METHOD FOR INCREASING THE UNIFORMITY OF SNOW MELTING AND ACHIEVE PHYSICAL RIPENESS OF THE SOIL IN THE FIELD Russian patent published in 2021 - IPC C09K17/06 E02B11/00 A01B13/16 

FIELD: agriculture.

SUBSTANCE: invention relates to the field of agriculture. The method includes carrying out digital survey of the field surface in autumn with fixing the location and parameters of the saucer-shaped depressions of the field microrelief. In the spring, during the period of snow melting, a mixture consisting of 90-95% calcium chloride and 10-5% ash is sprayed on the snow surface over the marked saucer-shaped depressions of the field microrelief.

EFFECT: method provides acceleration of the processes of snow melting and absorption of melt water into the depth of the soil layer, which ensures the release of the field from flood waters and the achievement of physical maturity of the soil simultaneously on its entire surface.
