METHOD OF TREATMENT OF SOD SOILS WITH SIMULTANEOUS FERTILISER APPLICATION AND SOWING SEEDS AND DEVICE FOR ITS IMPLEMENTATION Russian patent published in 2015 - IPC A01B79/02 A01B49/06 

FIELD: agriculture.

SUBSTANCE: method comprises cutting bands of sod with the width of 1-10 cm with their subsequent undercutting, grinding and dispersion in the form of mulch on the surface of the undisturbed sod. In addition, the milling of sod-free soil bands is carried out with vertical mills, mineral fertilisers are locally applied in soil in the treated soil bands, the soil bed is formed, and sowing of seeds is carried out with covering them with soil ridge. Additionally loosening the soil in a horizontal plane under the undisturbed sod layer is carried out at a depth of 4-8 cm from the surface of the sod and with the width of 8-15 cm on the left and right from the edges of the soil bands treated with vertical mills. The device comprises vertical milling section with casings located on the frame with gear drive, flat circular knives, grinders of sod bands, the fertiliser and seed hoppers with seeding mechanisms, coulters with fertiliser and seed guides, rollers for forming a seed bed, and skids for covering seeds with soil ridges. The device is additionally provided with horizontal milling sections with vertical axes to loosen the soil under the layer of undisturbed sod on the left and right from the edges of the soil band treated with vertical mills.

EFFECT: technology and design enable to reduce water and wind soil erosion, to provide favourable conditions for moisture accumulation, to reduce soil compaction with wheels of vehicles, and to ensure the reduction of energy consumption.
