Technical Abstract:
The major nitrogen (N) and phosphorus (P) sources and resources in pasture- based dairy farms are identified and examined. This was done by applying a dairy-based whole-farm simulation model (DAFOSYM) to four scenarios representing different pasture-based dairy systems found in the UK and northeastern US. The four scenarios include major differences in fertilizer and supplemental grain feed inputs and milk production. The N and P results are presented in terms of inputs, outputs, and on-farm storages. The implications are presented and analyzed for managing pasture-based dairy systems now and in the future.
