METHOD FOR ADDING ASH MINERAL ADDITIVES TO THE SOIL Russian patent published in 2021 - IPC A01C21/00 C09K17/06 A01B13/16 

FIELD: agriculture.

SUBSTANCE: invention relates to the field of agriculture, in particular to field cultivation. In the method, fly ash of coal burned at a thermal power plant is used as ash mineral additives. The fly ash of brown coal with a fineness of up to 100 microns is used, which is applied with a layer of 1-10 mm on the first snow cover with a frozen upper layer of soil 1-2 cm in depth. Lignite fly ash is applied to a snow cover 3-8 cm thick, high-calcium brown coal fly ash obtained by burning coal at temperatures up to 1600°C is used. When bringing ash-carryover of brown coal into the soil, the route of the tractor with the spreader is chosen taking into account the trail aerosol darkening of the snow during the previous pass of the field.

EFFECT: invention provides an increase in the efficiency of adding ash additives to the soil, preventing their drift and leaching, enriching the soil with microelements and increasing the pH of the soil by 1-2 units.
