How ESN Works
ESN Feeds Your Crops All Season Long
ESN® is 44% nitrogen, it is comprised of urea contained within a flexible polymer coating. This coating protects the nitrogen from loss mechanisms and releases nitrogen in response to soil temperature. ESN gives crops all the nitrogen they need, when they need it.
How ESN Releases nitrogen
ESN’s polymer membrane allows moisture to diffuse into the granule, creating a nitrogen solution. The solution moves out through the membrane at a rate that is controlled by soil temperature and matches the nitrogen demand of the growing crop.
