Available in PDF, EPUB and Kindle. Book excerpt: About 20 years ago the emphasis in soil chemistry research switched from studies of problems related to scarcities of plant nutrients to those arising from soil pollutants. The new problems have come about because of the excessive uses of fertilizers, the inputs from farm and industrial wastes, the widespread applications of anthropogenie xenobiotic chemicals, and the deterioration of soil structure resulting from certain modern agriculture practises. The International Society of Soil Science (ISSS) recognized these problems and challenges. A provisional Working Group was set up in 1978 to focus attention on soil colloids with a view to understanding better the interactions wh ich take place at their surfaces. It was recognized that these interactions are fundamental to problems of soil fertility, as weIl as to those of soil pollution. After the group had received the official support of ISSS at its 12th International Congress in New Delhi in 1982 it set as its priority the assembling and evaluation of information, relevant to the soil and environmental sciences, concerning the composition and structure of soil colloids. Prior to that aseries of Position Papers were published in the Bulletin of the International Society of Soil Science (Vol. 61, 1981) outlining the state of knowledge about the composition and properties of soil colloids.

This book was released on 2013-11-21 with total page 598 pages. Available in PDF, EPUB and Kindle. Book excerpt: S. Henin Versailles, France It was a pleasure for me to take part in the NATO Advanced Study Workshop for studies of 'Soil Colloids and their Associations in Soil Aggregates'. The meeting provided me with a welcome opportunity to renew acquaintances with respected colleagues in the various fields of Soil Science, to listen to their presentations, and be involved in discussions which were at the frontiers of the science which deals with the structures and the associations of the soil colloidal constituents. In my view the rapid advances in Soil Science, and the great benefits to agriculture from these, have their origins in the emerging understanding of the structures and the associations of the different soil colloids. It is clear that much research is still needed before the molecular details of the most important of the structures and of the interactions are fully understood. The associations between the soil colloids, and the manner in which they bind to or hold the other constituents of soils in aggregates is fundamental to soil fertility. and the Modem intensive agriculture leads to the degradation of soil structure subsequent loss through erosion of a resource that is vital for the production of food. This degradation is considered to result primarily from the biological oxidation of the indigenous soil organic matter, and from the failure to return to the soil sufficient organic residues to compensate for such losses.

Available in PDF, EPUB and Kindle. Book excerpt: Since the beginning of this century production of chemical fertilizers has increased many fold, and the production of pesticides for addition to the soil has become a new major industry. These are not the only chemicals added to the soil, because by accident or design many other chemicals which enter the environment end up in the soil. The soil has to produce the bulk of the food and fiber to sustain this growing population. In this volume a short historical outline of the development of soil science is given, touching briefly on soil formation, soil physics, and soil biology, as it can be misleading to regard soils simply as chemical entities. It is also important to have some appreciation of the several processes which have produced the particular soil found at any one place. The major soil types of the world differ according to their origin. Several systems exist for classifying them, and different names are in use for the same major soil types. The most common names of these are therefore introduced. The following two chapters deal with the inorganic and organic components of soils respectively. The chemical structures of the major inorganic components are now reasonably well known, but this is not true of the organic (or humic) materials in soils. The relevant chapter presents an account of what has been experimentally established regarding the constitution of the peculiarly intractable complex of organic compounds found in soils. Chemical processes in soils are largely determined by reactions at the surfaces of the soil colloids. The final three chapters are therefore concerned with the nature and extent of the surfaces of soil colloids, their electrical characteristics, and the ways in which ions and water are held and arranged at the surfaces.
