Resumo
The different cropping systems and land management change their physical
attributes, reflected in its sustainability. The objective of this study was to evaluate the
resistance of a Plintossolo Háplico (Entisols) penetration mechanics in four depths,
under different land uses (cultivation predecessor, legumes and weeds) in an
Agroforestry System. Penetrometrias were made and collected samples for evaluation of
water content in the soil in an area of 3,000 m2. In use systems in which there legume
showed a lower value of penetration resistance. The cultivation system influenced
values soil resistance to mechanical penetration, as well as the water content of the soil.
