Potassium formate water-soluble fertilizer can effectively adjust the pH of the soil, greatly reduce the use of pesticides and fertilizers, thereby reducing agricultural non-point source pollution and ensuring the quality and safety of agricultural products and the safety of the ecological environment. However, many distributors or farms reported that the fertilizer market was extremely chaotic in the first half of this year. Potash fertilizer on the market was complicated and the price was chaotic, which had a relatively large impact on the market. Therefore, we must be alert to fertilizer fraud and understand potassium formate water-soluble fertilizer to avoid being "routine".

Potash fertilizer belongs to a certain acid salt of a strong base. The corresponding to nitrate is called potassium nitrate, the corresponding to sulfate is called potassium sulfate, the corresponding to hydrochloric acid (also called hydrochloric acid) is called potassium chloride, and the corresponding to carbonate is called carbonic acid. Potassium, corresponding to phosphate is called potassium phosphate (monopotassium phosphate, dipotassium phosphate, tripotassium phosphate, potassium polyphosphate, potassium polyphosphate, etc.), and organic acid root is called organic potassium (potassium formate, potassium acetate, lemon Potassium acid, etc.), and the corresponding silicate is called potassium silicate.

At present, inferior potash fertilizer is used as regular potassium formate water-soluble fertilizer on the market. However, potassium formate foliar fertilizer requires very high solubility. Potassium formate is used in water-soluble high-potassium water-soluble fertilizer. The solubility is extremely high. It can dissolve 337g in 100g water at 20°C and 313g in 100g water at 10°C. The pH of the saturated solution of potassium formate water-soluble fertilizer is about 9, which can improve soil acidification and other problems to a certain extent.

There are many ways to make and sell fake fertilizers to deceive farmers. The most prominent one is "stealing content." Potassium formate foliar fertilizer is dissolved from solid to liquid, and when it is diluted from liquid, use deionized water or distilled water as much as possible. The quality standard of potassium formate solid content is ≥97%, and potassium formate liquid is ≥74%.

The logo is the identity card of the fertilizer and the instruction manual. Some chemical fertilizer packaging bags are marked with "total active ingredients" and "element content", but this marking is not standardized. Excessive application of potassium fertilizer can easily cause soil salt to accumulate. One is that most potash fertilizers are water-soluble salts. The other is that when the crop absorbs potassium ions, the water-soluble side components in the potash fertilizer, such as sulfate ions and chloride ions, combine with calcium ions or sodium ions in the soil to form sodium sulfate and chloride. Calcium is dissolved in the soil, causing the salt to rise. Excessive use of potassium fertilizers will also cause soil environmental pollution and water pollution, and weaken crop production capacity.

Potassium formate foliar fertilizer has a very high solubility (ten times or even dozens of times that of other potassium fertilizers), and a very low content of harmful chloride ions (one thousandth of that of other potassium fertilizers).

It is difficult to judge whether the fertilizer is good or bad, because there are too many factors involved, the effect of the fertilizer is often exaggerated, and it is also claimed that the fertilizer with this content does not need to be sprayed later. So we must first understand the potassium formate water-soluble fertilizer to avoid being "routine".
