the entire forest ecosystem and complex, long-term interactions between trees, soil animals, and the microbial community shape soils in was that are very distinct from agricultural soils. The composition, structure, and processes in forest soils at any given time reflect current conditions, as well as the legacies of decades (and even millennia) of interactions that shape each forest soil. Reciprocal interactions are fundamental; vegetation alters soil physical properties, which influence soil biology and chemistry, which in turn influence the growth and success of plants. These dynamic systems may be strongly influenced by intentional and unintentional management, ranging from fire to fertilization. Sustaining the long-term fertility of forest soils depends on insights about a diverse array of soil features and changes over space and time. Since the third edition of this successful book many new interests in forest soils and their management have arisen, including the role of forest soils in sequestering carbon, and how management influences rates of carbon accumulation. This edition also expands the consideration of how soils are sampled and characterized, and how tree species differ in their influence on soil development. Clearly structured throughout, the book opens with the origins of forest soil science and ends with the application of soil science principles to land management. This new edition provides: A completely revised and updated Fourth Edition of this classic textbook in the field A coherent overview of the major issues surrounding the ecology and management of forest soils Global in scope with coverage of soil types ranging from the tropical rainforest soils of Latin America to the boreal forest soils of Siberia New chapters on Management: Carbon sequestration; Evidence-based approaches and applications of geostatistics, GIS and taxonomies A clear overview of each topic, informative examples/case studies, and an overall context for helping readers think clearly about forest soils An introduction to the literature of forest soil science and to the philosophy of forest soil science research This coherent overview of the major issues surrounding the ecology and management of forest soils will be particularly useful to students taking courses in soil science, forestry, agronomy, ecology, natural resource management, environmental management and conservation, as well as professionals in forestry dealing with the productivity of forests and functioning of watersheds.

Estimates indicate that a majority of the earth's land has been seriously degraded. One of the key degradation problems is poor soil health, which has been identified as a key constraint in agricultural productivity and reducing rural poverty in many parts of the tropics, particularly in Sub-Saharan Africa. Ethiopia's economy is primarily based on agriculture. However, this sector is increasingly being confronted with a rapidly growing population, and this has resulted in land use/cover changes. The changes in land use disturbs ecosystem balance and lead to a significant change in the physical, chemical, and biological soil health thereby yield declines. Half of the Ethiopian highland arable lands are moderately to severely degrade. Tigray, the Northern region of Ethiopia, suffers from extreme land degradation and soil health deterioration. Agulae catchment, the study area which is found in Eastern Tigray also has similar problems. Since previous studies on factors affecting soil health depletion has not been made at a catchment level, this study was conducted to fill the existing knowledge gap on the effects of and use change on soil health and its implication on soil management.

Edward H. Faulkner startled the agricultural world—all of it, on six continents—when he published Plowman’s Folly in 1943. As almost everyone knows, he launched a vigorous attack on the plow and dseveloped in a masterful way the advantages of surface incorporation of organic material. The Readers Digest summed up American interest at the time in the statement, “Probably no book on an agricultural subject has ever prompted so much discussion in this country.”A Second Look is a sequel to Plowman’s Folly. In it Mr. Faulkner answers his critics and re-examines the theories expressed earlier, in the light of extensive investigations he subsequently made in visiting experiment stations, soil scientists, and farmers in many parts of the country. Finally, in simple, straightforward language, he gives the lie to “soil impoverishment.” Highly condensed, here is his thought: The soil which the gardener or farmer works is made up of tiny crystalline fragments. The action of soil acids, principally those released through the decay of organic matter, unlocks the minerals required for healthy plant growth.If this is true, then the indiscriminate and continuous use of commercial fertilizer is a mistake. In fact, says Mr. Faulkner, the “bank account” theory of soil is bankrupt. It holds that whatever we take from the soil in the growing of crops must be put back—usually in the form of prepared fertilizers. What the soil needs, on the contrary, is the gentle chemistry described above. If a man...

Soil efflux (SEF) is an important component in the global carbon cycle. The combination of root and microbial respiration, SEF is often used as a measure of biological productivity in the soil. Although SEF has been widely studied, some areas have been neglected, including the effect of timber harvest management on SEF and SEF in different soil horizons. Timber harvesting compacts the soil, removes standing vegetation, increases debris, alters the microclimate, etc., all of which could potentially alter SEF. The Missouri Ozark Forest Ecosystem Project (MOFEP) is a long-term study in which the Missouri Department of Conservation (MDC) installed experiments of single-tree uneven-age (UAM), clear-cut even-age (EAM), and control no-cut (NHM) timber harvests to find ecosystem-management alternatives. To determine the effect of timber harvest on subsurface SEF, nine soil pits, three in each treatment, were dug to directly measure the magnitude of changes in SEF across the soil profile.

