Métodos de preparo do solo: alterações na rugosidade do solo Soil tillage methods: alterations in the roughness of the soil

Abstract

Procurando relacionar os métodos de preparo de solo com alguns dos efeitos em um Latossolo Vermelho distrófico, foi conduzido, no município de Uberaba - MG, um trabalho utilizando-se do delineamento experimental em blocos casualizados, com cinco tratamentos e quatro repetições, tendo como tratamentos os preparos de solo: escarificador, enxada rotativa, arado de aivecas, grade aradora e arado de discos. Foram avaliadas a área mobilizada do solo e a área de elevação, tendo-se como referência a superfície natural do solo antes da mobilização, o empolamento do solo, a espessura média da camada mobilizada, o índice de rugosidade e a modificação da rugosidade do solo para a comparação da rugosidade antes e após sua mobilização. O escarificador proporcionou menor empolamento e maior índice de rugosidade do solo, enquadrando-se como preparo conservacionista por desestruturar menos o solo, podendo colaborar com as menores perdas de solo por erosão.Trying to relate the soil tillage methods with some of their effects in Haplustox, it was installed in the municipal district of Uberaba/MG, a research using a completely randomized experimental design in factorial array with five treatments and four replications. The treatments were composed by the soil tillage: chisel plow, rotary tiller, moldboard plow, disk harrow and disk plow. They were appraised: soil mobilized area, elevation area, medium thickness of the mobilized layer, roughness index and the alteration of the roughness of the soil. It was verified that the chisel plow provided larger roughness index of the soil being framed in the conservationist method disaggregating less the soil, collaborating with the smallest soil losses for erosion.
