In 2016, IFB and GROWMARK announced a new initiative called 4R4U to demonstrate and investigate 4R nutrient stewardship practices at the local level. This statewide partnership, which also includes CFBs and the FS companies, is a pilot program to bring added use, awareness, and knowledge on nutrient stewardship through the 4R approach. Local test plots will be used to compare the effects of a range of practices on nutrient stewardship. Each of the 11 local partnerships depends on the cooperation and innovation of farmers and agricultural retailers. Practices that are being demonstrated and investigated on the local level include N-rates, multiple nitrogen applications, stabilizers, no-till planting, cover crops, and soil samples.
