Weather and field conditions can present challenges for farmers who are attempting to apply nitrogen in the spring. However, a new trial in Michigan indicates the flexibility of ESN Smart Nitrogen can help farmers making applications when field conditions and weather are less than optimal.
The trial, conducted in Lansing, Mich., by Kurt Steinke and Andrew Chomas of Michigan State University, studied fertilization programs on sandy loam soils. Fertilization programs for corn in northern regions typically require one to two passes, usually with some combination of nitrogen applied before planting followed by a post-emergence sidedress application.
ESN can be used as part of a typical two-pass program or as a single application to apply all of the nitrogen needed for the entire growing season in one application. "Farmers don’t have to choose between a preplant or topdress or sidedress," says Matt Clover, agronomist for Agrium Advanced Technologies.
"With ESN, farmers can combine the nitrogen loss protection of sidedress or topdress ESN applications with the immediate nitrogen availability of a preplant application of conventional fertilizer."
