With the arrival of the spring farming season, agricultural products have gradually begun to enter the peak season for sales. Recently, the author contacted law enforcement officials, who combined with previous complaints and practical experience to tell farmers that they should pay more attention to the following four aspects when purchasing agricultural products to avoid being deceived.
First, look at the packaging
Fertilizer packaging is fiber woven packaging. High-concentration compound fertilizers or unit fertilizers should be lined with polyethylene film bags to prevent water absorption and moisture. The packaging bag must have the nutrient content, moisture content, production license number, product certification, quality execution standard, manufacturer and site, and contact phone number. Some cash crops (such as trees, tea leaves, tobacco leaves, etc.) cannot be applied with chlorine-containing compound fertilizers. Pay special attention to the instructions on the package when purchasing.
Look at colors and shapes
For example, ammonium bicarbonate is white fine-grained crystals, urea is colorless needle-like or prismatic crystals, compound fertilizers are uniform in shape and color, no powdery or a little powdery, the particles are uniform, loose and dry, and not sticky. Does not cake. Such as agglomeration indicates that it has absorbed water and moisture, and the moisture content has exceeded the standard. Calcium superphosphate is off-white or granular compounds. Generally, the lighter the color, the powder is non-caking. low.
Third, smell
Different fertilizers have different smells. For example, ammonium bicarbonate has an ammonia smell; urea is an odorless granular substance, and it should not have an ammonia smell; compound fertilizers should have a slightly sour taste. Slightly sour, there should be no pungent stench.
Fourth, leave the voucher
Obtain invoices, quality credit cards and other legal and valid vouchers when purchasing, and keep the outer packaging bags of fertilizers when using them. If there are any problems, complain to the local industry and commerce and quality supervision department in time.
