urea 46 nitrogen granular nitrogen fertilizer

Descriptions of urea 46 nitrogen granular nitrogen fertilizer:

   Urea is a kind of white prilled crystal. Urea is mainly used as fertilizer,and also used as industrial materials in synthetic industry and other fields, such as medicine, dye, textile, detonator, oil refining and printing. 

Specification of urea 46 nitrogen granular nitrogen fertilizer:

Granular Urea/Carbamide

Prilled Urea/Carbamide

Characteristics of urea 46 nitrogen granular nitrogen fertilizer:

1.It is colorless or white needle or rodlike crystal. Its industrial or agricultural product is white with reddish odorless and tasteless solid particle.

2.It can melt in water and alcohol but not in ethyl ether and chloroform. It is slightly alkaline and it will react with acid and produce salt. It has hydrolytic action and it can also have condensation reaction in high temperature and produce biuret, triuret, and cyanuric acid.

3.It will break down when heated to 160℃ to produce ammonia gas which then becomes cyanic acid. Urea contains 46% N and it is the solid nitrogen that has the most nitrogen content.

4.It can be the raw material of producing melamine, formaldehyde resin, hydrazine hydrate, tetracycline, vat brown BR, phthalocyanine blue B, phthalocyanine blue Bx, aginomoto and many other products.

5.It can improve the leaf nitrogen content of apple tree, accelerate the new shoot growth, and inhibit flower bud differentiation. Thus it can adjust the flower number of apple tree in different years.

6.1.5%-2% urea in booting stage and initial heading stage (20% heading) will increase the outcrossing rate of hybrid rice as well as its produced amount and propagation quantity of sterile series. Meanwhile, the plant height won’t be affected.

7. Mixture of urea, washing powder, and fresh water in the ratio 4:1:400 can keep the fruit tree, vegetables, and cotton away from aphid, red spider, cabbage caterpillar and other pests. Its insecticidal efficacy can be up to 90%.

8.Urea can be combined with Fe²⁺ in the form of complex to become EDTA-Fe. This kind of organic ferric fertilizer has low price but good of iron deficiency green loss prevention and treatment effect.

9.Urea has good dye solubility property, mild reducibility/ inoxidizability, and excellent hygroscopicity, thus it can be used as dye solvent/hygroscopic agent/ viscose fiber swelling agent and resin finishing agent by textile industry .

Advantage in agriculture:

1.Nitrogen provides N for NPK. it provides an equal balance of nitrogen and sulphur, meets 

   short term sulphur deficits of crops, pastures and other plants.

2.Fast release, quick acting, long-term effect. 

3.More efficiency than urea, ammonium bicarbonate, ammonium chloride,ammonium nitrate.

4.Can be readily blended with other fertilizers. It has the desirable agronomic features of 

    being a source of both nitrogen and sulphur. 

5.Comprehensive nutrition , supply micro elements which the plant need.

6.Specially add ZTDH rooting powder, increase and protect the root, improve quality of crops

7.Specially add polymeric acid, improve utilization about 30%-40%.

8.Nitrogen fertilizer can make crops thrive and improve fruit quality and yield and strengthen

   resistance to disaster, can be used for common soil and plant in basic fertilizer, additional 

   fertilizer and seed manure. 

Usage of urea 46 nitrogen granular nitrogen fertilizer:

1. Used as fertilizer, applied to a variety soil and crops.

2. Used in textile,leather,medicine and so on.

3. Used as the raw material of BLENDING NPK

Application of urea 46 nitrogen granular nitrogen fertilizer:

  Mostly used as nitrogen fertilizer in agriculture, it’s a neutral organic fertilizer, also can be used in the production of a variety of compound fertilizer. There is no harmful residues in the soil. No bad influence for long term application.
