The process serves for the loosening of soil in the subsoil and topsoil areas and for introduction of fertilizers as well as subsoil loosening and/or for soil cultivation as well as the introduction of other additives with the use of digging tools 2, 2', and 2'' by which the soil is broken up. In this case, the digging edge of digging tool 2, 2', and 2'' is guided in an elliptical motion and this motion is superimposed by a straight motion, i.e., the driving motion. A cycloid is therefore produced for the digging edge. The longer axis of the ellipse in this case is directed from the soil surface into the soil in this manner and exhibits an angle to the travel direction. The additive, such as, for example, fertilizers, can be blown into the fissure forming behind tool 2.
