UAN

Specification:

Property:

Solutions of UAN are widely used as a source ofN for plant nutrition. The NO3 portion(25% of the total N) is immediatelyavailable for plant uptake. The NH4+fraction (25% of the total N) can also beassimilated directly by most plants, but id rapidly oxidized by soil bacteriato form NO3-. The remaining urea portion (50% of the total N) is hydrolyzed bysoil enzymes to form NH4+, which is subsequently transformed to NO3 inmost soil conditions.

Application:

UAN solutions arecommonly injected into the soil beneath the surface, sprayed onto the soilsurface, dribbled as a band onto the surface, added to irrigation water, orsprayed onto plant leaves as a source of foliar nutrition. However, UAN maydamage foliage if sprayed onto plant leaves as a source of foliar nutrition.However, UAN may damage foliage if sprayed directly on some plants, so dilutionwith water may be needed.

1). Applied ingreenhouse and lareg-area farmland, it improves the soil and granulates thesoil making it anti-caking.

2). When employedin industrial crops, flowers, fryits and vegetables, it extends florescence,spurs the root, the stem and the leaf to grow normally, guarantees fruitsin gay colors and increases carbohydrate contents in fruits.

3). It is ahigh-efficiency environmental prodtection greening fertilizer.
