“Nutrient Management and the U.S. Dairy Industry in 2002,” a report compiled by the National Animal Health Monitoring System, takes an in-depth look at nutrient-management practices on U.S. dairies.
It found that more than half of large dairy operations surveyed analyzed manure for nutrient content, compared to approximately four out of 10 medium operations and less than two out of 10 small operations. It also notes that about half — 55.8 and 48.4 percent, respectively — of large- and medium-sized operations had written nutrient-management plans, compared to only 23.3 percent of small operations.
