Project: Establishment and Monitoring of Saturated Buffers within High–Priority HUC–12 Watersheds
A multidisciplinary team of scientists led by Antonio Mallarino, a professor of agronomy at Iowa State University, has completed two years of a long-term field study to better understand the impacts of cover crops on nutrient loss with surface runoff.
A 2016 report of Iowa’s water monitoring efforts for nutrients highlights both the complexity and long-term value of evaluating nutrient levels in Iowa’s lakes, streams and rivers. Developed jointly by the Iowa Department of Agriculture and Land Stewardship and Iowa Department of Natural Resources, with the support of Iowa State University and the University of Iowa IIHR—Hydroscience and Engineering Center, the report is the first of its kind in Iowa and includes a comprehensive list of surface water monitoring efforts specific to nutrients.
AMES, Iowa — As an undergraduate, Michael Castellano spent one summer on a New Mexico ranch doing environmental science research. He was inspired by the landowner’s implementation of a grass banking system.
Two Iowa State University professors have been appointed to serve on the Agricultural Science Committee of the Environmental Protection Agency’s Science Advisory Board.
A better economical understanding of the value of water is in progress at Iowa State University after an $800,000 award was given to researchers at The Center for Agricultural and Rural Development by the U.S. Environmental Protection Agency (EPA.)
Iowa State University personnel have designed an online simulation that allows students and adults to experiment with how land-use practices can affect the health of a watershed.
Iowa State University researchers are seeking feedback from Iowa farmers willing to test an early online version of a tool to better understan
A new study from an Iowa State University agronomist shows that an increase in perennial bioenergy grasses throughout the Corn Belt would lead to a significant reduction in nitrogen moving down the Mississippi River and into the Gulf of Mexico.
Eleven land-grant institutions and partner organizations are working together to improve farm drainage in order to reduce the contamination of surrounding land and water. The underground drainage systems that channel water off of fields are also prone to diverting crop fertilizers and pesticides. In 2009, researchers formed the “Project NCERA-217: Drainage Design and Management Practices to Improve Water Quality.”
Iowa State University is beginning a state-funded project in partnership with the Iowa Nutrient Research and Education Council (INREC) to explore how to measure Iowa farmers’ progress in reducing nutrients moving from fields into rivers and streams.
Practices and strategies that minimize nutrient loss and soil erosion and increase soil health can have positive impacts on water quality while maintaining and improving productivity. The 2015 Iowa Farm and Rural Life Poll found that many farmers have increased their use of key practices in recent years.
AMES, Iowa — Cover crops offer a valuable tool for farmers to reduce nutrient loss and help ensure clean water in Iowa waterways. But some farmers have reported that planting winter rye as a cover crop may reduce corn yield.
A team of researchers at Iowa State University is investigating why there may be an occasional decrease in corn yield after planting winter rye.
The Iowa Nutrient Research Center at Iowa State University has funded 11 new projects related to water quality.
Researchers from Iowa State, the University of Iowa and the University of Northern Iowa will collaborate on the projects with those from the U.S. Department of Agriculture, Iowa Department of Natural Resources, the Iowa Soybean Association, The Nature Conservancy and AgSolver Inc. This is the third year the center has funded research.
Wetlands targeted to intercept water from heavily tiled cropland in Iowa have been called “heavy lifters” in the effort to carry Iowa’s nutrient reduction strategy. These wetlands can both improve water quality and provide habitat for wildlife.
Dean Lemke’s interest in environmental stewardship began as a young boy on the family farm.
“Dad repeatedly made the point we have to leave the land and natural resources for future generations in better condition than when we got them,” he says.
Ten years ago, farmers in northeast Iowa banded together to improve their watershed. Now it’s being called a model for improving water quality across Iowa and the nation.
Tom Isenhart is a catalyst for getting research results to the people who need it most. The professor of natural resource ecology and management has built partnerships with landowners and farmers for decades all with the same goal to improve water quality.
Returning a small part of Iowa farmland to prairie is bringing a huge number of benefits according to Iowa State University research. The STRIPS project—Science-based Trials of Rowcrops Integrated with Prairie Strips—has proven the benefits of placing prairie strips in Iowa cropland.
