Not long ago, everyone said that there is no need to blindly follow the trend to expand the efficacy of potassium fulvic acid. "One kg of fulvic acid is worth 8 tons of organic fertilizer" is unreliable. Regarding potassium fulvic acid, many people also use it as a kind of " "Almighty fertilizer" is used, and even some farmers apply potassium fulvic acid for a whole season, but some farmers regret it in the second year after application.

1. What is the relationship between potassium humate and humic acid?

Humic acid contains fulvic acid, brown humic acid, black humic acid, etc. Fulvic acid is only one type of humic acid, and fulvic acid products on the market exist in the form of acid salts, so it has "potassium fulvic acid" , Potassium fulvate sold on the market is the product of potassium fulvate that has been purified, produced and processed by the manufacturer.

Potassium fulvate sold on the market includes biochemical potassium fulvic acid and mineral potassium fulvic acid. Biochemical potassium fulvic acid is the leftover material for the production of soft white sugar and chicken essence, among which "sugar cane molasses" is the key raw material. , and the mineral potassium fulvic acid comes from animal and plant residues of 100 million years, obtained from coal slime produced in 100 million years, with colorful functional group isomers such as methyl, phenolic hydroxyl, methoxy, etc. There are rich and colorful essential element nutrients, and mineral fulvic acid is much higher than biochemical potassium fulvic acid in terms of nutrition and soil organic matter.

In terms of practical effect, if one kilogram of mineral potassium fulvic acid is applied per mu of land, then 10 kilograms of biochemical potassium fulvic acid is required. Therefore, mineral potassium fulvic acid is a first-class humic acid commodity. Return to the beginning of the article The problem is that if potassium fulvic acid is used, even if it is mineral potassium fulvic acid, other chemical fertilizers cannot be used, right?

2. If potassium humate is used, there is no need for other fertilizers?

Some farmers believe in the specific instructions of some "agricultural technicians" and use potassium fulvic acid for the whole season, but they find that the green plants that use potassium fulvic acid have really good results in the first season, no matter in terms of quality. And the throughput above is so good, in fact it's an illusion.

The demand for potassium humate is not large, and the total nutrient output is still insufficient, but potassium humate can stimulate the nutrient chemical substances of essential elements that are fixed in the soil layer. This essential element nutrition is replaced by potassium humate. After being stimulated, it can be digested and absorbed by green plants again. In addition, the rhizomes of crops can also be improved, and the digestion and absorption effect is stronger, which can indeed show a good actual effect of high yield and quality.

If only potassium humate is used in the second year, there will be less nutrients such as light fertilizers remaining in the soil layer, and crops will mainly show symptoms of defertilization!

The application of potassium fulvic acid can improve the efficiency of chemical fertilizer digestion and absorption, and reduce the application of organic fertilizer by 15-20%, but potassium fulvic acid is not an all-round fertilizer, and it is not recommended to provide all-round nutrition for green plants.

3. How do farmers use potassium fulvic acid to have a very good effect?

It is recommended that everyone use general water-soluble fertilizers or compound fertilizers together with potassium fulvic acid, which can not only reduce the application of organic fertilizers, but also further improve the fertility of water-soluble fertilizers and compound fertilizers, and achieve greater potassium fulvic acid. Use value, it is proposed to use 5-10kg of water-soluble fertilizers with large amounts of elements and 1 catties of high-quality mineral potassium fulvic acid per acre of land. The actual effect is more pronounced in the case of setbacks.

Farmers can choose a reliable manufacturer of mineral potassium fulvic acid. Pure potassium fulvic acid has good water solubility, strong resistance to water hardness, and can be sprayed or flushed. It is suitable for promoting land improvement, improving rhizome growth and development, improving Disease resistance and stress resistance of green plants can improve crop quality and production.
