Precautions when buying fertilizer products

Precautions when buying fertilizer products：

(1) Packaging materials: the outer bag is a plastic woven bag, the inner bag is a film bag, and a two-in-one film bag can also be used. Ammonium carbonate does not need to be packed in a composite bag.Any packaging materials that do not meet the above requirements may be counterfeit and shoddy products.

(2) The logo on the packaging bag: The packaging bag should be marked with the fertilizer name, nutrient content, grade, net weight, implementation standard number, production plant name, site, quality certificate, and some should also have fertilizer registration certificate, production license number, etc.If the above logo is absent or incomplete, it may be a fake or shoddy product.

(3) Nutrient content: Nutrient content mainly refers to the content of nitrogen, phosphorus, and potassium. If medium elements (sulfur, calcium, magnesium, sodium) or trace elements (copper, zinc, iron, manganese, molybdenum, and boron) are added to the product, the content and total content of each medium element, and the content and total content of each trace element should be separately indicated.Nitrogen + phosphorus + potassium + sulfur + calcium + magnesium + sodium + copper + Zinc + iron + Manganese + molybdenum + boron ≥58%, 85% and other standard methods cannot appear.

(4) When there are additives in the product, it must be mixed evenly with the raw materials and cannot be placed in a small package in a packaging bag.

(5) Care should be taken to keep the fertilizer purchase voucher. The fertilizer purchase voucher is an invoice or receipt. The name, quantity, grade or content, price and other contents of the purchased fertilizer should be indicated in the ticket.If the distribution unit refuses to issue a fertilizer purchase certificate, farmers can report to the agricultural administrative law enforcement department or the industrial and commercial administration department.

(6) If you purchase more than half a ton of fertilizer, it is best to keep a bag unopened as a sample, and wait for the current season's crops to be harvested without problems before handling it by yourself.
