Abstract
The check plots were placed on the hill with 10% slope in Agriculture Research and Development Station Oradea in 1999. The metal panels at the base and soil dams there were between the plots. The variants studied: clean fallow, pasture, wheat, maize on the level curves, and maize from hill to valley. The biggest soil losses were determined in the variant with clean fallow and in variants with maize seeded from hill to valley. The erosion determined the important differences between the physical parameters (hydrostability of the macrostructure – aggregates bigger than 0.25 mm, bulk density, total porosity, hydraulic conductivity, penetration resistance) of the soil in the top of the hill in comparison with the base of the hill. In the top of the hill, the values of the physical parameters were less favorable for plants in comparison with the hill base. The most unfavorable values of the physical properties of the soil were registered in the variant with clean fallow fallowing the variants cropped with maize from hill to valley, the variants cropped with maize on the level curves, wheat and pasture.
