This book was released on 1981 with total page 92 pages. Available in PDF, EPUB and Kindle. Book excerpt: Tres sistemas de manejo do solo - o convencional, o preparo reduzido e o plantio direto - foram estudados com relacao aos seus efeitos sobre a producao do milho, sobre as perdas por erosao, sobre a umidade do solo, sobre o estado de agregacao das particulas, sobre o rendimento de trabalho e consumo de combustivel. Os estudos foram desenvolvidos em quatro unidades de solo do Estado de Sao Paulo: Latossolo Roxo, Solo Podzolico Vermelho-Amarelo orto, solo Pozolico Vermelho-Amarelo variacao Piracicaba e solo Podzolico Lins e Marilia variacao Marilia. Os resultados obtidos para cada unidade de solo foram as seguintes: 1. Latossolo Roxo - a. A producao de milho em graos, em kg/ha, nao diferiu estatisticamente nos tres sistemas de manejo. b. O plantio direto foi superior ao sistema de manejo convencional nos seguintes itens: - reduziu em 59,0% as perdas de terra em t/ha na declividade de 6,3 %, e reduziu em 34,0 % as perdas de agua em mm; - aumentou o indice dos agregados de diametros medio estaveis em agua. c. Apresentou igual ou maior disponibilidade de agua para as plantas durante o ciclo vegetativo do milho. 2. Solo Podzolico Vermelho-Amarelo orto - a. A producao de milho em graos, e, kg/ha, foi estatisticamente superior no sistema de manejo convencional e no preparo reduzido, quando comparada com o plantio direto; b. O plantio direto foi superior ao preparo reduzido e ao sistema de manejo convencional quanto a eficiencia de trabalho (25,0 %, 70,5 % e 100 % de tempo relativo necessario, respectivamente) e, no (...).

Download or read book Conservation Agriculture written by L. García-Torres and published by Springer Science & Business Media. This book was released on 2013-04-17 with total page 506 pages. Available in PDF, EPUB and Kindle. Book excerpt: In large parts of the developed and developing worlds soil tillage by plough or hoe is the main cause of land degradation leading to stagnating or even declining production levels and increasing production cost. It causes the soil to become more dense and compacted, the organic matter content to be reduced and water runoff and soil erosion to increase. It also leads to droughts becoming more severe and the soil becoming less fertile and less responsive to fertiliser. This book brings together the key notes lectures and other outstanding contributions of the I World Congress on Conservation Agriculture and provides an updated view of the environment and economic advantages of CA and of its implementation in diferent areas of the World.

Download or read book Managing Organic Matter in Tropical Soils: Scope and Limitations written by Christopher Martius and published by Springer Science & Business Media. This book was released on 2002-01-31 with total page 260 pages. Available in PDF, EPUB and Kindle. Book excerpt: Soil organic matter is a reservoir for plant nutrients, provides water-holding capacity, stabilizes soil structure against compaction and erosion, and thus determines soil productivity. All agriculture to some degree depends on soil organic matter. It has long been known that soil organic matter declines when land is taken into cultivation, and that the productivity of new agricultural land is governed by fertility contributions from decomposing natural organic matter. The expansion of agriculture to ever new and more fragile lands, particularly in tropical and developing regions, causes environmental degradation with local effects on soil quality, regional effects on landscape integrity and water quality, and global effects on carbon cycles and the atmosphere. This book summarizes current knowledge of the properties and dynamics of soil organic matter in the tropics, its role in determining soil quality, its stability and turnover, and the options for management in the context of tropical landuse systems, for a readership of resource scientists, economists and advanced students. Maintenance of organic matter is critical for preventing land degradation. Case studies and practical applications are therefore an important part of the book, as are the exploration of future directions in research and management.

Download or read book Caracteristicas quimicas do solo, nutricao e rendimento do milho afetados por metodos de preparo e sistemas de culturas written by C. Bayer and published by . This book was released on 1992 with total page 172 pages. Available in PDF, EPUB and Kindle. Book excerpt: Um experimento estabelecido ha 5 anos em um solo Podzolico Vermelho-escuro (PALEUDULT) com sinais visiveis de degradacao pelo mau uso, localizado na EEA/UFRGS-Eldorado do Sul/RS, foi amostrado com o objetivo de avaliar o efeito de metodos de preparo de solo (convencional, reduzido e sem preparo) e sistemas de culturas (aveia (Avena strigosa) /milho, aveia+trevo (Trifolium subterraneum) /milho e aveia+trevo/milho+caupi (Vigna unguiculata)) sobre as caracteristicas quimicas do solo, absorcao de nutrientes e rendimento do milho. A associacao dos metodos de preparo que promovem menor revolvimento do solo e dos sistemas de culturas que produzem maiores quantidades de residuos resultou em maiores valores de carbono organico total, capacidade de troca de cations, nitrogenio e outros nutrientes na camada superficial do solo. Os metodos de preparo de solo nao afetaram o rendimento do milho, enquanto que, os sistemas de culturas tiveram efeito sobre o rendimento, principalmente pela maior disponibilidade de nitrogenio nos sistemas com leguminosas. A disponibilidade de nitrogenio afetou tambem a absorcao dos demais nutrientes.
