Two years experiments with bewitch in orchard were done using three grass species: common bird's (Lotus corniculatus), white clover (Trifolium repens) and perennial ryegrass (Lolium perenne). An experiment plot was posed with following variants: a) common bird's, b) perennial ryegrass and c) mixtures of perennial ryegrass (50%) + common bird's (25%) + white clover (25%). The herbage is cut 2 to 3 times per year for mulch the rows of orchards plants. The aim of this experiment is to notice the influence of the mention variants to the increasing of nitrogen, phosphorus and potassium level in the soil through the mulch organic mass. The total yield of herbage is: common bird's - 35.942 kg/ha, perennial ryegrass - 32.843 kg/ha and mixtures of three species - 47.574 kg/ha. We conclude that through the organic mass in the soil is rake in 131-188 kg/ha nitrogen, 49-63 kg/ha phosphorus and 275-308 kg/ha potassium.
