Nitrogen (N) released through mineralization from broiler litter can supply the N requirements for crops, but litter may cause yield reductions and loss of fertilizer value if applied in excess of crop needs. A field study was conducted over two year

Runoff, sediment and nutrient losses were studied from 3 tillage systems of cotton ( Gossypium hirsutum L. ‘McNair 235’): (1) no-till without a cover crop (NT); (2) reduced-till with a winter wheat ( Triticum aestivum L. ‘Coker 747’) as a cov

Winter legumes can benefit subsequent crops by improving soil and water conservation, and by providing N. The amount of N produced is influenced by soil pH, fertility level and other factors. Maximum N is essential for returns which will offset produ
