The purpose of this project was to quantify the odor and gas emission benefits of a fine ground rubber cover on laboratory scale manure storage units and to evaluate the ability of a fine ground rubber cover applied to a commercial swine manure storage unit to remain intact and functional over an extended period of time. A three-inch cover of fine ground rubber reduced odors by 77 to 99 percent from the manure storage tanks over a six-week period. However, consistent reductions of NH3 emissions were not observed and H2S emissions from all manure storage treatments were …

The objective of this program was to provide producers and ag advisors the skills needed to apply for and maintain the non-engineering components of a Nebraska permit to operate a livestock waste control facility. This includes a Comprehensive Nutrient Management Plan (CNMP). Eighty six producers and advisors participated in an intensive three-session hands-on class with a total of nine contact hours at four sites in eastern Nebraska in the spring of 2002. The workshop included lecture and participant use of spreadsheet tools to assist with performing the necessary calculations. With an average of 68 % responses per session, 58% rated …

This paper introduces the LPES curriculum project, summarizing the curriculum development process, the final curriculum materials, and the outreach activities. Following an overview of the LPES Curriculum Impact Survey, the authors will present representative examples of uses and modifications made of the LPES curriculum as it is used with targeted audiences. This model for utilizing national expertise to address state and local educational needs may have benefit in other extension education programs as land grant university resources decrease. The paper concludes with a discussion of lessons learned from this national extension education curriculum development effort.
