Our Original Purpose

What is the Iowa Nutrient Reduction Strategy?

The Iowa Nutrient Reduction Strategy is a science and technology-based framework developed to assess and reduce nutrients in Iowa waterways and the Gulf of Mexico. This strategy was designed to direct efforts to reduce nutrients in surface water from both point and nonpoint sources in a scientific, reasonable and cost-effective manner. INREC is proud to support these efforts.

The Primary Project

The Survey Process

Each year, 150 ag retail locations are selected out of the approximately 600 in Iowa at random to complete the Nutrient Reduction Strategy Survey. With this survey, retailers are asked to identify ten customers based on the random selection criteria provided and complete the survey of in-field conservation practices. Responses are evaluated by the Iowa State University Center for Survey Statistics & Methodology to extrapolate for statewide adoption of conservation practices.

Surveys Completed Annually

Since every acre of every field in Iowa has some connection to an agricultural retailer, this survey of retailer records is the best data set we have to accurately assess progress.
