The Role of Organic Matter in Modern Agriculture by Y. Chen,Y. Avnimelech Pdf

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.

The Importance of Soil Organic Matter by Alexandra Bot,José Benites Pdf

Soil organic matter - the product of on-site biological decomposition - affects the chemical and physical properties of the soil and its overall health. Its composition and breakdown rate affect: the soil structure and porosity; the water infiltration rate and moisture holding capacity of soils; the diversity and biological activity of soil organisms; and plant nutrient availability. This document concentrates on the organic matter dynamics of cropping soils and discusses the circumstances that deplete organic matter and their negative outcomes. It then moves on to more proactive solutions. It reviews a "basket" of practices in order to show how they can increase organic matter content and discusses the land and cropping benefits that then accrue.--Publisher's description.

Soil Organic Matter in Sustainable Agriculture by Fred Magdoff,Ray R. Weil Pdf

Recognition of the importance of soil organic matter (SOM) in soil health and quality is a major part of fostering a holistic, preventive approach to agricultural management. Students in agronomy, horticulture, and soil science need a textbook that emphasizes strategies for using SOM management in the prevention of chemical, biological, and physical problems. Soil Organic Matter in Sustainable Agriculture gathers key scientific reviews concerning issues that are critical for successful SOM management. This textbook contains evaluations of the types of organic soil constituents—organisms, fresh residues, and well-decomposed substances. It explores the beneficial effects of organic matter on soil and the various practices that enhance SOM. Chapters include an examination of the results of crop management practices on soil organisms, organic matter gains and losses, the significance of various SOM fractions, and the contributions of fungi and earthworms to soil quality and crop growth. Emphasizing the prevention of imbalances that lead to soil and crop problems, the text also explores the development of soils suppressive to plant diseases and pests, and relates SOM management to the supply of nutrients to crops. This book provides the essential scientific background and poses the challenging questions that students need to better understand SOM and develop improved soil and crop management systems.

Sustainable Soils by Benjamin Wolf,George Snyder Pdf

Find the right balance of organic matter, tillage, and chemical additives to increase the quality and quantity of crops! This book shows the importance of organic matter in maintaining crop production. The addition of organic matter to soil is covered in great detail. This book is unique in that it draws on practical farming operations to illustrate many of the points discussed. The senior author has had almost 60 years of experience in solving production problems—many of which have been related to insufficient organic matter. In addition, Sustainable Soils: The Place of Organic Matter in Sustaining Soils and Their Productivity stresses the necessity of combining the addition of organic matter with reduced tillage and added chemicals. Photographs, tables, and figures, as well as appendixes containing common and botanical names of plants, symbols and abbreviations found in the text, and useful conversion factors and data help bring the information into focus quickly and efficiently. An extensive bibliography points the way to other useful material on this subject. Sustainable Soils discusses: what materials can be added techniques for proper handling of organic matter how much is enough (and how much is too much!) the nutritive value of various forms of organic matter the benefits that can be expected from properly handling and adding organic matter to soil From the Editors: “Sustainable agriculture is not possible without a sustainable soil science, which in turn is largely dependent on organic matter. It is necessary to return large amounts of organic matter to the soil in order to maintain satisfactory crop production. It can be derived from crop residues, cover crops, sods, or various wastes, such as manures, sludges, and composts. This book details the benefits of various forms, and how each should be handled for maximum returns.”

