摘要

Most tillage and fertilizer practices attempt to maximize cash crop yields and do not focus on increasing cover crop yields. This project was conducted to determine the optimum time to perform in-row subsoiling in order to maximize cash crop and cover crop production. Two implements (Paratill or a KMC Rip/Strip) were used to perform in-row subsoiling at 6-week intervals beginning in the late fall in actively growing cover crops. Results indicated that maximum yields occurred for the cash crop and the cover crop by performing in-row subsoiling late in the spring after the cover crop had been terminated. All in-row subsoiling treatments were found to be superior to no-tillage which exhibited reduced plant growth, infiltration, and increased soil compaction.
