Abstract

No-tillage systems limit 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. Banding of P and K could be more effective than broadcast fertilization by applying nutrients below the soil surface. Therefore, a long-term study was established in 1994 to evaluate P and K fertilizer rates and placement methods for grain yield of corn and soybean managed with no-till and chisel-plow/disk tillage. The study evaluated broadcast, planter-bands, and deep bands until 2001 when the deep-band treatment was discontinued. This report summarizes results since 2002.
