No-till management results in little or no incorporation of crop residues and fertilizers with soil. Subsurface banding phosphorus (P) or potassium (K) fertilizers could be more effective than broadcast fertilization because both nutrients accumulate at or near the soil surface. Therefore, a long-term study was initiated in 1994 at this farm to evaluate P and K fertilizer application rates and placement methods for corn and soybean managed with no-till and chisel-plow tillage.
