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