Abstract

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.
