Interpretive Summary

The objectives of this research are to determine how interactions between cover crops and phosphorus (P) fertilizer management impact P loss, P use efficiency, crop yield, and net return. A watershed study at the Kansas Agricultural Watershed Field Laboratory (near Manhattan) has been established to address these objectives. The study consists of 18 small (1. 2 to 1. 5 A) watersheds equipped with automated runoff monitoring equipment.
