Snap-Shot Assessments of Nutrient Use on Dairy Farms

Nutrient Use Efficiency

Escalations in feed and fertilizer cost, and ebbing milk prices are motivating many dairy farmers to find new ways to improve nutrient use efficiency (NUE) on their farms. But how can NUE be determined and monitored easily on dairy farms, and what improvement in NUE can be realistically expected? Over the past several years researchers at the U.S. Dairy Forage Research Center and the University of Wisconsin-Madison have been developing and using rapid assessment methods to provide …

Copper Sulfate Foot Baths on Dairies and Crop Toxicities

Environmental Issues for Land Applying Copper Sulfate

A rising concern with the application of dairy wastes to agricultural fields is the accumulation of copper (Cu) in the soil. Copper sulfate (CuSO4) from cattle footbaths is washed out of dairy barns and into wastewater lagoons. The addition of CuSO4 baths can increase Cu concentration significantly in manure slurry, from approximately 5.0 grams per 1,000 liters to 90.0 grams per 1,000 liters. The Cu-enriched dairy waste is then applied …
