What should I pay attention to when buying fertilizer products

1. Look at the packaging materials. The outer bag is a plastic woven bag and the inner bag is a film bag. You can also use a two-in-one film bag. Ammonium carbonate does not need to be packed in a composite bag.
2. Look at the logo. 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.Fertilizers containing multiple elements should be marked separately with the content and total content of each element.
3. Look at the additives. If the fertilizer contains other additives, it must be mixed with the fertilizer, not packed separately.

 How to buy fertilizer correctly?
1. Keep an eye on the packaging, see the nutrient content of nitrogen, phosphorus and potassium clearly, and calculate for yourself whether the content is correct.
2. Try to buy from big manufacturers. Don't just listen to those small vendors and those who sell fertilizers. It's easy to buy fake fertilizers.
3. There are many standards for fertilizers. It is best not to buy corporate standards. Look at the signs clearly, such as national standards (GB), industry standards (NY or HG), landmarks (DB/), and corporate standards (Q/).
