Urea ammonium nitrate solution is a commonly used nitrogen fertilizer solution, which contains two nitrogen sources: urea and ammonium nitrate. Urea is a nitrogen-containing compound that can provide the nitrogen element needed by plants, promoting their growth and development. Ammonium nitrate is also a nitrogen-containing compound with a high nitrogen content, which can be quickly absorbed and utilized by plants.
Nature:
1. Appearance: Usually a colorless or slightly yellow transparent liquid.
2. Solubility: Easily soluble in water, forming an alkaline solution.
3. Nitrogen content: It contains two nitrogen sources, urea and ammonium nitrate, and has a high nitrogen content, which can effectively provide the nitrogen element required by plants.
Method:
The preparation of urea ammonium nitrate solution generally involves mixing urea and ammonium nitrate in a certain proportion and adding an appropriate amount of water for dissolution. During the preparation process, attention should be paid to controlling the concentration of the solution to avoid plant burns caused by excessive concentration. The prepared solution needs to be stored and diluted appropriately as needed during use.
Security information:
1. During use, it is important to avoid contact with skin and eyes. If in contact with skin, rinse immediately with water.
2. Avoid direct inhalation of gas and use in well ventilated areas.
3. Keep away from fire and heat sources during storage and use to prevent fire or explosion accidents.
4. Dilute and dilute according to the product instructions during use to avoid plant burns caused by excessive concentration.
