Period of using potassium humate from mineral sources
It is advisable to use it no less than 3-4 times a year. Several periods of use are recommended:
Before flowering
A large amount of nutrients are consumed during the flowering and fruiting period. Insufficient nutrients are prone to flower and bud drop. It is generally not recommended to water more during the flowering period, which is prone to poor fruit setting. We need to supplement nutrients before flowering to ensure that the crop spends the entire flowering period stably. We usually recommend supplementing high-phosphorus water-soluble fertilizer and potassium humate from mineral sources before flowering.
Young fruit expansion period
The reason is the same as above. The young fruit expansion period is a period of rapid cell division, which requires a large amount of nutrients. While using balanced macronutrients, we must also use potassium humate from mineral sources.
After bagging fruit trees, before continuous high temperatures in summer
During this period, potassium humate from mineral sources is used. One is to allow potassium humate to continuously integrate and supply nutrients to crops, and continue to expand in the bag. There is another important reason: anti-early! Potassium humate from mineral sources occurs in the soil and becomes a binder. It combines with soil makeup to form a humate-like soil complex and becomes a water-stable granular structure.

Thus, it greatly improves the soil’s aeration and anaerobicity, oxidation and reduction, water permeability and water retention, fertilizer supply and fertilizer retention, and improves the soil’s water, fertilizer, air, and heat conditions: greatly improves the effectiveness of soil nutrients, forming a small “storage” and a small fertilizer storage to cope with the continuous high temperature and dry summer
Before coloring
When the crop enters the color change period, the leaves, branches, and roots are already exhausted: aging, yellowing, and degradation are serious, especially the root absorption capacity decreases. At this time, the fruit coloring requires a lot of nutrients, not only to supply the fruit, but also to supply the flower buds. It is recommended to use high-potassium macronutrient water-soluble fertilizers, and use mineral potassium fulvic acid, which has both fast and lasting effects, so that the fertilizer will not be lost in the later period, and avoid the phenomenon of fertilizer loss such as green soft grains.
The use of fertilizers is very critical. For example, strawberries, grapes, etc., which have a long color change period, are prone to lack of fertilizer in the late stage of maturity. The main reason is that the nutrient accumulation of the early technology is insufficient, and the fertilizer effect of flushing fertilization is short. In addition, it is not suitable to water frequently in the later stage. Moreover, some places cannot be watered, resulting in a broken nutrient supply chain and lack of fertilizer. This time, the use of mineral potassium humate should be increased to continuously supply sufficient nutrients for fruit coloring, so that the color can be good, the sweetness is high, and the taste is good.
