Chemical fertilizers, referred to as chemical fertilizers, are important agricultural production materials. In recent years, various incidents of falsely degrading fertilizer pits and farmers have occurred from time to time, causing great losses to rural economic development and farmers' interests. How can we avoid buying fake fertilizers? According to our many years of work experience, we provide a number of farmers with simple identification methods and precautions for the quality of chemical fertilizers for everyone to refer to when purchasing fertilizer: First, simple identification methods 1. Urea white, Small, uniform crystals, transparent, completely soluble in water. Place it on a red-hot piece of iron, not burning, and take a white smoke. When you take a piece of glass and touch white smoke, you can see a layer of white crystalline material on the glass. 2. Ammonium nitrate white granular crystals, uniform, slightly larger than urea particles, all soluble in water. Mix with alkaline substances such as lime and stir to smell ammonia. Placed on a red-hot piece of iron, it burns and makes a buzzing sound. The flame is orange and the smoke has ammonia smell. 3. Diammonium diammonium (diammonium) brown or light brown, translucent glossy, uniform particles, hard, almost all dissolved in water. Placed on red-hot pieces of iron, gradually melting, smoke and ammonia smell. 4. Potassium sulphate is white or slightly yellow-brown and crystal-like. All soluble in water. There was no change on the red iron. 6. Compound fertilizer compound fertilizer is the most chemical fertilizer product in the fertilizer market. It includes various special fertilizers. Its particle size and color differ depending on the raw materials used, but the qualified crystals should be uniform in particle size, dry and have a certain hardness, are not easily broken, and there are no or few powders in the bag. Second, note 1. It is necessary to purchase chemical fertilizers from the designated national designated units, that is, agricultural material companies at all levels, fertilizer manufacturers, and agricultural "three stations", and do not purchase them from individuals or other informal sales outlets. 2. When you purchase fertilizer, you must carefully read the chemical fertilizer inspection certificate and the logo on the packaging bag. It must have a production license number, effective nutrient content and the manufacturer's address. 3. When purchasing fertilizer, you must ask for an invoice in preparation for future quality problems. 4. Once chemical fertilizer quality problems arise, they must promptly file complaints with technical supervision departments and business administration departments at all levels. The above identification methods and precautions cannot completely avoid the purchase of fake deteriorating fertilizers, but everyone pays more attention to the purchase of fertilizers, which can greatly reduce losses. For some fertilizers that cannot be judged by themselves, they can be sent to the relevant quality inspection department for inspection.
