Soil Tillage with a Tractor and Disc Harrow
Following the grain harvest, fields remain covered with dry stubble and root stalks. A powerful farm tractor hauls a disc harrow over the ground to break up the hard surface. Concave steel blades roll through the earth, cutting leftover stalks into small pieces while turning the top layer of soil to prepare it for future planting.
How Disc Harrows Improve Soil Health
Discing post-harvest fields plays a crucial role in sustainable soil management. Mixing remaining organic plant matter into the upper soil layer accelerates decomposition, returning valuable nutrients back into the earth. The rotating steel discs also break up hard clods of dirt, preventing surface erosion while improving water absorption during autumn rains.
