METHOD FOR SOIL PROTECTION PREPARATION FOR SOWING SUNFLOWER Russian patent published in 2024 - IPC A01B79/02 A01B49/02 

FIELD: agriculture.

SUBSTANCE: method includes strip cultivation of the field, a combination of shallow flat-cut loosening and deep nonmoldboard cultivation. After harvesting the forecrop, strips for sowing rows are marked with implement stands when carrying out fine processing. The stands of the working parts of the tillage implement and the coulters of the seeder are subsequently placed on marked strips. In the summer, additional small flat-cut loosening is carried out depending on the appearance of new weed shoots throughout the entire field area. In the autumn, on the strips where the seeds will be sown, the main deep nonmoldboard cultivation is carried out, and in the spring, before sowing, flat-cut loosening is carried out.

EFFECT: method ensures destruction of the capillary structure of the top layer of soil, reduction of wind and water erosion of the soil, mechanical destruction of weeds and reduction of the herbicide load.
