erosive processes. The objective of the present study was to compare the effect of different systems of soil
cover on the losses of soil and water. For this, an experiment was carried out on soil models containing soil
classified as Cambisol, at a slope of 7%. The treatments were maize cultivation more canola straw; canola
straw; and uncovered soil. In the treatments that received canola straw, there was used 40 g of straw.pot-1,
equivalent to approximately 7 t.ha-1. For the measurement of the soil and water loss, the infiltrated water
and the surface water were collected, and the lost water and soil were quantified. It was possible to verify
differences between the treatments in terms of soil losses due to surface erosion, being the treatment without
soil cover with the highest soil loss, equivalent to approximately 60 kg soil.ha-1, while in the treatment of
canola straw with maize crop there were no soil losses. There was a superficial loss of water in all
treatments, and there was no difference between them.

Após os tráfegos para indução da tráfego de trator sobre solo após a chuva e tráfego de bovino sobre solo após a chuva. Foi observada redução da VIB onde houve compactação do solo por tráfego de trator sobre solo após a chuva. A compactação observada, por trânsito de trator ou pisoteio de bovinos após a chuva, induziu aumento na densidade do solo o que está diretamente relacionado à redução da porosidade total do solo. Estas alterações na proporção das fases sólida e gasosa do solo, frequentemente estão associadas a restrições ao crescimento radicular das plantas, restrições à PALAVRAS-CHAVE: manejo do solo, densidade do solo, porosidade do solo, degradação do solo
