Subsoilers are intended only for deep soil cultivation without compromising its top layer. They loosen and aerate the soil.Subsoiling breaks the "plow-shaped sole" thereby restoring normal water and air conditions in the soil. In this tillage type doesn't mix the surface and deep layers of the soil. It should preferably be done immediately after harvest, when the soil is dry. The machine can also be used to prepare the soil before planting fruit trees, berry bushes and plants with deep root system.
