Promoting Effect of Fulvic Acid on Medium and Trace Element Fertilizers

Fulvic acid is a gray-black powdery substance soluble in water. It is a kind of biostimulant, which can promote plant growth, play an important role in drought resistance, improve plant stress resistance, increase production and improve quality.

Fulvic acid can promote the absorption of micro-fertilizers and effectively solve the symptoms of crop nutrient deficiency:

The trace elements in the fulvic acid chelation form a fulvic acid chelate with strong mobility and easy absorption by crops, which is delivered to the deficient parts of the crops, effectively solving the deficiencies.

In addition to the large amount of elements such as nitrogen, phosphorus, and potassium, the growth and development of crops also need trace elements such as iron, boron, manganese, zinc, molybdenum, and copper. Improving disease resistance, increasing yield and improving quality all have important effects.

Most of the trace elements in the soil are in an ineffective state that is difficult for plants to absorb, and the application of trace element fertilizers to the soil can also be easily fixed by the soil.

It has been found through research that fulvic acid can undergo chelation reactions with trace elements such as iron and zinc to form fulvic acid trace element chelates with good solubility and easy absorption by plants, such as fulvic acid-Zn and fulvic acid-Mn , fulvic acid-Fe, etc., which are beneficial to the absorption of roots or leaves, and can promote the transfer of trace elements from roots to shoots. The tracer test shows that the amount of ferric fulvic acid entering the plant from the root is 32% more than that of ferrous sulfate, and the amount of moving in the leaves is twice that of ferrous sulfate, which increases the chlorophyll content by 15-45%, effectively solving the problem caused by the deficiency. Iron causes leaf yellowing.

The effect of using fulvic acid in combination with individual medium and trace elements:

1. Rice is a silicon-loving crop. Rice uses fulvic acid silicon fertilizer to increase grain weight, mature early, and improve disease resistance. It can enhance the resistance of crops to pests and diseases and reduce the damage of pests and diseases; it can improve the lodging resistance of crops, enhance the ventilation of crops, and improve the stress resistance of crops; it can reduce the stability of phosphorus in the soil; it can improve the quality of agricultural products, and Conducive to storage and transportation.

2. Fulvic acid combined with calcium fertilizer can reduce fruit absorption, increase fruit firmness, make fruit storable, reduce rot, and increase Vc content.

3. Fulvic acid combined with magnesium fertilizer can promote photosynthesis of plants, promote protein synthesis, increase crop yield and improve the quality of agricultural products.

4. Fulvic acid combined with sulfur can increase the protein content, improve the quality of cereal crops, increase the content of vitamin A and the oil content of oil crops, and at the same time improve the quality of fruits, vegetables, sugar beets and other varieties, and can enhance the cold protection and protection of crops. drought resistance.

5. Fulvic acid combined with zinc is absorbed by plants in the form of Zn2+. In nitrogen metabolism, it can well change the ratio of organic nitrogen and inorganic nitrogen in plants, greatly improve the ability to resist drought and low temperature, and promote the healthy growth of branches and leaves. ; Participate in chlorophyll production, prevent the degradation of chlorophyll and form carbohydrates.
