About Iowa S.T.A.R.

  • S.T.A.R. is a FREE tool to assist farm operators and landowners in evaluating their nutrient and soil management practices on individual fields. The ultimate objective is to meet the goals of the Iowa Nutrient Reduction Strategy (NRS).

  • The S.T.A.R. evaluation program assigns points to each cropping, tillage, nutrient application, and soil conservation activity on individual fields. The S.T.A.R. Science Committee, comprised of agricultural experts and university researchers, reviews practices to determine the points and ranking system. Higher point values are assigned to those practices that align best with the NRS science assessment and goals and will be updated annually to reflect the most current research. The star rating for a field will be from 1 to 5 stars.
