METHOD OF ACCUMULATING MOISTURE IN SOIL IN CULTIVATING AGRICULTURAL CROPS Russian patent published in 2014 - IPC A01B79/02 A01G1/00 

FIELD: agriculture.

SUBSTANCE: method comprises loosening of arable and subsurface soil layers 0.10-0.18 m below theplough sole, formation of water-absorbent gaps with their filling with plant and root residues and applied organic fertilizers. At that the para-ploughing is carried out with the intervals of 0.5-0.7 m. And in the arable layer, in the middle part of the gap, the drainage channels are made, and the chopped and evenly distributed straw after harvesting is combed out of stubble, moved into the gap space and embedded in the made gaps, in soil ecotones in the form of bands of fluffy consistency, saturated with organic matter and soil microflora. Along the made gaps the tilled crops are planted. The main crop cultivation is carried out in the spaces between the gaps, and the tillage units are moved along the fixed routes with a deviation of no more than 5-10 cm. The soil loosening and replenishment of organic matter of soil ecotones with straw residues is carried out after harvesting of spiked cereals as necessary, and during the rest time for embedding of the plant and stubble residues the methods of surface tillage are used.

EFFECT: method enables to increase agricultural crop yield in years different in the amount of rainfall through rational redistribution of moisture, organic residues in the soil and precise placement of tilled crops on bioreclaimed plots of agrolandscape located in the form of bands - soil ecotones promoting more efficient use of natural resources of moisture and soil fertility.
