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

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 ** '-<
