Potassium humate in minerals works very well, but many people do not feel good after using it because they have not mastered the method of use. The following are some common misunderstandings.

1. The mineral potassium humate is not used as much as possible at one time, but the lesser it is used multiple times. It is better to use 5kg each time instead of 1kg each time, and use it 4 times in a row.

2. Do not apply light flushing, the combination of flushing and spraying, the synergistic effect is more obvious.

3. Not every crop has a visible effect on mineral potassium humate. In the process of use, the response of the crop should be known in advance:

①Mineral potassium humate has the greatest impact on root crops, so radishes, potatoes, sweet potatoes, etc. should be used in the promotion experiment.

② Melons with wider leaves, as well as wheat, rice, etc.

③ The crops with less obvious impact include oilseed crops such as rape and castor, and the actual impact is relatively large, such as root development speed, root-shoot ratio, etc., but the data can only be detected by scientific methods, and it is difficult to identify with the naked eye.

4. The soil itself contains a lot of humus. Under good conditions, the effect of applying mineral potassium humate is not obvious. Therefore, mineral potassium humate can be used to "send charcoal in the snow", not "icing on the cake". Use 1kg of saline alkali , acidified, compacted soil, the effect is better than using 5kg ordinary soil.

What are the tips for applying the mineral potassium humate?

1. The use of mineral potassium humate together with chemical fertilizers and inorganic water-soluble fertilizers can reduce the conventional dosage by 10% to 20%.

2. The mineral potassium humate will precipitate when it meets the calcium and magnesium ions in the water. In order to prevent the drip irrigation holes from being blocked, when drip irrigation of potassium humate, the number of drip irrigation should be minimized, and a small amount of drips should be achieved, while ensuring sufficient dilution.

3. Although mineral potassium humate can be used in the whole growth period of crops, due to economic reasons, it is recommended to apply it twice in each of the four key periods of crop transplanting, flowering period, expansion period and color change period. Combined with spraying mineral-source potassium fulvic acid or mineral-source fulvic acid chelated zinc, the effect is better.

4. According to the Ministry of Agriculture's standard for water-soluble fertilizer containing humic acid, the raw material of humic acid must be mineral humic acid. There are 2 mineral sources for identifying biochemical humic acid:

① Odor: Mineral-derived humic acid has no odor, and biochemical humic acid will have different aromas and molasses flavors depending on the source;

②Color discrimination: The humic acid derived from minerals is mostly black, and the biochemical humic acid is mostly brown or brownish yellow.
