Introductory RUSLE2 Soil Loss and Iowa Phosphorus Workshop Planned in December

field A Dec. 13 workshop will provide an opportunity for producers to learn more about the Revised Universal Soil Loss Equation 2 (RUSLE2), as well as the Iowa Phosphorus Index. The workshop will be held in Altoona and is a collaborative effort between the Iowa Department of Natural Resources, the United States Department of Agriculture and Iowa State University Extension and Outreach. Registration is $200, and a Windows compatible computer with a USB port and Microsoft Excel Software is required.

The RUSLE2 equation is a tool stakeholders can use to calculate soil loss for a given field and is necessary for determining the Iowa Phosphorus Index.

The morning portion of the workshop will focus on installing software programs, performing dominant critical area determinations, and operating RUSLE2. The afternoon session will include discussions on ephemeral gully and classical gully erosion and the Iowa Phosphorus Index, which can be used in IDNR manure management plans and open feedlot nutrient management plans.

The workshop will be taught by Kapil Arora, field agricultural engineer with Iowa State University Extension and Outreach; Dan Andersen, associate professor of agricultural and biosystems engineering and extension agriculture engineering specialist at Iowa State University; Don Carrington, United States Department of Agriculture-NRCS and Jeremy Klatt, Iowa Department of Natural Resources.

This workshop qualifies for 6 Certified Crop Advisor (CCA) Credits (5SW, 1NM) and 3 Professional Development Hours (PDH). Participation certificates will be provided upon completion of the workshop.

Registration will be limited to 30 participants and is $200 before Dec. 8, and $225 thereafter. The workshop will be held at the ISU Extension and Outreach Polk County Office, located at 1625 Adventureland Drive, Suite A, Altoona.
