What is urea nitrogen fertilizer?

Urea nitrogen fertilizer (also known as Urea fertilizer) is an organic nitrogen fertilizer with the highest N ratio. This is an organic compound of nitrogen, carbon, oxygen, and hydrogen.

Urea protein usually contains 44-48% elemental N. With high N content along with many other benefits, Urea fertilizer is very popular with farmers and used in agriculture. This type of fertilizer accounts for 59% of the total nitrogen fertilizers produced in countries around the world.

URE fertilizer is suitable on many types of soil with many different crops, has high economic efficiency in agriculture.

Physical properties of Urea

Urea fertilizer is recognized in the form of white crystals, round granules, easily soluble in water, strongly hygroscopic (disadvantage of this fertilizer). However, the protein shell has been covered with moisture-proof layer, so it is easy to store and transport, and is used a lot in agricultural production.

Application of UREA fertilizer to plants.

1. In agriculture

– Urea fertilizer provides high N content for plant growth.

– Urea, after being absorbed into the soil or plants, the enzyme will quickly convert it back to NH3 form, called hydrolysis. Hydrolysis takes place very quickly, usually within 7 days after application.

– A small amount of N source directly from Urea can be utilized by plants.

– Urea N with hydrolysis causes slightly alkaline, so it has the ability to reduce acidity but not high in a short time and eventually causes a mild sour reaction. Above ground CO2 is beneficial for the photosynthesis of plants.

– Urea does not leave any harmful residues. Except the amo part can be washed into the water.

– This is a very soluble fertilizer, not harmful to plants.

2. Other Applications

– In addition to agricultural applications, Urea N is also used in waste treatment systems, reducing the odor of nitric oxide gas.

– Urea fertilizer is a source of protein nutrition for herbivores (cattle)

How to fertilize urea is reasonable?

– Urea is very easy to use because it is suitable for many different soils and plants. Very suitable when applied on acidic soil.

– To fertilize Urea for plants, you can mix it into the soil or sprinkle it on the top layer of soil. With a fairly high solubility, Urea can be dissolved in water to form a liquid form and then added to irrigation water or to spray plants, making it easy for plants to absorb.

– To spray directly on the leaves, dilute to a concentration of 1-1.5% and should be sprayed in the early morning or late afternoon so that the plants can absorb the best and avoid the loss of evaporation.

Urea fertilizer production process

Để sản xuất ra phân đạm Urea, người ta sử dụng phản ứng giữa khí Amoniac (NH3) và khí Cacbon dioxide (CO2) trong điều kiện nhiệt độ và áp suất nhất định. Khi Urea nóng chảy sẽ tạo hạt hình cầu bằng các thiết bị tạo hạt chuyên biệt hoặc làm cứng thành các miếng nhỏ khi rơi trong hệ thống tháp cao.

Pay special attention in the production process, when two molecules of asexual urea stick together to create a new molecule called Biurea. This is an extremely harmful ingredient for plants. With the rate of Biurea from 2.5% - 3.1% will be toxic to plants. Because of that danger, the production process is strictly controlled, the maximum level specified in Biurea must not exceed 1.2%.

Some notes when using and storing urea nitrogen fertilizer.

– Urea fertilizer is volatile and easily washed away, so people need to pay attention to use it properly to avoid waste.

Plants can be weak if too much nitrogen is applied.

– In case the amount of Biurea in the manure exceeds the specified level, it can be harmful to plants. To overcome, people need to mix Urea with porous soil for 2-3 days and then apply fertilizer, this will cause Biurea to hydrolyze and become ammonium carbonate.

– Before using Urea fertilizer in particular and other fertilizers in general, people should carefully read the instructions for use and indications of the manufacturer and ask for information with the manufacturer to be able to use it properly. rational and effective.

Methods of preservation

Store urea carefully in a polyethylene bag and avoid exposure to sunlight. Due to easy decomposition and volatilization when exposed to air and light. Keep in dry places.
