Abstract. The influence of conservation tillage (no-tillage with mulching) on contents of mineral components in soil and parsley roots was investigated. No-tillage cultivation system did not have a significant influence on mineral contents in soil. The effect of mulching was dependent on kind of cover crops.

Summary
Field experiment was carried out in the years 1999-2000 on the lessive soil with parsley cv.’Berlińska’ cultivation. The effect of conservation tillage (no-tillage cultivation system and cover crop mulches: Sinapis alba, Vicia sativa, Phacelia tanacetifolia, Avena sativa) on contents of some mineral components in soil and parsley roots was investigated. No-tillage cultivation system did not have a significant influence on mineral contents in soil. White mustard and spring vetch mulches had a positive influence on contents of N and K in soil. Direct sowing decreased contents of K, Mg, N-total, N-NO3 in parsley roots comparison to conventional tillage. Under mulching with spring vetch N-total, N-NO3 and Mg contents in parsley roots were the highest of all objects. The significant higher content of K in roots was found after white mustard mulch.
