Now farmers and advisors in all 12 Corn Belt states can use the free Corn-Split N decision support tool, developed by the USDA-funded Useful to Useful climate initiative. The tool helps farmers and advisors manage nitrogen application for efficiency and profit. Corn yield response data from seven new states, together with statistical modeling of days suitable for field work in those states, has recently been added.
Farmers in Illinois, Iowa, Indiana, Missouri, Kansas, Wisconsin, Minnesota, South Dakota, North Dakota, Nebraska, Ohio and Michigan can get customized results based on their planting and fertilization schedule, local costs and available equipment. A summarized fieldwork table and crop calendar makes it easy for farmers to see how schedule adjustments might affect their ability to fertilize on time.
