Yielding effect of catch crops biomass was higher on loamy sand than on brown alluvial soil. Straw incorporation as even straw surface mulching during winter decreased 10% yield of barley. Surface plant biomass mulching and soil cultivation before barley sowing decreased its yield neither. Catch crop cultivation reduced soil moisture underneath in autumn, but mulching during winter increased soil water storage in sowing time spring barley. Soil nitrogen content after ending catch crop vegetation had been lower about 30% , comparing with soil without catch crop. Nitrogen release from plant residues incorporated with soil before winter was higher than from residues left on the surface
