Available in PDF, EPUB and Kindle. Book excerpt: Soil acidity is a major limitation to crop production in many parts of the world. Plant growth inhibition results from a combination of factors, including aluminum, manganese, and hydrogen ion toxicities and deficiencies of essential elements, particularly calcium, magnesium, phosphorus, and molybdenum. Agricultural management practices and acid precipitation have increased acid inputs into the ecosystem and heightened concern about soil acidity problems. While application of lime has proved to be effective in ameliorating surface soil acidity in many areas, significant soil acidity problems still exist. Scientists from Alberta, Canada, recognized the need to provide a forum for researchers from different disciplines to exchange information and ideas on solving problems of plant growth in acid soils. As a result of their efforts, the First International Symposium on Plant-Soil Interactions at Low pH was held at Grande Prairie, Alberta, Canada, in July 1987. In many acid soil areas, liming materials are not readily available, the cost may be prohibitive, or subsoil acidity cannot be corrected by surface application of lime. New management approaches involving both the plant and the soil are needed in these situations. Progress has been made in the selection and breeding of acid-tolerant plants. However, continued progress will be limited by our lack of understanding of the physiological and biochemical basis of differential acidity tolerance among plants.

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.

Available in PDF, EPUB and Kindle. Book excerpt: Biochar Application: Essential Soil Microbial Ecology outlines the cutting-edge research on the interactions of complex microbial populations and their functional, structural, and compositional dynamics, as well as the microbial ecology of biochar application to soil, the use of different phyto-chemical analyses, possibilities for future research, and recommendations for climate change policy. Biochar, or charcoal produced from plant matter and applied to soil, has become increasingly recognized as having the potential to address multiple contemporary concerns, such as agricultural productivity and contaminated ecosystem amelioration, primarily by removing carbon dioxide from the atmosphere and improving soil functions. Biochar Application is the first reference to offer a complete assessment of the various impacts of biochar on soil and ecosystems, and includes chapters analyzing all aspects of biochar technology and application to soil, from ecogenomic analyses and application ratios to nutrient cycling and next generation sequencing. Written by a team of international authors with interdisciplinary knowledge of biochar, this reference will provide a platform where collaborating teams can find a common resource to establish outcomes and identify future research needs throughout the world. - Includes multiple tables and figures per chapter to aid in analysis and understanding - Includes a comprehensive table of the methods used within the contents, ecosystems, contaminants, future research, and application opportunities explored in the book - Includes knowledge gaps and directions of future research to stimulate further discussion in the field and in climate change policy - Outlines the latest research on the interactions of complex microbial populations and their functional, structural, and compositional dynamics - Offers an assessment of the impacts of biochar on soil and ecosystems

Book excerpt: A zona da mata esta situada no dominio morfologico da Mata Atlantica, na regiao sudeste de Minas Gerais, Brasil, Este dominio acompanha a costa brasileira de norte a sul e esta entre os cinco dos 25 "pontos quentes" da biodiversidade, que ssao as areas de maior biodiversidade vegetal e animal e mais ameaçadas do planeta. Originalmente a Zona da Mata era coberta por florestas, restando atualmente cerca de 7.5% da cobertura original. Os agroecosistemas que se instalaram na regiao apresentam produtividade decrescente devido a intensificaçao do uso do solo, utilizando muitas vezes manejo inadequado. Em 1993, agricultores e pesquisadores, buscando alternativas agricolas mais sustentaveis iniciaram a implementaçao (ou melhoria) de sistemas agroflorestais com café (cultura de maior valor economico) na regiao, acompanhando a vocaçao natural daquele ambiente, originalmente florestado. Os principais objetivos da implantaçao de sistemas agroflorestais foiram: 1) regeneraçao e conservaçao dos solos; 2) diminuiçao do uso de insumos externos na agricultura; 3) aumento ou manuntençao dos niveis de produçao; e 4) melhoria da produtividade. E condiçao necessaria para atingir esses objetivos, a melhor compreensao da ciclagem de nutrientes no solo. O presente trabalho objetivou contribuir para melhorar a compreensao desse aspecto, com enfase no fosforo (p), por se tratasr de um nutriente essencial de baixa disponibilidade na maioria dos ecossitemas e que nos solos tropicais, altamente intemperizados , se constitui no principal limitsante da produçao agricola, A deficiencia em P e causada principalmente pela forte absorçao do H2PO, pelos (hidr)roxidos de aluminio (Al) e ferro (Fe), os quais indisponibilizam grande parte do P total para as plantas cultivadas. A principal estrategia para lidar com o problema da fixaçao de P no tropicos tem sido a adiçao de fertilizantes. Entretanto, e sabido que as reservas minerais de P, necessarias para a produçao de fertilizantes, são limitadas e tem previsao de se esgotar em torno de 100 anos, mantido o atual crescimento do uso de P. Nesse contexto, e necessario o desenvolvimento de estrategias sustentaveis de uso tanto do fertilizante fosfatado aplicado, como do P nativo do solo.Uma dessas estrategias consiste de sistemas agroflorestais.e; c) a raizofera destas arvores podem apresentar caracteristicas distintas, devido a liberaçao de diferentes exsudados, tais como acidos organicos e fosfatases.
