Abstract
A study was initiated in 1994 to evaluate long-term effects of phosphorus (P) and potassium (K) fertilizer rates and placement methods on yield of corn and soybean managed with no-till or chisel-plow tillage. No-till management results in little or no incorporation of residue and fertilizer with soil. Broadcast fertilization could be inefficient with no-till because both nutrients accumulate near the soil surface. Therefore, subsurface banding of P and K fertilizers could be more effective.
