Urea, offered by Guangzhou Zhifan Chemical Co., Ltd., is a versatile compound with a wide range of applications. In agriculture, it serves as a vital nitrogen fertilizer, promoting plant growth and enhancing crop yield and quality. Additionally, it can be used as a foliar fertilizer, delivering nutrients directly to plant leaves.
Within the industry, urea acts as a crucial chemical raw material, facilitating the production of various products like plastics, dyes, fibers, and adhesives. It can also be utilized to create urea aqueous solutions for applications such as coolant, antifreeze, and fire extinguishing agents.
Medical applications of urea include the production of drugs like urea ointment and injections, which are used to treat skin diseases and renal failure. Furthermore, urea serves as a valuable reagent in biochemical experiments and diagnostic procedures.
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.
