If you are an owner or employee on a permitted animal feeding operation, you know very well that maintaining complete and accurate manure management records is necessary to comply with your nutrient management plan (NMP). While you may have enough land within your operation to utilize all manure nutrients produced, it is quite common for manure to be transported from a livestock operation where it was produced to a neighboring crop farm for land application.

Land Application Training events are coming up in February. Several new hands-on activities will focus on using weather forecasts to minimize manure application odors, considering where to stockpile manure prior to land application, selecting the “best” routes for hauling manure to fields and defining who is responsible for manure under various scenarios.

A resource reality of cattle production is that only 10-30% of the nitrogen (N) that is consumed (i.e. fed protein) is utilized by animals for growth, reproduction, milk production, and maintenance needs. Unused N is excreted, primarily in urine. While livestock production is not the only source of N, producers should recognize that agriculture is clearly the dominant contributor of N to the environment on regional and national scales, and animal manure is a key source along with commercial fertilizer. In April of 2017, the DC Circuit Court of Appeals ruled that EPA would have to require animal feeding operations to report ammonia emissions. EPA expects to receive a court mandate on January 22, 2018, enforcing its ruling and opening livestock and poultry operations to consideration under CERCLA/EPCRA.
