Title:
RUSLE2 and Iowa Phosphorus Index Workshops Follow-up Evaluation
(Revised Universal Soil Loss Equation, Version 2)

Issue:
Need exists to increase the adoption and implementation of conservation practices as related to utilization of indices and diagnostic tools for improved nutrient management.

Response: 
Twenty workshops on RUSLE2 and Iowa Phosphorus Index have been conducted since 2005 targeted towards service providers with the goal to educate about the use of nutrient management indices.  Over 500 participants representing over 5,500 clients and servicing 2.51 million acres have been trained on utilization of nutrient management indices.  This group represents over 3,700 nutrient management plans, manure management plans, and comprehensive nutrient management plans.

Outcome: 
An in-depth phone survey of a random representative sample of participants was conducted followed by on-line survey of all participants.  Surveyed participants (72) indicated making changes to plans to meet nutrient management standards.  Number of plans needing changes ranged between 10 to 60 percent based on individual fields included in the plan.  Recommended changes, on an individual field basis, include modifications to the tillage practices, no manure application, implementation of buffer strips, and changes to crop rotations.  No-till farming practices, terraces, and contour farming have also been recommended to reduce nutrient transport associated with soil loss.  Surveyed participants indicated between 30 to 100 percent of recommended changes have been followed by producers on individual plan and affected field basis.
