Corn growers seeking to increase nitrogen uptake typically adjust aspects of fertilizer application. However, a recent study shows the crop takes up the majority of its nitrogen from sources naturally occurring in the soil.
Kelsey Griesheim with North Dakota State University spoke with RFD-TV’s own Susanne Alexander to give us a closer look at the research. which found that corn crops glean about 67 percent of nitrogen from soil.
“More fertilizer in the crop means less fertilizer left in the soil,” Griesheim said. “I hope producers realize the magnitude of these numbers.”
