Tests show that fulvic acid, an active ingredient in Shilajit extract, can improve fertilizer utilization by more than 20%. This article will specifically introduce the reasons for fulvic acid to enhance fertilizer utilization.
1. Synergistic effect on the nitrogen fertilizer
The active groups of fulvic acid are generally electron donors, which can quickly form coordination compounds with many electron acceptors, called complexes or chelates. For example, fulvic acid-urea can reduce the loss of ammonium nitrogen and improve the utilization rate of nitrogen fertilizer.
The combination of fulvic acid and nitrogen has a pronounced effect on plant growth and development. They cause plants to synthesize more protein, promoting cell division and growth. Therefore, the plant's leaf area grows rapidly, and more leaf area can be used for photosynthesis. Often after application, leaf color quickly turns green and growth increases.
2. Synergistic effect on phosphate fertilizer
Degraded nitrofulvic acid increases the distance phosphorus travels in the soil. It converts ineffective phosphorus into adequate phosphorus and promotes phosphorus absorption by the root system. Use fulvic acid to protect water-soluble phosphorus fertilizers or phosphorus-based compound fertilizers, promote phosphorus absorption, and improve fertilizer utilization. Fertilizer efficiency tests show that adding 10-20% fulvic acid to common calcium, heavy calcium, or ammonium phosphate can increase fertilizer efficiency by 10-20% and increase phosphorus absorption by 28-39%. After adding fulvic acid, the utilization rate of phosphorus fertilizer was raised by a quarter.
Fulvic acid and phosphorus fertilizers are involved in photosynthesis, respiration, energy storage and transfer, cell division, cell enlargement, and other plants' processes.
3. Synergistic effect on potassium fertilizer
The acidic functional groups of fulvic acid reduce the amount of potassium lost with water in sandy and other soils. Fulvic acid prevents potassium fixation in cohesive soils and increases the amount of exchangeable potassium. Fulvic acid has a dissolution effect on potassium-containing minerals, slowly increases the release of potassium, and increases the content of available potassium in the soil. It can also use its biological activity to increase potassium absorption by more than 30%.
In addition to promoting photosynthesis, it can significantly improve the absorption and utilization of nitrogen by plants when used together with potassium.
