No-till management results in little or no incorporation of residues and fertilizers with soil. Broadcast fertilization could be inefficient with no-till because phosphorus (P) and potassium (K) accumulate at or near the soil surface. Subsurface banding of fertilizers with planter starter attachments or before planting could be more effective. A long-term study was initiated in 1994 at the Armstrong Farm and at other research farms to evaluate P and K fertilizer placement for corn and soybeans managed with no-till and chisel-plow tillage.
