How does fulvic acid improve the utilization of nitrogen, phosphorus and potassium in fertilizers?

Fulvic acid is the best core component of soil humus. It is a small molecular weight and fully water-soluble organic aromatic substance produced by decomposition and decomposition of organic matter. It is the best humic acid component in the soil and the core substance that forms the soil aggregate structure. 


Fulvic acid contains functional groups such as carboxyl and phenolic hydroxyl groups. It has strong complexing, chelating and surface adsorption capabilities, which can reduce the loss of ammonium nitrogen; increase the distance of phosphorus in the soil, inhibit the fixation of water-soluble phosphorus in the soil, and make Invalid phosphorus is transformed into effective phosphorus, which promotes the absorption of phosphorus by roots; fulvic acid can absorb and store potassium ions, and increase the content of effective potassium, especially for potash fertilizer. Experiments show that fulvic acid can increase the utilization rate of nitrogen, phosphorus and potassium nutrients in fertilizers by more than 20%.
