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.

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.

Incorporating manures of plant and animal oringin into soil is known to improve soil nutrient content while enhancing soil aggregate stability and microbial activity. The practice of mulching the soil with materials like grass, leaves and food processing wastes conserves soil moisture, regulates soil temperature and prevents surface erosion. In addition to these traditional roles, organic materials can also be successfully used in cleaning up contaminated soil and water. Many countries are subjected to land contamination from past and present industrial activities. Thus, soil remediation through sustainable, inexpensive and environment-friendly techniques remains a global challenge. In this book, the effectiveness of organic materials in metal immobilization is evaluated through sorption studies, microbial respiration and plant uptake in order to determine their potential for the remediation of contaminated soil.

The Sermon on the Mount contains many comparisons. In this book, the functions of these comparisons are studied by the methodology called comparative characterization. Characterization is the way a character is characterized in a narrative. Comparative characterization is the characterization of a character using comparisons. In comparative characterization, another character is used as a foil to bring out a characteristic trait of a concerned character. Jesus characterized the ideal disciple in the Sermon on the Mount with many descriptions and imperatives. To characterize the ideal disciple Jesus used many comparisons and highlighted the characteristic features that embody the ideal disciple.The many comparisons used in the Sermon on the Mount are identified in this study through comparative characterization. In addition, the teleological purpose of the comparisons, which is to play as foil to the characterization of the ideal disciple, is identified and highlighted. Thus, this study identifies Jesus' characterization of the ideal disciple and his complex portrayal of the ideal disciple with the many uses of comparisons in the descriptions and imperatives of Jesus in the Sermon on the Mount.""Bennet Arren Lawrence uses literary, narrative, and comparative characterization methods at their best in his analysis of the Sermon on the Mount.

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.

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...

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...

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.

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.

Edward H. Faulkner A Second Look

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...

Scientific Study from the year 2017 in the subject Biology - Micro- and Molecular Biology, grade: 1.5, Mar Augusthinose College, language: English, abstract: The dyes are complex chemical compounds that imparts colour to substances. On the urge of urbanisation, the use of synthetic dyes is increasing largely and its untreated effluent release causes serious environmental pollution affecting water bodies by disturbing the aquatic ecosystem, soil, plants, animals, humans. The recalcitrant nature of these dyes limits its treatment using conventional methods wherein biological methods using microorganisms are reported to completely mineralize the dyes lowering the release of degradation products. The present work focuses on the biodegradation of synthetic dyes by isolating bacteria from a dyeing unit. Soil samples from the dye contaminated soils was collected, its degradation potentiality was observed using three major dye of studies congo red, brilliant green and methylene blue within 24 hr incubation. Maximum decoloarized dye (congo red and brilliant green) were chosen, serially diluted to 10-5 and plated to obtain two distinct colonies from decolorized congo red (CR1, CR2) and three distinct colonies from decolorized brilliant green (BG1, BG2, BG3). These isolates were biochemically characterized. Molecular characterization was performed by isolating DNA from five isolates and amplified it using PCR, with the 16s rRNA gene primer.

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.

The soil loss is proportional to degree of slope and accordingly different models have been developed. But most of them consider uniform slope and in nature the slopes are combination of simple profiles. The undulating slope shape will have different effect on runoff, soil loss and thus the nutrient loss. Therefore this study was undertaken with the objectives (i) to study the effect of undulating slopes on runoff and soil loss (ii) to study the effect of slope shape on nutrient movement and loss and (iii) determine the topographic factor in Universal Soil Loss Equation for Undulating slopes. The runoff and soil loss was maximum from the concave-convex-concave- convex slope shape without crop, whereas it was minimum from uniform slope without crop.

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...

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.

Soil contamination included oil, chemical, heavy metals and organic contaminant. 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.

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.

Soil erosion is a major threat to the sustainability of agricultural land and food security. Thus, this book tries to contribute to the adoption of soil conservation that improves agricultural productivity in the underdeveloped world. To study the status of soil conservation practices in the study area, four sample kebeles (sub-districts) were randomly selected. About 121 sample farmers were randomly selected from the selected kebeles as respondents. The respondent farmers were categorized as adopters and non adopters of soil conservation practices. Primary and secondary data were collected. The result showed that educational level, slope of farmland, plot distance, livestock holding, off-farm activities, land tenure security system, training, extension support, perception of farmers` about soil erosion as a problem, and their attitude to conservation technologies were found to be significant in influencing farmers` adoption of soil conservation practices. The book could be useful to professional researchers, development agents, soil conservation experts in the governmental and non-governmental organizations.

Document from the year 2011 in the subject Agrarian Studies, University of Greenwich, language: English, abstract: It is widely recognised that environmental problems such as soil degradation (erosion and desertification) affects many agricultural lands globally. These problems have caused soil quality decline, crop yield reduction, economic crisis, poverty, unemployment, and rural urban migration. Soil management practices are considered as the most vital and sustainable possible solution to control soil erosion and desertification. This management include use of organic manure, crop rotation, use of cover crop, intercropping, planting shelter belt and afforestation, provision of water ways, good surface drainage system, restoration of rangeland, regeneration and secondary forest, and political changes.

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.

Chromium exists in nature as complexes of two stable oxidation states – trivalent chromium(III) and hexavalent chromium(VI). Although trivalent chromium is required in trace amounts for sugar and lipid metabolism in humans and its deficiency may cause a disease called chromium deficiency; hexavalent chromium is toxic and carcinogenic. As chromium compounds were used in dyes and paints and the tanning of leather, these compounds are often found in soil and groundwater at abandoned industrial sites, now needing environmental cleanup and remediation. The Bioinorganic Chemistry of Chromium: From Biochemistry to Environmental Toxicology takes a critical look at what the biochemical data indicate about chromium's role in the body and the biological mechanisms of its toxicology. Topics covered include: What do we know about the biochemical roles and mechanisms of chromium? Is chromium an essential element in the mammalian diet? Is chromium(III) effective as a nutraceutical, a therapeutic agent, and as a supplement in animal feed? What is the biochemistry behind the toxicology of chromium(III) and chromium(VI):the mechanisms of metabolism, genetic and epigenetic effects, and disruption of cell signalling? What are the current chromium(VI) policies and positions from regulatory agencies? The Bioinorganic Chemistry of Chromium: From Biochemistry to Environmental Toxicology is an important contribution to the bioinorganic and trace element biochemical fields which will find a place on the bookshelves of bioinorganic chemists, biochemists, inorganic chemists, toxicologists, nutritionists and regulatory affairs professionals.

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.
