Stubble cultivation is vital in conservation tillage: it incorporates weed and volunteer cereal seeds into the soil with intensive mixing and promotes germination for more efficient subsequent treatment. The even incorporation of straw is a key factor for seed germination. The Kubota CD2001T Series of disc cultivators is ready for shallow and deep cultivation and straw mixing. The CD2001T shows excellent performance with large amounts of residue (straw, intermediate green crops etc.) thanks to its small notched conical discs.
