It is intended for strip processing of soil, under cultivated crops with the simultaneous application of mineral fertilizers. With the help of three painters (turbines), high-quality soil loosening is carried out. Fertilizers can be introduced in two independent ways:
1) fertilization of fertilizers on one of the working wheels of the aggregate, which ensures the mixing of fertilizers in the treated strip;
2) applying fertilizers to the bottom of the cultivating strip or deeper with the ramming belt.
Unit utilization efficiency:
• Only 30% of the field surface is processed (saving the POL);
• Mineral fertilizers are introduced (consumed at later stages of plant development);
• Multi-row spacing (do not give the moisture to intensively evaporate);
• In the spring, the black stripes get warmer faster (early sowing).
