Soil and yield losses under the influence of the crop system on applied on the erosioned soils from North-Western Romania.

The researches were carried during 2009-2011 in the Agricultural Research and Development Station Oradea in the plots for check flow. The soil losses were determined every year; the biggest were registered in the variant with clean fallow, followed by the variants with maize seeded from top to valley, maize seeded on the level curves, wheat and pasture. The soil erosion had a bigger effect in the variant with maize seeded from top to valley in comparison with the variant with maize seeded on the level curves because bigger differences were registered between the yields from top of the hill in comparison with the yields registered at the base of the hill.
