Interpretive Summary: This study was conducted to evaluate effects of P and N-based manure and compost applications on corn yield and soil P level. Annual or biennial manure or compost application resulted in corn grain yields similar to those with chemical fertilizer application. P-based manure or compost application resulted in similar corn grain yield but significantly less soil P build-up than N-based treatments. Estimated N availability was 40% for manure and 15% for compost in the first year and was 18% for manure and 8% for compost in the second year after application. Surface soil levels of total carbon, total N, nitrate, pH, and electrical conductivity were increased significantly following four year of manure or compost application. The changes in soil properties were greater for N than P-based applications.