Maize is the main staple crop in East African mountains but its yield is affected by biotic and abiotic factors. Lepidopteran pests such as, Chilo partellus (Crambidae) and Busseola fusca (Noctuidae) reduced maize yield while soil elements increase the yield. In addition to enhancing maize yields, some soil element such as silicon (Si) aid plants in overcoming abiotic and biotic stresses. Hence, any factor that induces Si deficiency in soil might be detrimental to the plant growth and its resistance to insect pests and diseases. Understanding how the projected temperature increase will affect Si levels in soil and maize is crucial in promoting maize production in different agro-ecosystems in the face of climate change. This study evaluated the Si levels in both soil and maize plants cultivated along three altitudinal gradients of East African mountains (Machakos, Taita and Kilimanjaro) characterized by graded changes in climatic conditions. The study also linked the Si level in maize plants to lepidopteran pests' distribution.

In contrast to the classical books which largely focus on separate, individual physicochemical and biological aspects, this book aims to integrate the frontiers of knowledge on the fundamentals and the impact of physicochemical and biological interactions and processes of AOCs in soil, sediment, water and air. The specific objectives of this book are to address: (1) fundamental biophysico-chemical processes of AOCs in the environment, (2) occurrence and distribution of AOCs in air, water, and soil, and their global cycling, (3) the state-of-the-art analytical techniques of AOCs, and (4) restoration of natural environments contaminated by AOCs. The book also identifies the gaps in knowledge on the subject matter and as such provides future directions to stimulate scientific research to advance the chemical science on biophysico-chemical interfacial reactions in natural habitats. By virtue of complex nature of the interactions of AOCs with different environmental components and matrixes, no single available technique and instrument is satisfactory yet for determining their fate, transport, availability, and risk in the environment. In order to fully understand the biophysico-chemical interactions and processes of AOCs in the environment, it is critical to know chemical, physical and biological properties of AOCs and their analytical techniques. The book is unique because of its multidisciplinary approach as it provides a comprehensive and integrated coverage of biophysico-chemical reactions and processes of AOCs in various environments, associated analytical techniques, and restoration of natural environments contaminated by AOCs.

Many hill slope areas are vulnerable to soil erosion and shallow slope failures due to intense and frequent rainfall of tropical climate.In this study, Laboratory tests were performed on natural soil and soil mixed with deferent percentage of lime to improve soil properties and resistance against slope failure.When lime mixed with in-situ soil, it reduces swelling potential and shrinkage hence inhibit formation of cracks and also reduce soil's dispersibility therefore, reduce erosion possibility. Soil mixed with lime has lower permeability thus, it enhances capillary barrier effects and limits rainfall infiltration into the soil.Results show that optimum lime content to be used in the mix design is 7% by dry unit weight of soil. A two dimensional finite element model of slope was used to evaluate performance of the optimum lime-soil mixed as capillary barrier. The analysis revealed that the optimum thickness of slope cover system in capillary barrier is 30cm. Finding of this study, would contribute to a practical method of slope stabilisation and to display optimum slope cover thickness in capillary barrier effects.

Master's Thesis from the year 2018 in the subject Engineering - Geotechnology, grade: 9.36, National Institute of Technology, Rourkela, language: English, abstract: Construction of building on clay soil is highly risky due to its poor strength. Clayey soil creates many problems to the Geotechnical Engineers primarily because of repeated change of moisture content. Normally, these soils increase in size and swell when they absorb water and reduce in size and shrink when they become dry. Volume change in soil leads to distortions in the form of settlement due to contraction as a result of dryness or in the form of expansion due to swelling as a result of the absorption of water. There may be the need for soil treatment to improve the engineering properties of such soil. Compacted bentonite is often used as a buffer materials and for radioactive waste disposal system. A good understanding of the hydro-mechanical behavior of clay soil is essential to ensure safe disposal.The present study reports the results on the effects of temperature on swelling pressure and compressibility characteristics of soil. In this study, two different type of soils were used. One of them was a bentonite (liquid limit = 139%) procured from Bikaner, Rajasthan another one was Rourkela local soil (liquid limit = 35%). A new oedometer was designed and developed in-house to carry out consolidation and swelling pressure tests at a higher temperature. Swelling pressures tests on compacted bentonite speci...

