This study was conducted during 1998-99 at an experimental field in Kansas, USA to determine the influence of tillage and P placement on P losses in runoff water from a somewhat poorly drained soil (Woodson silt loam (fine, smectitic, thermic Abruptic Argiaquoll), 1.0-1.5% slope) in a grain sorghum (Sorghum bicolor)-soyabean (Glycine max) rotation.
