What is the effect of potassium fulvic acid from mineral sources
1. Mineral yellow humic acid potassium: Mineral yellow humic acid potassium usually contains more than 50% yellow humic acid, 12% potassium oxide, and a pH value of 9-11. In practical applications, the technical indicators of various manufacturers vary, and the product belongs to small molecule organic matter, which can be directly absorbed and utilized by crops, with fast and long-lasting effects.
2. Decomposition of salt accumulation and improvement of root microenvironment: Mineral potassium fulvic acid has strong adsorption and ion exchange capacity, which is 10-20 times greater than that of general soil. It can exchange and adsorb salt ions in the soil, neutralize and buffer the harm of salt and alkali, and flocculate with soil particle structure to become a stable, water, fertilizer, and breathable small fertilizer reservoir.
3. Reuse of nutrients that chelate soil solidification: Mineral source potassium fulvic acid chelates trace elements such as calcium, magnesium, zinc, and molybdenum in the soil, generating high solubility humic acid calcium, zinc, and other nutrients that are easily absorbed by crops. It can also chelate with soil solidified phosphorus and solidified potassium to dissolve phosphorus and potassium, which plays an indispensable role in improving disease resistance, stress resistance, yield, and quality.
In addition, potassium fulvic acid from mineral sources is involved in the synthesis of various enzymes, increasing drought and cold resistance, promoting root growth, and promoting soil microbial activity.
How to use potassium fulvic acid from mineral sources
We commonly have two types of finished products: one is a refined and high-quality product, usually packaged in 1 kilogram, with a high price, good water solubility, and anti flocculation ability. It can be mixed with most fertilizers and is suitable for drip irrigation and flushing application. WeChat search for attention in the vegetable farming circle. Another type is ordinary mineral potassium humate, which is mostly in large pieces and has a lower price. It is usually packaged in 5-10 kilograms and cannot be dissolved without water. It takes 500 to 600 kilograms of water to dissolve a bag. It is recommended to ditch and sprinkle before watering.
It is advisable to use it no less than 3-4 times a year, and several recommended usage periods are:
1. Before flowering
During the flowering and fruiting period, a large amount of nutrients need to be consumed. Insufficient nutrients can easily cause flower and bud loss. However, it is generally not recommended to water more during the flowering period, which can lead to poor fruit setting. Therefore, we need to supplement nutrients before flowering to ensure that the crop can safely pass through the entire flowering period. Usually, we recommend supplementing high phosphorus water-soluble fertilizer and mineral potassium fulvic acid before flowering.
2. Young fruit expansion stage
The principle is the same as above. The swelling stage of young fruits is a period of rapid cell division, requiring a large amount of nutrients. While using balanced large amounts of elements, we also need to cooperate with mineral source potassium fulvic acid.
3. After bagging fruit trees, before continuous high temperatures in summer
During this period, potassium fulvic acid from mineral sources is used. One reason is to continuously chelate and supply nutrients to crops, and continue to expand the bag. Another important reason is drought resistance! Potassium humate, a mineral source, undergoes flocculation in the soil and becomes a cementitious agent. It combines with soil particles to form humate like soil complexes, forming a water stable granular structure, greatly improving the soil's breathability and aeration, oxidation and reduction, water permeability and retention, fertilizer supply and retention, and improving the soil's water, fertilizer, air, and heat conditions; Greatly improve the effectiveness of soil nutrients, forming a small reservoir and fertilizer bank to cope with continuous high temperature and drought in summer.
4. Before coloring
When crops enter the color transition period, their leaves, branches, and roots are already exhausted: aging, yellowing, and severe degradation. Especially when the absorption capacity of the root system decreases, and the fruit coloring requires a large amount of nutrients, not only to supply the fruit, but also to supply the flower buds. It is recommended to use high potassium water-soluble fertilizer with a large amount of elements, combined with the use of mineral source potassium fulvic acid, which has a fast and long-lasting effect, ensuring that the fertilizer is not removed in the later stage and avoiding the phenomenon of returning green and soft grains.
This use of fertilizer is crucial, for example, for citrus and grapes with a long color transition period, which are prone to fertilizer loss in the later stage of ripening. The main reason is that the nutrient accumulation in the branches is insufficient in the early stage, and the fertilizer effect of flushing fertilization is short, and it is not suitable for frequent watering in the later stage. Moreover, some places cannot be watered, leading to nutrient supply chain interruption and fertilizer loss. This use of mineral potassium fulvic acid should be increased to continuously and adequately supply the nutrients required for fruit coloring, Only with good color, high sweetness, and good taste.
