See what farms are using for nutrient management, from anaerobic digesters and storage to field application and emissions.


Since 2000, anaerobic digesters on livestock farms have reduced greenhouse gas emission by 19 millionmetric tons of CO2 equivalent. That reduction is equivalent to other potential reductions or mitigations listed in the PDF below.

Dairy farmers may not have to dig too deep, learn to maintain new equipment or radically change production practices in order to reduce nitrogen runoff from agricultural fields. Good manure management, along with help from a few friendly microbes, may be the next big thing in cleaning up our waterways.
