Demixing effect of the rotary cultivator
The “on-grip” tine position has proved its effectiveness particularly when mulch sowing as it guarantees a thorough mixing of soil and organic residues. Tines “on grip” break up the soil from underneath. No smeared layers. Coarse soil particles are thrown further than the light ones. In this way the fine soil is concentrated in the lower range of the worked zone whereas the coarser soil particles remain on the surface. The seed is therefore placed in the area where the fine soil is collected with the coarser clods staying on the surface to protect the soil from capping, drying and wind and water erosion, and provide protection for young plants. This creates the optimum conditions for good seedling emergence.