Structure and Organic Matter Storage in Agricultural Soils by M.R. Carter,B.A. Stewart Pdf

Soils comprise the largest pool of terrestrial carbon and therefore are an important component of carbon storage in the biosphere-atmosphere system. Structure and Organic Matter Storage in Agricultural Soils explores the mechanisms and processes involved in the storage and sequestration of carbon in soils. Focusing on agricultural soils - from tropical to semi-arid types - this new book provides an in-depth look at structure, aggregation, and organic matter retention in world soils. The first two sections of the book introduce readers to the basic issues and scientific concepts, including soil structure, underlying mechanisms and processes, and the importance of agroecosystems as carbon regulators. The third section provides detailed discussions of soil aggregation and organic matter storage under various climates, soil types, and soil management practices. The fourth section addresses current strategies for enhancing organic matter storage in soil, modelling techniques, and measurement methods. Throughout the book, the importance of the soil structure-organic matter storage relationship is emphasized. Anyone involved in soil science, agriculture, agronomy, plant science, or greenhouse gas and global change studies should understand this relationship. Structure and Organic Matter Storage in Agricultural Soils provides an ideal source of information not only on the soil structure-storage relationship itself, but also on key research efforts and direct applications related to the storage of organic matter in agricultural soils.

Soil Organic Matter in Temperate AgroecosystemsLong Term Experiments in North America by Eldor A. Paul,Keith H. Paustian,E. T. Elliott,C. Vernon Cole Pdf

The presence - or absence - of soil organic matter (SOM) has important implications for agricultural productivity. It could also have significant implications for global climate due to its role as a source/sink of carbon. Therefore, it is important to understand the issues related to the accumulation or loss of SOM, to use what we have learned from experiments to make sound decisions about soil and crop management, and to test models and future concepts concerning SOM management. A database is included with the book, presenting tabular data for 34 sites in North America. Soil Organic Matter in Temperate Agroecosystems discusses all of these issues and more, answering such questions as:

Advances in Organic Farming by Vijay Singh Meena,Sunita Kumari Meena,Amitava Rakshit,Johnson Stanley,Srinivasa Rao Pdf

Advances in Organic Farming: Agronomic Soil Management Practices focuses on the integrated interactions between soil-plant-microbe-environment elements in a functioning ecosystem. It explains sustainable nutrient management under organic farming and agriculture, with chapters focusing on the role of nutrient management in sustaining global ecosystems, the remediation of polluted soils, conservation practices, degradation of pollutants, biofertilizers and biopesticides, critical biogeochemical cycles, potential responses for current and impending environmental change, and other critical factors. Organic farming is both challenging and exciting, as its practice of “feeding the soil, not the plant provides opportunity to better understand why some growing methods are preferred over others. In the simplest terms, organic growing is based on maintaining a living soil with a diverse population of micro and macro soil organisms. Organic matter (OM) is maintained in the soil through the addition of compost, animal manure, green manures and the avoidance of excess mechanization. Presents a comprehensive overview of recent advances and new developments in the field OF research within a relevant theoretical framework Highlights the scope of the inexpensive and improved management practices Focuses on the role of nutrient management in sustaining the ecosystems

Modern Agriculture and the Environment by David Rosen,E. Tel-Or,Y. Hadar,Y. Chen Pdf

This volume comprises the proceedings of the First International Rehovot Conference on Modem Agriculture and the Environment, held at the Rehovot Campus of the Faculty of Agriculture, the Hebrew University of Jerusalem, Israel, 2-6 October 1994. The conference, first in a series intended to be convened in Rehovot at 4-5 year intervals to address various aspects of the interaction of agriculture and the environment, was initiated, organised and carried out under the auspices of the Faculty of Agriculture, the leading academic institution in agricultural and environmental studies in Israel. It featured four keynote addresses, 39 invited lectures, 40 submitted papers, and 62 posters. Of these, 51 articles, written by 122 contributing authors from 14 countries, were selected by the editors to be presented in this book. All through the twentieth century, and especially ever since the advent of the Green Revolution, modem agriCUlture has been striving to feed and clothe the ever increasing multitudes of the human species through improved technology, relying heavily on tremendous inputs of fertilisers, pesticides, and various other agrochemicals. Undoubtedly, this has been a great blessing to mankind, and enormous strides have indeed been made in the never-ending struggle against starvation, but these have been achieved at a very steep price of increased environmental deterioration. In fact, modem agriculture has become one of the major factors contributing to the degradation of the world's fragile biosphere.
