Deep Ripping Farmland with BIG D10 DOZER

We are deep ripping our farmland with a big D10 dozer. We did soil analysis and there is a hardpan 2 1/2 to 3 feet below the ground. We want to get rid of the hardpan so that the roots can grow deeper into the soil and also to allow better water drainage. Deep ploughing and field leveling using D10 Dozer from Deep Ripping contractor. First the field is ploughed using a deep plough shank, witch is capable of ploughing 6 feet deep. The top layer of clay soil is ploughed under and the lighter sand and peat soil is brought to the surface to make the land more suitable for other crops and easier to work on. After ploughing the field needs to be leveled for improved water coverage and drainage.
