NEW TECHNOLOGY DEVELOPMENT & ENVIRONMENTAL VALIDATION
INREC collaborates with numerous partners to foster innovation of new technologies and expansion of science-based options for meeting water quality goals. Science leadership is provided by ISU.
Evaluation of Surrogate Measures for Nitrate
Assessment of Impact of Rainfall on Tile Drainage and Nitrate
Assessment of Point and Nonpoint Source Nutrient Loading Patterns
EDUCATION & OUTREACH
INREC believes that the agricultural community is a vast source of knowledge and opportunity. It is a goal of INREC to enhance learning and educational opportunities for and within agriculture. By this INREC will provide increased outreach and training opportunities through workshops, field days, and informational materials. We believe this will help ag retailers and crop advisers with advising farmer decisions regarding environmental technologies and practices.
ENVIRONMENTAL PROGRESS MEASUREMENT
Iowa's official system for measuring Nutrient Reduction Strategy progress is the result of an INREC collaboration with agronomy retailers, Certified Crop Advisors (CCA), and Iowa State University. The progress measurement system utilizes a first-of-its-kind system using ag retailer sales data and farm records to track and demonstrate environmental progress being made by Iowa farmers.

RESOURCES
Comprehensive list of INREC projects. Includes brief descriptions and numerous links to additional information about the various projects we have underway or completed.
The Iowa Nutrient Reduction Strategy is a science and technology-based framework to assess and reduce nutrients to Iowa waters and the Gulf of Mexico. It is designed to direct efforts to reduce nutrients in surface water from both point and nonpoint sources in a scientific, reasonable and cost effective manner.
Iowa DNR Report on Challenges of Using Water Quality Monitoring as Progress Metric
State development and implementation of nutrient reduction strategies are a major focus of the Hypoxia Task Force (HTF).
4R Plus involves using precise 4R nutrient management and conservation practices to provide nutrients when the crop needs them and to enhance soil health and improve water quality.
Iowa farmers are proud of the progress their conservation efforts are making. See the results for yourself!
