In 2016, the sales of agricultural materials entered the peak season to purchase qualified fertilizers.

In 2016, agricultural sales entered the peak season to purchase qualified chemical fertilizers. Keep valid proof of purchase. In March, it was the key season for spring planting, and agricultural products began to enter the sales season. In conjunction with previous complaints and practical experience, Chun'an City Management Bureau reminded farmers to pay attention to the following four aspects when purchasing agricultural materials to reduce losses.

First, look at the packaging. The packaging of chemical fertilizers is fiber woven packaging, and high-concentration compound fertilizer or unit fertilizer should be lined with polyethylene film bags to prevent water absorption and moisture. The package should have nutrient content, moisture content, production license number, product certification, quality implementation standards, manufacturer and site, and telephone number. Some cash crops (if trees, tea, tobacco, etc.) cannot be applied with chlorine-containing compound fertilizers. Pay special attention to the instructions on the package when purchasing.

Second, look at the color and shape. For example, ammonium bicarbonate is white fine-grained crystal, urea is colorless needle-like or prismatic crystal, the compound fertilizer has uniform grain shape, uniform color, no powder or a little powder, and the particles are uniform, loose and dry, and not sticky. Not agglomerated. If the agglomeration indicates that the water has been absorbed by moisture, the moisture content has exceeded the standard; the superphosphate is grayish white or granular compound. Generally, the lighter the color, the no powder is agglomerated, the higher the nutrient content, the deeper the color and the higher the humidity, the higher the nutrient content. low.

Third, smell the smell. Different fertilizers have different odors. For example, ammonium bicarbonate has an ammonia smell; urea is an odorless granular material, and should not have an ammonia smell; the compound fertilizer should have a slight acidity, and it should be observed after exhalation on the hand, and should be absorbed and deliquescent; superphosphate should be Slightly sour, should not have a pungent smell.

Fourth, leave the voucher. When purchasing, you must obtain other legal and valid vouchers such as invoices, quality credit cards, etc., and keep the outer packaging bags of chemical fertilizers when using them. If there are any problems, you should promptly complain to the local industry and commerce and quality supervision departments. Jiang Guobiao
