METHOD OF SOIL TREATMENT Russian patent published in 2012 - IPC A01B79/02 G01N33/24 

FIELD: agriculture.

SUBSTANCE: invention relates to the field of agriculture. The method includes an autumn surface and spring combined treatment by giving the inhomogeneous structure to the arable layer. To reduce the impact of adverse weather conditions on the yield of crops, the inhomogeneous structure is formed simultaneously with the sowing in the layer below the level of seeding by creation of alternate sites having the density favourable for the plants, respectively, in case of the lack and excess of rainfall and the difference between the density of adjacent sites at 0.2-0.3 g/cm³. The value of density for sites designed for the lack of rainfall is 1.3-1.4 g/cm³, for the sites designed for excess of rainfall is 1.0-1.1 g/cm³. In case of an equality of natural soil density corresponding to the density of one of two types of the formed sites it is allowed to use a combination of "treated area - untreated area". Sizes of sites are selected according to the agro-physical soil properties and the average annual weather conditions in the region.

EFFECT: method enables to increase the yield of grain by 6-19% due to the greater adaptability of the field to the weather conditions.
