Product Description
Urea is an organic nitrogen fertilizer with an extremely high nitrogen content. It is also one of the most widely used and largest - consumption nitrogen fertilizers in current agricultural production. Its chemical name is carbamide, and its chemical formula is CO(NH2)2.
The nitrogen content of urea is as high as 46% (it has the highest nitrogen content among all solid nitrogen fertilizers). The nitrogen element exists in the amide form (non - ionic state) and needs to be transformed by soil microorganisms before it can be absorbed by crops.

Product Advantages
-
High nitrogen content: Urea contains approximately 46% nitrogen and is one of the solid nitrogen fertilizers with the highest nitrogen content. It can meet the nitrogen needs of plants with a relatively small amount, reducing transportation and storage costs.
-
Diverse application methods: It can be spread as granular fertilizer, or prepared into liquid solutions for irrigation or foliar spraying, adapting to different planting systems and application methods.
-
Low cost: Compared with other nitrogen fertilizers, the cost per unit of nitrogen in urea is usually lower, making it an affordable choice for farmers who pursue input efficiency.
-
Long - lasting fertilizer effect: After urea is applied to the soil, it needs to be decomposed and converted into ammonium - nitrogen by microorganisms before being absorbed by crops. The fertilizer effect is relatively slow, but the duration is long. It can provide a continuous supply of nitrogen to crops, helping to maintain the uniform growth of crops.
-
Rapid foliar absorption: Due to its high solubility and the ability to penetrate the leaf cuticle, it can be quickly absorbed by plants through foliar spraying, and can correct the nitrogen deficiency problem of crops in a short period.
-
Friendly to soil: Urea is a physiologically neutral fertilizer. It does not leave harmful substances in the soil. Long - term application has no destructive effect on the soil. The carbonic acid it contains also helps with carbon assimilation and the dissolution of insoluble phosphates for crop utilization.
Application
Soil types: It is especially suitable for sandy soil and can also be used for various soil types such as saline - alkaline soil. It has a certain effect on improving the soil structure and fertility of saline - alkaline land.
Crop types: It significantly increases the yield of rice under intermittent irrigation conditions. It is also applicable to various crops such as corn, sugarcane, vegetables, fruits, and fruit trees. For sulfur - deficient areas and sulfur - sensitive crops like cruciferous crops, it can better meet their growth requirements.
All crops that require more nitrogen are particularly suitable for:
-
leafy vegetables (such as lettuce and spinach, promoting thick leaves);
-
grain crops (such as wheat, rice, and corn, improving tillering and grain filling);
-
fruit trees (such as apples and citrus, applying nitrogen during the flowering and fruit expansion periods to reduce flower and fruit drop);
-
flowers (promoting lush foliage and more blooms).
Precautions
-
Avoid applying it in combination with alkaline fertilizers (such as plant ash and ammonium bicarbonate) (this will lead to ammonia volatilization and loss);
-
Avoid "over - application": It easily causes excessive growth of crops (weak and thin stems, prone to lodging), an increase in pests and diseases (such as aphids), and may also cause the accumulation of soil nitrate nitrogen (polluting groundwater);
-
Stop applying it 15 - 20 days before the harvest of leafy vegetables (to reduce nitrate residues).
