Fulvic Acid

Fulvic acid stimulates crops physiological metabolism

Many farmers now know that humic acid is highly effective and environmentally friendly, but many people do not know the principle.Expert research shows that fulvic acid is the smallest and most active component of humic acid and the essence of humic acid.

In the practical application of agricultural production, the stability of fulvic acid is the best. Fulvic acid is the best core component of soil humus. It is a small molecular weight, fully water-soluble organic aromatic substance which is decomposed and decomposed by organic matter. It is the best humic acid component in soil and the core material for the formation of soil aggregate structure. .

The fulvic acid contains functional groups such as carboxyl group and phenolic hydroxyl group, which has strong complexation, chelation and surface adsorption ability, can reduce the loss of ammonium nitrogen, increase the moving distance of phosphorus in the soil, and inhibit the fixation of water-soluble phosphorus in the soil.

Ineffective phosphorus is converted into effective phosphorus, which promotes the absorption of phosphorus by roots; fulvic acid can absorb and store potassium ions, and the effective potassium content is especially effective for potassium fertilizer. Tests have shown that fulvic acid can increase the utilization rate of nitrogen, phosphorus and potassium nutrients in fertilizers by more than 20%.

The effect of fulvic acid combined with nitrogen on plant growth and development is very obvious. When nitrogen and fulvic acid are sufficient, plants can synthesize more protein, promote cell division and growth, so the plant leaf area grows faster, and more leaf area can be used for photosynthesis. It has obvious effects on promoting plant growth and health. Often, after application, the leaf color turns green quickly and the amount of growth increases.

The acidic functional group of fulvic acid can absorb and store potassium ions, and reduce the amount of potassium lost with water in sandy soil and leached soil. The fulvic acid prevents the fixation of potassium in sticky soils and increases the amount of exchangeable potassium. The fulvic acid has a dissolution effect on the potassium-containing minerals, slowly increasing the release of potassium and increasing the content of available potassium in the soil. Fulvic acid can also use its biological activity to stimulate and regulate the physiological metabolism of crops, increasing the potassium uptake by more than 30%.

The combination of fulvic acid and potassium promotes photosynthesis, can significantly increase the absorption and utilization of nitrogen by plants, and is quickly converted into protein, and can also promote plant economic water.

In addition to a large number of elements such as nitrogen, phosphorus and potassium, crop growth and development also requires trace elements such as iron, boron, manganese, zinc, molybdenum and copper. They are components of various enzymes in the crops and promote the normal growth and development of crops. Increasing disease resistance, increasing yield and improving quality all have important implications. Most of the trace elements in the soil are in an ineffective state that plants are difficult to absorb, and the application of trace element fertilizers to the soil is also easily fixed by the soil.

According to the research, decoctantic acid can react with trace elements such as iron and zinc to form a sulphate trace element chelate compound with good solubility and easy to be absorbed by plants, such as fulvic acid-Zn and fulvic acid-Mn. , fulvic acid-Fe, etc., is conducive to the absorption of roots or leaves, and can promote the trace elements from the roots to the upper part of the ground.

The experiment showed that the amount of iron fulvic acid entering the roots from the roots was 32% more than that of ferrous sulfate, and the number of movements in the leaves was twice that of ferrous sulfate, which increased the chlorophyll content by 15 to 45%, effectively solving the problem caused by iron deficiency. Yellowing of the leaves.
