Potassium fulvate sold in the market includes biochemical potassium fulvic acid and mineral potassium fulvic acid. These two substances are the raw materials for making sucrose and monosodium glutamate. Among them, "molasses" is an important raw material, while mineral potassium fulvic acid comes from several sources. It is extracted from plant residues for hundreds of millions of years and extracted from lignite formed over hundreds of millions of years. It is rich in hydroxyl, phenolic, methoxyl and other functional groups, and also rich in mineral nutrients, whether it is the nutrition of mineral potassium fulvic acid. The ingredients are still organic, and they are much higher than the biochemical potassium humate.

Although the amount of potassium humate is not large and the total amount of nutrients is insufficient, it can activate the fixed mineral nutrients in the soil. Well, it can indeed reflect the good effect of increasing production and improving quality.

For example, if only potassium humate is used every year, the residual nitrogen, phosphorus, potassium and other nutrients in the soil will be reduced, and the crops will be defertilized!

However, potassium humate is not a universal fertilizer, and it is not recommended to use it alone, because it can improve the absorption efficiency, reduce the amount of chemical fertilizers by 15-20 percent, and is only used for the overall nutrition of the plant.

The use of water-soluble potassium fulvic acid should pay attention to the following matters:

Water-soluble potassium fulvic acid is one of the quick-acting fertilizers, generally cannot replace other conventional fertilizers, and can only be used as top dressing. In order to reduce costs and make full use of the advantages of various fertilizers, water-soluble potassium fulvic acid potassium water-soluble fertilizers should be combined with Mixed with conventional fertilizers.

2. When using it, users should pay attention to the high nutrient content of water-soluble fertilizer, so if it is directly treated with granules, it is easy to cause burning of seedling roots and weak seedlings. Therefore, it needs to be diluted twice before it can be used. When farmers use it. The amount of fertilization should be calculated correctly.

The most commonly used methods of using potassium fulvic acid water-soluble fertilizers are sprinkler irrigation, drip irrigation, irrigation, etc. In order to avoid waste and uneven use of chemical fertilizers, flood irrigation or flowing water irrigation should be avoided.

Compared with compound fertilizers, this type of water-soluble fertilizer has the characteristics of quick-acting, not easy to be stored in the soil for a long time, and long-lasting effect. Therefore, in the use of water-soluble potassium fulvic acid fertilizer, it should be used as little as possible.
