Abstract
Key performance indicators, such as milk urea nitrogen, ration nitrogen (N) and phosphorus (P) levels, corn stalk nitrate testing, and soil fertility assessments are only useful if we know what to strive for. Similarly, feasibility ranges are needed for whole farm nutrient mass balances (NMBs) as a key performance indicator of nutrient use efficiency at the whole-farm level. In New York, such targets, or feasible balances, were determined for the NMB per acre cropland and the NMB per hundredweight (cwt) of milk produced, based on NMB data from 102 New York dairies. Feasible balances per acre were set at the third quartile of the farm distribution. In other words: if three out of four New York dairy farms operate at or below this NMB, it should be feasible for the fourth farm to also do so. For the balance per cwt farms were divided in two groups, those below and those above, the average balance per cwt for all farms.
