| Property | It is soluble in water and alcohol. Its water solubility is faintly alkaline. It decomposes when heated over fusing point. Under high temperature, it can undergo a condensation reaction and form biuret, triuret and polyhydrocyanic acid. |
Urea, offered by Guangzhou Zhifan Chemical Co., Ltd., is a multi-functional compound with diverse applications. In agriculture, it serves as a vital nitrogen fertilizer, enhancing plant growth and improving crop yield and quality. Additionally, it can be used as a foliar fertilizer, directly nourishing plant leaves.
Within the industrial sector, urea acts as a key chemical raw material, facilitating the production of plastics, dyes, fibers, and adhesives. Moreover, it can be transformed into a urea aqueous solution, ideal for applications like coolant, antifreeze, and fire extinguishing.
Medical professionals utilize urea in the creation of drugs like urea ointment and injection, effectively treating skin diseases and renal failure. Furthermore, urea plays a crucial role as a reagent in biochemical experiments and diagnostics.
Explore the versatility of urea from Guangzhou Zhifan Chemical Co., Ltd. and unlock its numerous benefits across agriculture, industry, and medical fields.
Avoid use as seed fertilizer: Urea will produce a small amount of biuret during the production process. When the biuret content exceeds 2%, it will poison seeds and seedlings, affecting seed germination and seedling growth.
Avoid mixing with alkaline fertilizers: When urea is mixed with alkaline fertilizers such as plant ash, lime, phosphate fertilizers, etc., chemical reactions will occur, resulting in loss of fertilizer efficiency.
Avoid using too much: Urea has a high nitrogen content. Generally, the dosage per mu is 5 to 15 kilograms in dry fields and 15 to 20 kilograms in paddy fields. Excessive use not only causes waste but may also cause damage to crops.
Avoid shallow application: Urea should be applied next to the seedlings or in a trench at a depth of about 10 to 15 cm to improve fertilizer efficiency.
Avoid watering immediately after application: Irrigation immediately after application or application on dry land before heavy rain, urea will dissolve in the water and be lost. Generally, watering should be done 2 to 3 days after application in summer and autumn, and 7 to 8 days after application in winter and spring.
Avoid surface application: When urea is applied on the surface, most of it will evaporate during the ammoniation process, and the actual utilization rate is only about 30%. The correct method is to apply mulching soil deeply so that the fertilizer is in a moist soil layer, which is conducive to the effectiveness of the fertilizer.