Now a day the soil fertility of high land areas, where most of the agricultural activities have been done at the escarpments of the landscape, has been decreased. These in turn decrease the productivity of land because of the removal of soil and nutrient by erosion. Therefore the use of fertilizer has increased to compensate the removed nutrients through erosion. The change in land use is also another factor to increase or decrease the fertility of the land. The application of the same fertilizer rate at each landscape position lead us wastage or inefficient. This book, therefore, provides the variability of soil chemical fertility among different land use and landscape position, as well as soil deterioration indices. The analysis help some light on this variability, and especially useful to professionals like researchers, agriculture experts and instructors etc working in areas of soil fertility and decision makers who may use fertilizer in the high land areas or any else.

Groundnut (Arachis hypogaea L.) also known as peanut and earthnut, is an important oilseed crop largely grown by resource poor smallholder farmers under rainfed conditions. These farmers employ different tillage practices in the production of the crop. Many farmers perform tillage operations without being aware of the effect of these operations on soil physical properties and crop responses. It is carried out mainly to loosen the upper layer of soil, to mix the soil with fertilizer and organic residues, to control weeds, and to create a suitable seedbed for germination and plant growth. The theme of nutrient management in integrated way for increasing the soil fertility is gaining ground throughout the world in recent years due to high cost of fertilizer and reduced availability of organic manures. Modern tillage and integrated nutrient management practices may affect soil fertility and productivity of groundnut due to different soil conditions created and fulfills the nutrient requirement of crop. The book contains the information on the effect of tillage and integrated nutrient management practices on soil fertility and productivity of groundnut under rainfed conditions.

This book addresses the latest issues in multiscale geomechanics. Written by leading experts in the field as a tribute to Jean Biarez (1927-2006), it can be of great use and interest to researchers and engineers alike. A brief introduction describes how a major school of soil mechanics came into being through the exemplary teaching by one man. Biarez's life-long work consisted of explaining the elementary mechanisms governing soil constituents in order to enhance understanding of the underlying scientific laws which control the behavior of constructible sites and to incorporate these scientific advancements into engineering practices. He innovated a multiscale approach of passing from the discontinuous medium formed by individual grains to an equivalent continuous medium. The first part of the book examines the behavior of soils at the level of their different constituents and at the level of their interaction. Behavior is then treated at the scale of the soil sample. The second part deals with soil mechanics from the vantage point of the construction project. It highlights Biarez's insightful adoption of the Finite Element Codes and illustrates, through numerous construction examples, his methodology and approach based on the general framework he constructed for soil behavior, constantly enriched by comparing in situ measurements with calculated responses of geostructures.

Soil erosion has been one of the major problems undermining agricultural production in Ethiopia. Consequently, efforts are being made by the government to tackle the adverse effect of soil erosion via Food-for-Work and Cash-for-Work programs. However, the existing literature shows that the achievements of such programs are far from the expectations. Does such an experience mean that there is no hope for soil conservation practices in Ethiopia? Absolutely it is doubtful, the problem could have been rather, the campaigns that have been undertaken in Ethiopia for soil conservation practices have failed to consider local peoples' willingness to pay for such projects from the very initiation of conservation measures. This motivates that, adequate understanding of the socio economic circumstances is required to determine the household's soil conservation demand behavior and the factors that determine their willingness to pay for it. Hence, this book explores the value that the rural households have attached to soil conservation measure using the non marketed valuation technique called Contingent valuation method.

The Art of War is one of the oldest and most successful books on military strategy in the world. It has had a huge influence on Eastern military thinking, business tactics, and beyond. Sun Tzu recognized the importance of positioning in strategy and that position is affected both by objective conditions in the physical environment and the subjective opinions of competitive actors in that environment. He taught that strategy was not planning in the sense of working through a to-do list, but rather that it requires quick and appropriate responses to changing conditions. Planning works in a controlled environment, but in a competitive environment, competing plans collide, creating unexpected situations. The Art of War has also been applied to business and managerial strategies.

