Evidence has shown that strip-till systems combine many of the best aspects of no-till and conventional tillage systems. The advantages of strip-till are generally most pronounced for corn following corn, where strip-till can help improve seedbed uniformity and reduce plant-to-plant variability compared to no-till.
Benefits over no-till systems
Strip tillage practices encourage more favorable soil temperature, moisture and aeration conditions for germinating seeds and seedling plants. This can translate to improved crop establishment and early season performance. Strip-till also offers the opportunity to place fertilizers directly into the root zone, away from crop residues that could otherwise intercept or immobilize nutrients.
Benefits over conventional tillage systems
Strip-till can provide conservation and efficiency benefits over conventional tillage practices. By leaving the inter-row untilled, crop residues are retained on the soil surface providing increased erosion resistance and organic inputs. Strip-till can also reduce field passes and input costs compared to conventional tillage.
Tips for successful strip-till
Consider field selection, tillage timing and strip placement when incorporating strip-till into your operation. Guidance systems and strip-till units with parallel linkage help ensure accurate seed placement and consistent depth control. It may take a season or two to become skilled at staying on the strips—so give it time and stick with it.
