Iowa Nutrient Research Center invites new water quality research proposals

March 28, 2022

AMES, Iowa- The Iowa Nutrient Research Center is accepting new proposals for research projects designed to reduce nitrate and phosphorus in Iowa’s water.

The center invites proposals for water quality projects that will benefit farmers, landowners, agribusinesses, policy makers and communities. Proposed research projects must be led by Iowa State University, the University of Iowa or the University of Northern Iowa, as dictated by the center’s legislative mandate. Other research partners may include organizations, agencies, businesses, other Iowa colleges and landowners.

“This year’s RFP is informed by two sessions held in February 2022 that included diverse stakeholders,” said INRC Director Matt Helmers. “We have tried to represent the top priorities that came out of a broad set of research ideas compiled by those who attended the meetings.”

This year the center will focus funding consideration on five areas of research:

  1. Integrated crop and livestock systems research
  2. Sociological water quality research
  3. In-stream processes and scales of N and P yields
  4. Co-benefits of nutrient reduction practices
  5. New technologies

“As in the past, depending on the proposals we received, we will also consider sound research projects that don’t fit the priority areas of research, especially those that address critical missing links that build upon past INRC-funded research,” said Helmers.

Potential applicants are encouraged to view the full 2022 Request for Proposals (PDF) for additional details about the priority topics and application instructions. Projects can last up to two years. Investigators that were funded in 2021 for multiple years do not have to reapply.

Proposals are due by May 10, 2022, for projects that would begin August 15, 2022. Award decisions will be made in late June.

Questions about the request for proposals should be directed to Malcolm Robertson, the center’s program specialist, 515-294-5692, or, or Matt Helmers, at
