Product Feature:
Solutions of UAN are widely used as a source of N for plant nutrition. The NO3 portion(25% of the total N) is immediately available for plant uptake. The NH4+fraction (25% of the total N) can also be assimilated directly by most plants, but id rapidly oxidized by soil bacteria to form NO3-. The remaining urea portion (50% of the total N) is hydrolyzed by soil enzymes to form NH4+, which is subsequently transformed to NO3 in most soil conditions.
Application:
UAN solutions are commonly injected into the soil beneath the surface, sprayed onto the soil surface, dribbled as a band onto the surface, added to irrigation water, or sprayed onto plant leaves as a source of foliar nutrition. However, UAN may damage foliage if sprayed onto plant leaves as a source of foliar nutrition. However, UAN may damage foliage if sprayed directly on some plants, so dilution with water may be needed.
1). Applied in greenhouse and lareg-area farmland, it improves the soil and granulates the soil making it anti-caking.
2). When employed in industrial crops, flowers, fryits and vegetables, it extends florescence, spurs the root, the stem and the leaf to grow normally, guarantees fruits in gay colors and increases carbohydrate contents in fruits.
3). It is a high-efficiency environmental prodtection greening fertilizer.
