The objective of this field study was to evaluate the performance of a Geotube® dewatering system under field conditions by quantifying the mass removal efficiency of solids, nutrients, and metals from well-mixed dairy-lagoon slurry dewatered by this system.
A Geotube dewatering system was set-up to treat the lagoon slurry mix from the primary lagoon of a 2000-head lactating cow open-lot dairy (Fig. 1). After two synthetic tubes were filled to a height of approximately 1.5 m with …

This fact sheet has been developed to support the implementation of the Natural Resources Conservation Service Feed Management 592 Practice Standard. The Feed Management 592 Practice Standard was adopted by NRCS in 2003 as another tool to assist with addressing resource concerns on livestock and poultry operations. Feed management can assist with reducing the import of nutrients to the farm and reduce the excretion of nutrients in manure.

The air emissions from animal feeding operations have relatively few regulatory oversights. Below is a summary of programs that can apply to animal agriculture. Related page: Air Quality Regulations for Animal Agriculture (curriculum materials).
The following federal laws and their applicability to animal agriculture is discussed in a four page fact sheet “Air Quality Regulation and Animal Agriculture“. (PDF format). These federal laws are enforced by the U.S. Environmental Protection Agency …
The rapidly expanding ethanol industry is producing increasing amounts of corn co-products that will be used in livestock and poultry diets. Inclusion of distillers grains and corn gluten feed in diets alter excretion of nitrogen and phosphorous in manure and therefore impacts nutrient planning. This webcast will explain how feeding ethanol co-products may impact manure nutrient management. The speakers are Joel DeRouchey, Kansas State University who will discuss the impacts for swine and poultry operations. Considerations for beef and dairy …
