More than 90% of world industrial production of urea is destined for use as a nitrogen-release fertilizer. Urea has the highest nitrogen content of all solid nitrogenous fertilizers in common use. Therefore, it has the lowest transportation costs per unit of nitrogen nutrient.
Urea fertilizer is a popular and widely used nitrogen-based fertilizer that contains a high concentration of nitrogen. It is commonly used in agriculture to promote the growth of crops and increase their yield. Urea fertilizer is a white crystalline substance that is water-soluble and easy to handle.
1. High Nitrogen Content: Urea fertilizer has a high nitrogen content, which makes it an effective fertilizer for promoting plant growth and increasing crop yields.
2. Cost-Effective: Urea fertilizer for plant is relatively inexpensive compared to other types of fertilizers, which makes it a popular choice for farmers and gardeners.
3. Easy to Handle: Corp urea fertilizer is easy to handle and can be applied using conventional fertilization equipment.
4. Versatile: Urea fertilizer from Sanyuanjiuqi can be used on a wide range of crops, including cereals, oilseeds, vegetables, and fruits.
Urea is usually spread at rates of between 40 and 300 kg/ha but rates vary. Smaller applications incur lower losses due to leaching. During summer, urea is often spread just before or during rain to minimize losses from volatilization (process wherein nitrogen is lost to the atmosphere as ammonia gas). Urea is not compatible with other fertilizers.
Because of the high nitrogen concentration in urea, it is very important to achieve an even spread. The application equipment must be correctly calibrated and properly used. Drilling must not occur on contact with or close to seed, due to the risk of germination damage. Urea dissolves in water for application as a spray or through irrigation systems.
In grain and cotton crops, urea is often applied at the time of the last cultivation before planting. In high rainfall areas and on sandy soils (where nitrogen can be lost through leaching) and where good in-season rainfall is expected, urea can be side- or top-dressed during the growing season. Top-dressing is also popular on pasture and forage crops. In cultivating sugarcane, urea is side-dressed after planting, and applied to each ratoon crop.
In irrigated crops, urea can be applied dry to the soil, or dissolved and applied through the irrigation water. Urea will dissolve in its own weight in water, but it becomes increasingly difficult to dissolve as the concentration increases. Dissolving urea in water is endothermic, causing the temperature of the solution to fall when urea dissolves.
As a practical guide, when preparing urea solutions for fertigation (injection into irrigation lines), dissolve no more than 3 gurea per 1 L water.
In foliar sprays, urea concentrations of 0.5% – 2.0% are often used in horticultural crops. Low-biuret grades of urea are often indicated.
Urea absorbs moisture from the atmosphere and therefore is typically stored either in closed/sealed bags on pallets or, if stored in bulk, under cover with a tarpaulin. As with most solid fertilizers, storage in a cool, dry, well-ventilated area is recommended.
Overdose or placing Urea near seed is harmful.

1. Determine the Nitrogen Requirement: Before applying urea fertilizer, it is important to determine the nitrogen requirement of the crop. This can be done by conducting a soil test or consulting with an agricultural expert.
2. Apply at the Right Time: Urea fertilizer should be applied at the right time to ensure maximum effectiveness. It is generally recommended to apply urea fertilizer in the early morning or late afternoon when temperatures are cool.
3. Spread the Fertilizer Evenly: Plant urea fertilizer should be spread evenly across the soil to ensure uniform distribution. This can be done using conventional fertilization equipment such as a broadcast spreader or a drop spreader.
4. Water the Soil: After applying urea fertilizer, it is important to water the soil to help the fertilizer penetrate into the root zone. This will ensure maximum absorption and utilization by the plants.
