Stimulate the growth and reproduction of beneficial microorganisms in the soil. Improve the natural resistance of plants to pests and diseases. Now on the market, potassium fulvic acid and potassium humate are flying all over the sky. Even if there is compound fertilizer in the material, it is also interpreted as potassium fertilizer. Today, I am for you Uncover their mysteries.

Potassium humate, not pure potassium.

Potassium fulvic acid is a component of potassium fulvic acid. Humic acid is widely found in natural peat, lignite, weathered coal, etc. Fulvic acid can be extracted from humic acid fulvic acid and potassium oxide.

Using plant residues as raw materials, a coal-like potassium fulvic acid material was successfully produced through biological fermentation. Using biochemical technology to extract potassium fulvic acid from plants, and then use potassium oxide to produce potassium fulvic acid. The main content of potassium fulvic acid It is potassium humate (50 percent dry basis), total nitrogen (n) 3.0 percent, total phosphorus (p) 0.4 percent, and total potassium (k2o) 11.7 percent.

In other words, in 100kg potassium xanthate, pure nitrogen is 3 percent, pure phosphorus is 0.4 percent, pure potassium is 11.7 percent, and total nitrogen, phosphorus and potassium is 15.1 percent. If you add 20kg potassium fulvic acid to a bag of compound fertilizer, the maximum For 2-3 pure potassium, 7-8kg potassium humate is about 1kg potassium chloride.

Potassium humate is not pure potassium either.

The appearance of potassium humate is black granular or powdery solid, which is selected from lignite and extracted by Koh liquid reaction. The potassium humate market in China is very chaotic, and some manufacturers use potassium humate, which is what we call coal head and coal powder.

Research on compound fertilizer labels.

Some compound fertilizers on the market are marked with Comb, and many salespeople explain that this is the meaning of potash. Through our online searches and consulting professionals, we know that Com and potash are just soil conditioning materials.
