Download or read book Efeito de metodos de preparo do solo e de controle de plantas daninhas sobre propriedades fisicas e quimicas de um latossolo roxo eutrofico, cultivado com milho, durante dez anos written by A. F. Ardenghi and published by . This book was released on 1989 with total page 68 pages. Available in PDF, EPUB and Kindle. Book excerpt: Este trabalho foi realizado a partir de amostragem, feita em parcela, no ano agricola 1985/86, de um experimento conduzido, desde 1976, na Central de experimentacao, Pesquisa e Extensao do Triangulo Mineiro (CEPET), da Universidade Federal de Vicosa (UFV), em Capinopolis-MG. Foram estudadas as alteracoes em caracteristicas fisicas e quimicas de um Latossolo Roxo eutrofico (agregados estaveis em agua, densidade aprente, porosidade total, distribuicao de poros, textura, materia organica, pH, potassio e fosforo disponiveis, calcio e magnesio trocaveis), decorrentes do uso de metodos de preparo diferenciados (arado de aiveca, arado de disco plantio direto), associados aos metodos de controle de plantas daninhas: "enxada", herbicida (quimico) e sem controle (testemunha). Os resiltados mostraram que os metodos de preparo do solo atuaram nas caracteristicas fisicas e quimicas deste. No plantio direto, foram encontradas maior densidade aparente e menor porosidade total, no intervalo de profundidade de 0-10 cm, e no arado de aiveca foram obtidos esses mesmos efeitos, para o intervalo de 10-20 cm. Para o arado de disco, associado ao controle quimico, e para o arado de aiveca, associado ao controle "enxada", observou-se maior reducao na percentagem de agregados estaveis em agua, com diametro superior a 2 mm. No plantio direto, foram encontrados maior teor de carbono organico e maior concentracao de fosforo, na camada superficial do solo.

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.

This book was released on 1995 with total page 174 pages. Available in PDF, EPUB and Kindle. Book excerpt: Com a finalidade de buscar a forma mais adequada de manejo do solo em condicoes edafoclimaticas especificas, fez-se o estudo de diferentes sistemas de preparo avaliando-se seus efeitos sobre as caracteristicas fisicas e quimicas que atuam no processo de armazenamento de de agua e na producao de graos da cultura de milho. O trabalho foi realizado aproveitando-se um experimento de manejo do solo iniciado em 1983/84 em um latossolo roxo distrofico muito argiloso(Typic Haplorthox), no Centro Experimental de Campinas, do Instituto Agronomico. Os tratamentos utilizados foram os de milho rotacionado com soja, apos aveia preta cultivada no outono-inverno, sob preparo com escarificador, arado de discos (convencional) e plantio direto, com tres repeticoes. As avaliacoesdeste estudo ocorreram em 1990/91, quando se determinou: potencial no ciclo do milho, densidade do solo, resistencia a penetracao, com penetrometro de bolso, densidade de raizes, fertilidade do solo, cobertura morta e pela cultura, retencao de agua ate 1.500 KPa, capacidade de aeracao e de agua disponivel, infiltracao e condutividade hidraulica com permeametro e pelo metodo de saturacao do perfil, e producao de graosda cultura de milho. Os resultados obtidos revelaram que o plantio direto apresentou mais beneficios ao desenvolvimento das plantas e ao solo que o sistema convencional, entre os quais pode-se destacar: acumulo de materia organica e fosforo proximo a superficie, maior homogeneidade ao longo do perfil quanto a estrutura, com melhor ...

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.
