How ESN Works

How enhanced efficiency fertilizers work

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.
