FIELD: agriculture.;SUBSTANCE: invention refers to agriculture. Method provides soil preparation, following sodding of space between rows with natural or sow grasses and formation of uniform mulching layer. Mulching layer is formed by periodic grass mowing during whole vegetation period. Grass mowing is performed at variable height. Within spring period grass mowing is performed at height 10-15 cm. During summer period mowing height is reduced to 5-10 cm. Grass mowing within autumn and summer period with forecasted incessant or frequent rains is performed at height up to 2-4 cm. If grass height exceeds mowing height by 15 cm and more, mowed mass is milled. During the last mowing for season grass mass is delivered from mowing rotors to support-feed spindle of mower attached along full length of running clamping rolled up to soil agricultural background of space between rows with minimum stubble remains. Such technology allows for higher labile humus fractions content in space between rows soil due to increased vegetative organic chemistry delivered to surface and top layer of soil, for improved microclimate and raised biological activity of soils.;EFFECT: improved microclimate and raised biological activity of soils.;3 cl, 1 tbl, 9 ex
