Resumen:
The handle system can affect physics quality of agricultural soil, how bulk density,
porosity, over there of reserves the organic matter distributes in the layers agriculturally. This work
has the objective of evaluating the effect of the no-till in an area after eight consecutive years and of
the minimum till in other an area after eight years of no-till, and both areas received soy culture in the
summer and corn in the winter. They were evaluated the parameters of bulk density, organic matter,
total porosity, macro and micro porosity in the soil compaction and soybean yield. The research was
carried out in a Latossolo Vermelho distroférico, in soil samples in layers of 0 to 0.05, 0.05 to 0.1,
0.10 to 0.15 and 0.15 to 0.20 m. The results showed that the bulk density decreased with the increase
of the organic matter. The bulk density was larger in the no-till system, and in the layer of 0 to 0,05 m,
it was smaller for both treatments. The organic matter values presented significant differences among
the two systems being 4% larger for the minimum till.