When waste is deposited at dumpsites it is usually forgotten yet it continues to interact with environmental factors to become even more dangerous to both people and the environment through soil, water and air pollution. This may cause ecological damage resulting in the ecosystem failing to sustain both animal and plant life. People may also contract diseases from polluted environmental media through contaminated food, air or water. In this study the aim was to evaluate the role of environmental factors in the distribution of pollutants around Gweru dumpsite. The study compared the concentration levels of lead (Pb), cadmium (cd) and sulphides (SO2) around the dumpsite with the natural concentration levels of the same chemicals in the surrounding areas. It also determined whether there is a significant (p>0.05) relationship between the concentration levels of pb, cd and sulphides and environmental factors specifically slope, soil bulk density, flow direction, soil infiltration rate and distance around the dumpsite.Results of the study established that there is a significant (p>0.05) difference between the concentration levels of each of the chemicals within and around the dumpsite.

Facsimile of 1940 Edition. An Agricultural Testament is Sir Albert Howard's best-known publication and remains one of the seminal works in the history of organic farming movement. The work focuses on the nature and management of soil fertility, and notably explores composting. At a time when modern, chemical-based industrialized agriculture was just beginning to radically alter food production, it advocated natural processes rather than man-made inputs as the superior approach to farming. It was first published in England in 1940. Since this book first appeared in 1940, it has been regarded as one of the most important contributions to the solution of soil rehabilitation problems ever published. More importantly, it is regarded as the keystone of the organic movement.Louis Bromfield called it "the best book I know on soil and the processes which take part in it." Soil Science called it "the most interesting and suggestive book on soil fertility which has appeared since King's Farmers of Forty Centuries." And Mother Earth News recently called it "the most basic of all introductions to organic farming by the founder of the modern movement."The object of the book was to draw attention to the loss of soil fertility, brought about by the vast increase in crop and animal production, that has led to such disastrous consequences as a general unbalancing of farming practices, an increase in plant and animal diseases and the loss of soil by erosion.

Leguminous tree species such as Acacia could be good candidates to grow in soils very deficient in nitrogen because of their associated rhizobial symbioses constitute a source of N input to the ecosystem. This nitrogen is returned to the soil by the natural loss of leaves which improves the soil fertility and its physical properties through maintenance of soil organic matter, or soil aggregation. In addition, they provide high- quality animal fodder, timber, fuel wood, charcoal, gums and other products. In addition, Acacias are keystone species as they improve soil conditions under their canopies. Plant species diversity and occurrence beneath the tree canopies is higher than in the surrounding areas. It is very old genus; some reports provide evidence for its presence in the Eastpans (Abu Ballas) as well as in the Hidden valley depression (Farafra oasis) and were aged between 6700 and 6200 years before present. Therefore, the objectives of this study were to evaluate the effect of different fertilizers and growing media on growth and chemical composition of Acacias in Africa.

Scientific Study from the year 2016 in the subject Agrarian Studies, , language: English, abstract: Jackfruit (Artocarpus heterophyllus) is commonly grown in home gardens of tropical and sub-tropical countries. The fruit contains high levels of carbohydrates, protein, starch, calcium and vitamins. The Artocarpus heterophyllus is believed indigenous to the Western Ghats of India. It is adapted only to the humid tropical and near tropical climate. The tree flourishes in rich deep soil of medium or open texture, sometimes on deep gravelly or laterite soil. In India they say that the tree grows tall and thin on sand, short thick on sandy land. Here the physical and chemical properties of soil from surrounding plots of different varieties of Arthocarpus heterophyllus have been analysed by using different technical methods and evaluating the effects of soil property on jackfruit nutritional quality. It was observed that there was a considerable difference in case of some minerals likes phosphorous, potassium, magnesium, zinc and manganese. Change in the soil pH also noticed. The pH also plays a major role in the sweetness of the jackfruit. The optimum pH of the amylase inside the jackfruit was found to be 6.2 to 6.8. The result shows that the soils that have higher pH have more sweet flakes. Proximate nutritional composition of the flake reveals the presence of protein, fat and fibre in a greater amount in some flake and these flakes were sweeter than the others. There was a much d...

