The humic acid products currently on the market are rather chaotic and there is no uniform standard. NY/T1106-2010 "Humic Acid-Containing Water Soluble Fertilizer" is an industry standard for humic acid fertilizers issued by the Ministry of Agriculture of my country, which is currently being adopted. Others are corporate standards. So far, no other standards and industry labels related to humic acid fertilizers have been issued. Therefore, the current implementation standard is NY/T1106-2010 "Humic acid-containing water-soluble fertilizer", which is a real humic acid-containing fertilizer.

When humic acid is added to compound fertilizer or blended fertilizer, only the content of humic acid can be marked on the package components, but the name on the fertilizer package cannot be changed, that is, the package must be marked as compound compound Fertilizers or mixed fertilizers, and cannot be labeled as compound fertilizers containing humic acid. At the same time, the content of nitrogen, phosphorus and potassium in chemical fertilizers must also meet the requirements of compound fertilizers or blended fertilizers.

(2) See if humic acid is labeled.

The content of humic acid should be clearly marked on the package, such as: humic acid content ≥20%. If only the words humic acid are marked, but not how much it contains, it is not very formal. If it contains 0.01%, it is also called water content.

(3) Check the product manual.

The use of humic acid fertilizers varies in different crops and at different periods, so the description must be written in a comprehensive and detailed manner, and the difference in the amount used in the growing period of the crop must be distinguished. If the writing is rough, and there is no professional technician to guide the use, it is recommended not to buy.

When buying, keep the receipts, packaging and samples, and safeguard your rights in time if there are any problems.
