Two dairy waste handling systems : a comparison of nitrogen balances Holbek, Niels Erik
Abstract
Two dairy farms on Vancouver Island, B.C., were studied to evaluate nitrogen behavior under different handling and storage conditions. The first farm (U.B.C.) spreads slurry collected daily on a year round basis, while the second (B.M.) stores its slurry in a concrete pit to land dispose under favourable conditions. Feed analysis, slurry sampling, pit profiles and soil profiles were included in the study. Results showed that the nitrogen content of the manure can be reasonably estimated from either feed nitrogen or milk production. Losses of nitrogen during collection and storage in these systems were minimal.
