Agrium Advanced Technologies (AAT) agronomists recently hosted the first annual Research and Demonstration Tour created to increase awareness of ESN Smart Nitrogen as a part of a nitrogen management program. Tour stops included Mississippi State University (MSU) in Stoneville, Miss.; an ag retailer in Drew, Miss.; and the University of Arkansas Lon Mann Cotton Research Station (LMCRS) in Marianna, Ark.
Participants were able to walk through the research plots and speak with the scientists conducting the various studies. Researchers at MSU are testing ESN on a variety of crops, including cotton, corn and soybeans, and monitoring effectiveness under different conditions. Although yield results for this year’s crops are not yet available, ESN-fertilized crops appear to be more vigorous. For example, ESN-fertilized corn ears were larger and more filled.
The research in Stoneville has been conducted since 2011 by Bobby Golden, Ph.D., who also studied ESN at the University of Arkansas as a Ph.D. student. At Stoneville, he has been studying ESN use in cotton, corn and soybeans - comparing ESN with competitor products. At this location, participants saw first-hand how changes in rates, timing of application, and blends can affect crop performance.
“In general, over the last couple years, ESN has performed well on cotton and corn in Mississippi. On corn, ESN applied at planting provides a yield increase when compared with top-dressed urea,” says Golden.
The LMCRS in Marianna, Ark., was the last stop on the tour. Morteza Mozaffari, Ph.D., shared his experience with ESN on corn and cotton. Corn fertilized with ESN has produced significantly higher yields than conventional urea during the past two years. ESN-treated plots were visibly greener and appeared to have greater yield potential than standard nitrogen sources.
“The results from the past two years suggest that pre-plant, incorporated ESN is a suitable alternative to standard pre-plant urea,” says Mozaffari.
