Abstract. On strawberry plantation, the compost, straw, sawdust, wood bark and black plastic foil were used for soil mulching. Mulch with compost had a profitable influence on P and Mg content in soil, and mulch with straw on K content. Effect of sawdust and wood bark on the decrease of K content in soil, and the straw on the decrease of Mg content was noticed in the experiment. Applied mulches modified N, P, K, Mg content in strawberry leaves.

Summary
Field experiment was carried out in years 1994-1997, in climatic and soil conditions of the Vilnus Region. The strawberry plantation was covered by the mulches with compost (peat and organic farm materials), rye straw, sawdust from needle trees, wood bark (from needle trees) and black plastic foil. Content of P, K, Mg in soil and N, P, K, Mg in strawberry ‘Senga Sengana’ leaves, in spring and autumn was determined. A profitable influence of mulch with compost on P and Mg content in soil and mulch with straw on K content was noticed.
Decrease of K content in soil under the mulches with sawdust and wood bark, and Mg content in soil under the mulch with straw was stated. Effect of mulching with sawdust on the decrease of N content in strawberry leaves was observed. The plants from the mulching soil with compost were characterized of the biggest tendency to accumulation of N in strawberry leaves, and mulching with sawdust and compost for Mg accumulation. All sorts of mulches were demonstrated a positive influence on K content in strawberry leaves in comparison with control.
