Abstract

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