<abstract xmlns="http://www.w3.org/1999/xhtml"><p> Conducted research involved evaluation of selected soil properties in eggplant cultivation with the use of living mulches from white clover and perennial ryegrass. The mulching species were sown three weeks before eggplant planting, in the term of planting and three weeks after planting this vegetable. In half of August there was assessed stability of soil aggregates on the basis of the following indicators of: cloddiness (B), misting (S), structure (W) of the soil and mean weighed diameter of aggregates - the dry method (MWDa), as well as water stability ( MWD) and waterproof (Wod) index of soil aggregates and mean weighed diameter of aggregates - the wet method (MWDg).
