O sistema de cultivo e a estrutura do solo em cafezal. Parte II

Abstract: Foram verificadas as modificaçoes estruturais ocorridas no solo das ruas de um cafezal, pelo emprego de diferentes métodos de cultivo, em experimento instalado em Latossolo Roxo, no município de Analândia (SP). As porcentagens de distribuição das partículas dentro de classes de tamanho e o diâmetro médio dos agregados do solo foram comparados para os diferentes métodos de cultivo. Após nove anos, de 1973 a 1982, constatou-se diferença significativa quanto ao diâmetro médio dos agregados, pelo emprego da roçade… Show more

“…Yang et al (2007) pointed out that chemical and mechanical methods are the dominant weed control practices in many production systems due to its effectiveness, but noted on the other hand, that weed presence during the rainy season prevented soil erosion. Studies conducted in tropical conditions showed that mechanical and chemical methods for weed control on coffee plantations had a great influence on the soil compaction state (Kurachi & Silveira, 1984;Alcântara & Ferreira, 2000b;Araujo-Junior et al, 2008, soil surface crust formation, erosion and coffee yield (Silveira et al, 1985;Alcântara & Ferreira, 2000a).…”

“…Structural changes resulting from the traditional bare ground weed management system stand out among the main adverse effects of this practice (Kurachi & Silveira, 1984;Silveira & Kurachi, 1985;Faria et al, 1998;Alcântara & Ferreira, 2000a;Araujo-Junior et al, 2008. Structural changes due to improper soil management make coffee plants more susceptible to dry conditions by the reduction of infiltration rate and gas flow into the soil profile.…”
