Michael Brooks is an ESN retailer in Minnesota and finds that ESN provides a good ROI to a lot of his growers. He compares the slow release of ESN to spoon-feeding nitrogen to the crops, saying the more you spoon-feed nitrogen, the better off that plant will be and the more yield potential you can gain. Although more expensive than straight nitrogen, ESN will offer a better ROI in the long run because of its slow release and ease of application. In a wet climate ESN will withstand the conditions and help deliver nitrogen to plants throughout the season. Using ESN also helps to alleviate nitrogen loss while being kind to the environment.
