Lagoon and Earthen Manure Storage Basin Closure: Part 1 - Estimating the volume, nutrients, and land application needs of accumulated effluent and biosolids

Publish Date: 06/20/2018

The closure of aged livestock lagoons and earthen manure storage basins needs to be conducted in a manner that controls potential environmental risk and makes economical use of accumulated nutrients in the biosolids. In this video, learn how to prepare for the closure of a lagoon by estimating the volume and nutrient content of liquid effluent and accumulated sludge, sampling effluent and sludge, quantifying the value of these products based upon fertilizer nutrient availability and prospective soil fertility impacts, and planning land application activities to utilize these nutrients in crop production systems.

Safe Disposal of Veterinary Pharmaceuticals

Publish Date: 05/15/2013

Pharmaceutical compounds are increasingly being detected at low levels in ground and surface waters. Although environmental concentrations of pharmaceuticals measured to date are far lower than the intended therapeutic doses, there is concern that the potential exists for these chemicals to have an adverse impact on aquatic life and human health. Disposal of pharmaceutical compounds is becoming a complex environmental issue. According to the United States Geological Survey (USGS), little is known about the potential health effects to humans or aquatic organisms exposed to the low levels of most of the chemicals or mixtures commonly found in their studies. But the safety and health of the environment is directly affected by the disposal method, so it is important that we all be responsible when disposing of these products. Presently, the American Veterinary Medical Association (AVMA) does not offer specific guidelines for disposal of pharmaceutical waste, but they do offer an educational video on the subject, available by visiting www.avma.org and searching “drug disposal”.
