UniSlow 21 is designed to increase fertilizer efficiency and reduce leaching and runoff. Thanks to the nitrogen inhibitor it contains; it minimizes nitrogen losses by delaying the conversion of ammonium nitrogen (NH4+) to nitrate nitrogen (NO3-) for 6 to 10 weeks, depending on your soil temperature. Thus, more nitrogen becomes available for your product, providing maximum benefit while minimizing the environmental impact.The plant, which is fed with the ammonium form of nitrogen for a longer period of time, instantly lowers the pH in the root area (pH around the granule remains below 7), creating an environment that facilitates the uptake of other nutrients. Losses caused by washing with rain and irrigation water are minimal in UniSlow N21.

It is a slow-release, 100% water-soluble ammonium nitrogen in crystal form with DCD inhibitor that can be applied with sprinkler and drip irrigation systems in all plant patterns. Apart from 21% ammonium nitrogen, it also contains sulfur. It regulates soil pH values due to ammonium nitrogen and available sulfur.

It can be used in all fruit and vegetable farming, especially citrus fruits and those that require ammonium nitrogen. When used with drip irrigation systems; it should be applied at 3–5 kg/da depending on the plant type and development status.
