Mississippi soybeans get a boost from Smart Nitrogen

Bobby Golden

Trials of ESN use on soybeans have shown an average yield increase of 6%, according to Dr. Bobby Golden of Mississippi State University’s Delta Research and Extension Centre.

“This is the third year of soybean trials that we’ve been working on here, specifically looking at application timings – V4 and R1 – to see if we can boost the already high yield potential in the soybean,” Dr. Golden explained during a recent tour of plot trials at the Delta Research and Centre in Stoneville, MS. “We’re determining an appropriate N rate – if one exists – to get us to the next level. Our current results, with the preliminary year and then one full year of trials, we’re averaging about a 6% yield increase when we apply at least 40 units of (ESN) nitrogen.”

Crop Safety Aspect

Dr. Golden said beyond potential for yield increases, ESN has been shown to provide crop safety attributes in areas where urea is typically applied in a top dress.

“We see, because of our high humidity and leaf wetness, a lot of foliar injury from top dress urea applications on corn when the whorl is open. We’ve seen a little bit to a great deal better results in the crop safety when we use ESN over top depending on those environmental conditions,” he explained. “Under the wet conditions here in the midsouth is where we see ESN perform the best.”

Researching new and better ways to grow crops keeps Dr. Golden motivated as a scientist, but it’s when he gets to help a farmer solve a problem that he sees firsthand the impact of his work.

“As a scientist you’re always inquisitive, you always want to find the next thing,” he said. “But what I get the most satisfaction is when we can go to a guy’s farm who might have a problem … identify that problem, fix it, and put dollars back in his pocket.”
