METHOD OF ENRICHING SOILS UNDER POTATO CULTIVATION IN GRAIN-TILLED CROP ROTATION Russian patent published in 2016 - IPC A01B79/02 A01C21/00 

FIELD: agriculture.

SUBSTANCE: invention relates to agriculture. Method includes application of organic fertilizers and placement of fertilizers with the help of disk harrows to a depth of 10…12 cm. Further, the green manure crop is seeded, which, with accumulation of a green mass is placed into soil using disk harrows. Then ploughing and cultivation are carried out. Animal manure is introduced as an organic fertilizer. Prior to ploughing, the animal manure is uniformly distributed over the soil surface in a dose of 8…10 t/ha. After ploughing, green manure crop is seeded. In autumn, accumulated green mass of manure and weeds is embedded into the soil by disk harrows to a depth of 10…12 cm. Then the mass is ploughed for winter tillage to a depth of 15…20 cm. Animal manure is introduced repeatedly in spring. Winter tillage is replowed and cultivated and then potatoes are planted.

EFFECT: such technology allows to increase the nutrient-supplying capacity of topsoil and potato yield.
