Producers, co-op agronomists, and technical service providers generally are not trained on Revised Universal Soil Loss Equation (RUSLE2) principles and need better understanding of Iowa Phosphorus Index for conservation and nutrient planning.
Six workshops titled RUSLE2 and Iowa Phosphorus Index were delivered in 2005. These workshops, developed in collaboration with USDA Natural Resources Conservation Service (Iowa-NRCS), were held in Iowa Falls, Jefferson, Fort Dodge, Newton, Dows, and Knoxville. A total of 128 participants from Iowa, Illinois, Minnesota, Nebraska, Kansas, and Canada attended these workshops with majority of participants being consultants and service providers. During these workshops, Iowa-NRCS and ISU Extension staff provided hands-on training on Dominant Critical Area Determination, RUSLE2 Operations, Ephemeral & Classical Gully Erosion, Iowa Phosphorus Index calculations, collecting field information, and soil sampling as needed to meet various regulatory requirements.
A total of 120 workshop evaluations were received. Those reporting worked with or managed approximately 1.39 million acres and 2,490 clients on an annual basis. They also reported developing over 1,690 nutrient management plans annually. Benefit gained from the workshop was reported from some to quite a lot. Participants indicated an average gain of $400 per client serviced or $0.71 per acre serviced. The overall average gain was reported as over $7,700 per participant.
Participants completing evaluations provided a pre- and post-workshop level of knowledge in their evaluations. All respondents indicated an average pre-workshop level of knowledge at 39 percent on all topics covered in the workshops. This level of knowledge was raised to over 77 percent based on post-workshop evaluations. Ninety-three percent of the participants reported information provided in workshop as helpful towards meeting their needs in developing conservation and nutrient management plans.
Several comments received during the workshops included: Very well presented thank you, Great Job! Well done. I look forward to working with NRCS, Iowa State University Extension Service, DNR, Very helpful, Very good program as producers need the assistance from service providers, etc.
