The effect of mineral potassium humate is very good, but many people feel that it is not very good after using it, because they have not grasped the operation method. The following is a summary of some of the more common misconceptions.

1. Mineral potassium humate is not used as much as possible at one time, but should be eaten in small quantities. Using 5KG at a time is not as good as using 1KG at a time, and using it continuously for 4 times.

2. It is not necessary to apply light flushing, flushing and spraying fertilizer closely, and the synergistic effect is more significant.

3. Not every crop mainly shows the visible effect of mineral potassium humate. When applying, it is necessary to understand the initiative of the crop beforehand:

①The effect of mineral potassium humate is more significant on root crops, so the marketing and promotion test should grasp the roti, potatoes, sweet potatoes, etc.

② Melon vegetables with very spacious leaves and their wheat, rice, etc.

③The crops with insignificant effects include rapeseed, castor and other fuel crops. Although there are specific effects, such as the growth and development rate of rhizomes, root-shoot ratio, etc., the data information can only be tested by effective methods, and it is difficult for the human eye to identify.

4. The soil layer itself contains a lot of humic substances. When the standard is very good, the effect of using mineral potassium humate is not significant. Therefore, mineral potassium humate can be used for "icing on the cake", not "the finishing touch". For alkalization and agglomerated soil, use 1KG, and the effect is better than using 5KG for normal soil layer.

What are the tips for applying mineral potassium humate?

1. The mineral source potassium humate is used with fertilizers and inorganic water-soluble fertilizers, which can reduce the basic usage of fertilizers and inorganic water-soluble fertilizers by 10% to 20%.

2. Mineral source potassium humate will cause deposition when it encounters chlorite in the water. In order to avoid blocking the sprinkler irrigation holes, when drip irrigation of humic acid fertilizers, it is necessary to avoid the length of sprinkler irrigation, ensure a small amount of meals, and at the same time ensure sufficient dilution. .

3. Although mineral potassium humate can be applied in the whole growth period of crops, due to the consideration of economic development, it is recommended to irrigate twice in each of the 4 critical periods of crop planting, before flowering, puffing, and bag removal. In the bag period, the effect of fertilizer spraying mineral source potassium fulvic acid or mineral source fulvic acid chelated zinc will be better.

5. According to the requirements of the Ministry of Agriculture of the People's Republic of China for water-soluble fertilizers containing humic acid, the raw material of humic acid must be mineral source humic acid. There are 2 ways to identify mineral source or biochemical humic acid:

①Smell: Mineral source humic acid is tasteless, and biochemical humic acid has different fragrances, sugar cane molasses, etc. depending on the source;

②Color vision: Mineral source humic acid is mostly gray-black, and biochemical humic acid is mostly zongzi or yellow-brown.
