The present study considers some results on the quality of plant production in relation with different fertilizer rates. Three-year's fertilization field experimnts were carried out on the severally eroded pastoral lands with 20 cm thickness near to village of Valkosel in Sofia district. The experiment was located on two places to a distance 500 m with different erosion degradation and nutrient supplies. Of the six variants of fertilization the most efficient about plant protein accumulation provided the N6K6 rate for both experimental places.
