ESN Smart Nitrogen is a controlled-release fertilizer technology to deliver nitrogen as growing crops demand it. It's one of the optimum ways for growers to optimize their nitrogen investment.
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.
The 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.
ESN, therefore, gives crops all the nitrogen they need when they require it.
