Sleif harrow tooth BSHN-14, BSHN-17, BSHN-21 Solomiya, Dnepropetrovsk region.

Sleif-tooth harrow BSHN-14, BSHN-17, BSHN-21
The work of the harrow is intended for works such as early spring:
- preservation of moisture, crushing of clods, leveling of the field surface, distribution of remains that have not rotted after winter;
- acceleration of drying of the top layer of soil (5 cm), for the possibility of carrying out earlier sowing without weathering of moisture;
- laying of mineral fertilizers and soil herbicides;
- provoking the germination of weed seeds, and destroying their seedlings during further processing.
Summer period, grain harvesting:
- provoking the germination of weed seeds by shallow processing of stubble after harvesting (instead of peeling, when the soil is not overdried)
- uniform distribution of harvest residues on the surface of the field, mulching to accumulate a large amount of moisture and retain it in the soil. Prevention of water and wind soil erosion .
Autumn period:
- provoking the germination of weed seeds, and destroying their seedlings during further processing;
- crushing of clods, leveling of the field surface, distribution of plant residues for high-quality sowing of winter crops;
- laying of mineral fertilizers and soil herbicides.