Mining activities significantly impact the environment; they generate huge quantities of spoil, promote deforestation and the loss of agricultural production, as well as releasing contaminants that result in the loss of valuable soil resources. These negative impacts are now being recognized and this book shows how corrective action can be taken. The introduction of sustainable mining requires mitigation strategies that start during the mine planning stage and extend to after mineral extraction has ceased, and post-closure activities are being executed. Reclamation of Mine-impacted Land for Ecosystem Recovery covers: methods of rejuvenation of mine wasteland including different practices of physical, chemical and ecological engineering methods; benefits of rejuvenation: stabilization of land surfaces; pollution control; aesthetic improvement; general amenity; plant productivity; and carbon sequestration as well as restoring biodiversity and ecosystem function; best management practices and feasible solutions to the impacts of mining which will reduce the pollution load by reducing the discharge rate and the pollutant concentration; reduce erosion and sedimentation problems, and result in improved abandoned mine lands; and ecosystem development. The authors explain how mining impacts on soil properties and how soil carbon reserves/soil fertility can be restored when mining has ceased. Restoration involves a coordinated approach that recognizes the importance of key soil properties to enable re-vegetation to take place rapidly and ecosystems to be established in a low cost and sustainable way. This book’s unique combination of the methods for reclamation technologies with policies and best practice worldwide will provide the background and the guidance needed by scientists, researchers and engineers engaged in land reclamation, as well as by industry managers.

This book presents an in-depth guide to the subject matter and main points of hydrostructural pedology, as theorized for the first time. The authors focus on the underlying concepts, the purpose and role this field plays within agroenvironmental sciences. It is divided into two parts. Part 1 presents the theory behind hydrostructural pedology. The systemic approach applied to the soil is presented, showing how this leads to the thermodynamic formulation of water in the soil’s organized medium and to the systemic modeling of soil–water-coupling in natural or anthropic organizations. Part 2 presents the methodology to complement the first part. In it, the authors determine the hydrostructural characteristics of the pedostructure, characteristic parameters of equilibrium state equations and the hydrostructural functioning of the soil.

The study aimed at estimating runoff and sediment yield by using remote sensing and GIS techniques in catchment. Thematic layers of soil, topographic elevation, slope, land use/land cover (LULC) were generated in GIS platform by using existing soil map, SRTM DEM, and IRS-P4 satellite imagery. The GIS-based soil map was used to develop hydrologic soil group (HSG) map of the study area. HSG and LULC maps were used to generate curve number (CN) map in the GIS environment. Weighted CN value under antecedent moisture condition (AMC) type I, II and III for catchment was computed based on the GIS-based CN map, which were used to compute annual surface runoff. Furthermore, GIS-based maps of six USLE model factors, R, K, L, S, C and P, were generated. Raster maps of the six USLE factors were multiplied to estimate sediment yield on pixel basis.

Forest soils are the foundation of the entire forest ecosystem and complex, long-term interactions between trees, soil animals, and the microbial community shape soils in was that are very distinct from agricultural soils. The composition, structure, and processes in forest soils at any given time reflect current conditions, as well as the legacies of decades (and even millennia) of interactions that shape each forest soil. Reciprocal interactions are fundamental; vegetation alters soil physical properties, which influence soil biology and chemistry, which in turn influence the growth and success of plants. These dynamic systems may be strongly influenced by intentional and unintentional management, ranging from fire to fertilization. Sustaining the long-term fertility of forest soils depends on insights about a diverse array of soil features and changes over space and time. Since the third edition of this successful book many new interests in forest soils and their management have arisen, including the role of forest soils in sequestering carbon, and how management influences rates of carbon accumulation. This edition also expands the consideration of how soils are sampled and characterized, and how tree species differ in their influence on soil development. Clearly structured throughout, the book opens with the origins of forest soil science and ends with the application of soil science principles to land management. This new edition provides: A completely revised and updated Fourth Edition of this classic textbook in the field A coherent overview of the major issues surrounding the ecology and management of forest soils Global in scope with coverage of soil types ranging from the tropical rainforest soils of Latin America to the boreal forest soils of Siberia New chapters on Management: Carbon sequestration; Evidence-based approaches and applications of geostatistics, GIS and taxonomies A clear overview of each topic, informative examples/case studies, and an overall context for helping readers think clearly about forest soils An introduction to the literature of forest soil science and to the philosophy of forest soil science research This coherent overview of the major issues surrounding the ecology and management of forest soils will be particularly useful to students taking courses in soil science, forestry, agronomy, ecology, natural resource management, environmental management and conservation, as well as professionals in forestry dealing with the productivity of forests and functioning of watersheds.
