By implementing 4R nutrient stewardship practices, you optimize the nutrients you apply to maximize plant uptake and minimize field losses. Using the 4Rs allows you to keep the nutrients in the root zone and available when the crop needs them the most during the growing season.
Watch this video to learn more about 4R nutrient stewardship practices for your farm that will improve water quality and soil health.
The right time for nutrient stewardship is right now. Get more information about 4R nutrient stewardship best practices.
4R Plus educational modules developed by The Fertilizer Institute, Natural Resources Conservation Service, International Plant Nutrition Institute and Iowa State University. There are CCA CEUs tied to each module.
"I’ve been using the 4Rs for some time. I’ve increased my yields by utilizing nutrients more efficiently. I’m able to reduce nutrient runoff by applying them when the crop is ready to uptake them. I also use split-applied nitrogen because I have many soil types and some cannot hold a large amount of nutrient at once. Corn yields have increased by 25–30 bushels/acre using the 4Rs. In 2015, one field averaged above 250 bushels for the first time."

4R Plus practices improve soil health and water quality, says Shawn Richmond, director of environmental technology, Agribusiness Association of Iowa. Learn why he says it’s important for all farmers to understand the goals set out by the Iowa Nutrient Reduction Strategy.
Emily Doyle, a precision ag specialist and farmer from Tama County, Iowa, says using the 4Rs of nutrient stewardship – right place, right source, right rate, right time and right place – allows farmers to keep nutrients in the root zone and available when the crop needs it the most during the growing season.
