This book was released on 2002-06-06 with total page 479 pages. Available in PDF, EPUB and Kindle. Book excerpt: 623435-28b.gifVolume B covers the ecological significance of the interactions among clay minerals, organic matter and soil biota. Soil is a dynamic system in which soil minerals constantly interact with organic matter and microorganisms. Close association among abiotic and biotic entities governs several chemical and biogeochemical processes and affects bioavailability, speciation, toxicity, transformations and transport of xenobiotics and organics in soil environments. This book elaborates critical research and an integrated view on basic aspects of mineral weathering reactions; formation and surface reactivity of soil minerals with respect to nutrients and environmental pollutants; dynamics and transformation of metals, metalloids, and natural and anthropogenic organics; effects of soil colloids on microorganisms and immobilization and activity of enzymes, and metabolic processes, growth and ecology of microbes. It offers up-to-date information on the impact of such a processes on soil development, agricultural production, environmental protection, and ecosystem integrity.

This book was released on 2012-12-06 with total page 312 pages. Available in PDF, EPUB and Kindle. Book excerpt: The use of organic residues as a means of maintaining and increasing soil fertility is of long-standing. This tradition has been somewhat neglected since the introduc tion of mineral fertilizers at low cost. More and more farmers and scientists are now showing renewed interest in the proper and effective use of org~tnic residues, composts and other recycled organic additives. The role and function of organic amendments in modern agricultural systems have become topics of major interest in the scientific and agricultural communities. Research work on residue disposal has provided new concepts on the interaction between organic components and soils as well as new handling technologies (e. g. pelletizing of organic residues). The trend to conserve energy has led scientists to study the minimal tillage system, to find ways of replacing conventional inorganic fertilizers with natural organic prod ucts or microbial preparations, and to develop new composting methods. The drive to achieve higher yields in commercial greenhouse farming has led to a search for optimum substrates as growth media and for improved management techniques. This has led to the introduction of organic substitutes for peat, nota bly those originating from agricultural wastes. Another important aspect is the current interest in organic farming, where use of synthetic chemicals is avoided or prohibited. An increasing percentage of the population in highly developed countries is willing to pay premium prices for food produced on soils where inorganic fertilizers and other agricultural chemicals have not been used.

Download or read book Factors Affecting Phosphate Sorption by Soils and Minerals written by Sergio Jorge Volkweiss and published by . This book was released on 1973 with total page 316 pages. Available in PDF, EPUB and Kindle. Book excerpt: The objectives of this research were to study the P sorption characteristics of soils and the effects of pH and of cation type and concentration on P sorption by soils and minerals. In an attempt to characterize the nature and properties of P sorption sites of soils, P sorption isotherms in a 0.1 N NaC1 system were obtained for six limed and unlimed agricultural soils from Rio Grande do Sul, Brazil. The equilibration time was 48 hours and the concentration of P in the final solution varied from near zero to 20 ugP/ml. Langmuir plots (c/x vs c) of the data resulted in curvilinear and/or multi-straight line relationships suggesting the presence of 2 or more populations of sites with different affinities for P. An iterative multiple regression analysis computer program that assumes that each population of site follows the Langmuir equation was used to analyze the sorption data. Three populations of sites with different affinities for P were detected and the Langmuir constants, k (binding energy term) and b (sorption maximum) were estimated for each population of sites. The median and range for values of k (ml/ug P) and b (ugP/g) for the three populations of site were in decreasing order of affinity for P:K1 = 140, (40-2870) and b1=120 (8-370); K2=2.4, (0.63-10) and b2=174, (25-704); and K3 =0.095, (0.051-0.27) and b3=763 (131-1460). On the average, the total number of P sorption sites (total) was made up of 10% of sites with high affinity for P, 22% with moderate and 68% with low affinity ...

Available in PDF, EPUB and Kindle. Book excerpt: For more than 30 years, soil testing has been widely used as a basis for determining lime and fertilizer needs. Today, a number of procedures are used for determining everything from soil pH and lime requirement, to the level of extractable nutrient elements. And as the number of cropped fields being tested increases, more and more farmers and growers will come to rely on soil test results. But if soil testing is to be an effective means of evaluating the fertility status of soils, standardization of methodology is essential. No single test is appropriate for all soils. Soil Analysis Handbook of Reference Methods is a standard laboratory technique manual for the most commonly used soil analysis procedures. First published in 1974, this Handbook has changed over the years to reflect evolving needs. New test methods and modifications have been added, as well as new sections on nitrate, heavy metals, and quality assurance plans for agricultural testing laboratories. Compiled by the Soil and Plant Analysis Council, this latest edition of Soil Analysis Handbook of Reference Methods also addresses the major methods for managing plant nutrition currently in use in the United States and other parts of the world. For soil scientists, farmers, growers, or anyone with an interest in the environment, this reference will prove an invaluable guide to standard methods for soil testing well into the future. Features
