A new machine for surface tillage to control the aggregate composition of the soil was tested. The field trial data were processed by applying a statistical data processing software and regression equations were derived describing the fragmentation of soil aggregates of different sizes - 1 mm, from 1 to 25 mm, over 25 mm at different speeds. The regression equations are in GIS with velocity speed and current humidity and increased and decreased by 20% soil moisture. There are layers of fragmentation of soil aggregates visualizing regression equation for units from 1 to 25 mm to optimize the aggregate composition.
