SUSCETIBILIDADE DE COMPACTAÇÃO DO SOLO EM DIFERENTES TEORES DE UMIDADE E MATÉRIA ORGÂNICA.

Abstract

A compactação do solo provocada por cargas superficiais é, atualmente, um dos principais problemas relativos ao manejo de solos no sistema plantio direto ou plantio convencional. O Preparo do solo deve ser feitos de forma, não quebrar excessivamente os torrões deixando o Maximo possível de resíduos vegetais na superfície, atingir profundidade suficiente para quebrar o adensamento e permitindo uma boa infiltração de águas no solo. Neste experimento foi levado em consideração o teor de umidade, Matéria orgânica e tipo de solo. Foi realizado o experimento em campo com o auxilio do perfilometro determinou o afumdamento, método do anel volumétrico o teor de umidade e densidade do solo. Em Campo foram selecionadas três parcelas de solo e em todas as foram efetuada 1, 5, 10 passada com três repetições no mesmo ponto e em dia e teor de umidade diferente, para verificar o acumulo da compactação ao longo do tempo e em diferentes teores de umidade. O experimento realizado no campo experimental da UNIOESTE nos dias 19/07, 23/08 e 17/10/2007 nestas datas foram determinados o teor de umidade afundamento e densidade.
