Print Friendly, PDF & Email

A fertilizer used to provide nitrogen for crop production. The product, stored under high pressure as a liquid, changes state during application and is injected into soil as a gas. It is popular due to the fact that it is composed of 82 percent nitrogen compared to other nitrogen fertilizers such as urea that contain only 46% nitrogen and ammonium nitrate with 30-33% nitrogen content.
