Urea Ammonium Nitrate

32% Urea Ammonium Nitrate Solution

32% Urea Ammonium Nitrate (UAN) Solution is an effective source of Nitrogen used in a variety of cropping systems.

32% UAN is a liquid nitrogen fertilizer solution composed of urea and ammonium nitrate. A portion of the Nitrogen is available in two forms, the nitrate form (NO3-) which is immediately available for plant uptake, and in the form of Ammonium (NH4+), which is also assimilated directly by most plants, but, is rapidly oxidized by soil bacteria to form NO3-. The rest of the solution is comprised of urea, and is hydrolyzed by soil enzymes to form NH4+, which is subsequently transformed to NO3- in most soil conditions. As a result, this solution provides both fast acting and long lasting plant food through its three forms of nitrogen.

Due to its chemical properties, 32% UAN Solution is compatible with many other nutrients and agricultural products. It is frequently mixed with solutions containing phosphorus and potassium as well as other essential plant nutrients. This solution is well adapted for a variety of application processes, including: soil injections, foliar sprays and irrigation systems.
