Phosphorus Runoff from Sugarbeet Production Systems as Affected by Tillage and Phosphorus Fertilizer Placement

Abstract

Sugarbeet production systems are potentially vulnerable to significant phosphorus (P) losses. Production practices that may reduce P loss risk are being considered. However, the potential benefits of these practices are not well estab­ lished. A rainfall simulation study was conducted to deter­ mine P losses from various tillage (moldboard, chisel, and deep chisel) and phosphorus fertilizer placement (broad­ cast and band). Sugarbeet (Beta vulgaris L.) corn (Zea mays L.), and soybean (Glycine max L.) rotations were studied. A rainfall simulator was used to create runoff ** '-<
