Abstract
Descrição
A mecanização do sistema de colheita do café reduz o custo de produção, porém existe a hipótese da degradação física do solo devido ao aumento considerável do tráfego de máquinas. Objetivou-se, no presente trabalho, avaliar a resistência do solo à penetração em dois sistemas de cultivo da lavoura cafeeira e foi desenvolvido no município de Três Corações –MG, numa lavoura dividida em duas glebas: uma onde realizaram-se todos os tratos culturais mecanizados e em outra gleba realizaram-se manualmente. As mensurações foram realizadas com o auxílio de um penetrômetro digital na linha de cultivo, na linha de tráfego e no centro das entrelinhas da cultura. Conclui-se que o sistema de cultivo mecanizado apresenta maiores valores de resistência do solo à penetração até a profundidade de 0,15 m e menor umidade, quando comparado ao sistema de cultivo manual.
Coffee harvesting mechanization systems reduce production costs, however, there is the chance of soil physical degradation due to considerable increase of machinery traffic. The objective of the present study was to evaluate the soil resistance to penetration in two coffee plantation systems and was developed in the municipality of Tres Corações – MG, in a farming divided in two turfs: one where all of the cultivation treatments were performed mechanically and one other turf where the treatments were performed manually. Measurements were performed with the help of a digital penetrometer in the cultivation line, traffic line and in the center of the cultivation leadings. The conclusion was that the mechanized cultivation system presents greater soil resistance values to penetration down to 0,15m depths and les humidity, when compared to the manual cultivation system.
