Abstract

No-till management limits the incorporation of crop residue and fertilizer with soil, which results in wetter and colder soils in early spring and accumulation of organic matter, phosphorus (P) and potassium (K) near the soil surface. Subsurface banding of P and K could be more effective than broadcast fertilization by applying nutrients below the soil surface.
