Abstract

Trials have been established in 2007 at the Experimental Centre for fodder crops Preajba (Gorj department) according to the Perieni model, for 3 crops (corn, natural and seeded pasture). The trials had 3 variants and 3 repetitions in order to determine the soil loss through water erosion along with the humus and nutrients loss.
The highest soil losses through water erosion were registered at the corn standard trial – 5, 8 t/ha/year, and the lowest at the natural meadow fertilized with N100P90K60 trial – 0, 38 t/ha/year. Low result for the soil loss was obtained for the seeded meadow, fertilized as well with N100P90K60 – 0, 45 t/ha/year. The humus, N, P, and K losses are varying accordingly.
The soil losses are almost insesizable through analytical analysis in 2007, but we have to mention the fact that the effects are cumulative in time, the soil loss determining important effects on the soil structure and fertility.
