產品描述

UAN 32% Solution is a nitrogen fertilizer solution composed of urea 和 ammonium nitrate.

1.Fully water-soluble, no impurities, the use of various methods, can be foliar spray, drip irrigation and flushing, and can be diluted with other fertilizers, pesticides at the same time, saving time,and labor
2.High utilization rate: the utilization rate is as high as 90%, which is 4 times that of traditional urea, effectively reducing nitrogen loss
3.Polymorphic nitrogen sources: nitrate nitrogen, ammonium nitrogen, amide nitrogen three forms of nitrogen complete, both quick and durable, to meet the nutrient needs of different growth stages of crops, to ensure balanced and durable absorption of nutrients, high fertilizer efficiency

UAN 32% Solution  can be used on just about all crops. It is widely used for side-dressing cotton,  vegetables, corn, beets and other crops. Sprinkler applied UAN 32% Solution is used for tree crops such as almonds, for cereal grains, potatoes and for manyother crops.  

應用

1.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 is 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.
2.Solutions of UAN are extremely versatile as a source of plant nutrition. Due to its chemical properties, UAN is compatible with many other nutrients and agricultural chemicals, and is frequently mixed with solutions containing P, K, and other essential plant nutrients. Fluid fertilizers can be blended to precisely meet the specific needs of a soil or crop.
3.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 directly on some plants, so dilution with water may be needed.
4.UAN solution, produced by combining urea, nitric acid, and ammonia, is a liquid fertilizer product with a nitrogen content that typically ranges from 28 percent to 32 percent. UAN can be applied more uniformly than non-liquid forms of fertilizer. It can be mixed with herbicides, pesticides, and other nutrients, permitting farmers to reduce costs by applying several materials simultaneously rather than making several separate applications.
