Potassium Fulvic Acid

      Fulvic acid is a humic substance that is able to improve soil quality and increase crop growth performance by making nutrients more available.Potassium Fulvic Acid liquid fertilizer This is accomplished by a process called chelation, where molecules bind to minerals in the soil to make them more accessible for plant uptake. It is also highly water soluble, so it is easily incorporated into the soil. Fulvic acids are found in humus, which is the organic component of soil that makes it fertile.

      Unlike most other fertilizers, Potassium Fulvic Acid liquid fertilizer is easily dissolved in water with a pH between 1-14. This high soluble concentration allows for easy and direct application at planting, sidedress, foliar, or through irrigation. Fulvic acid is a natural fertilizer, so it does not degrade rapidly in soil and can be used for decades.

      Potassium Fulvic Acid fertilizer promotes plant roots, stems, flowers, and fruits, and increases the yield of vegetables and fruit crops. It also increases the amount of phosphorus and potassium absorbed by plants, and enhances the utilization rate of these nutrients. In addition, fulvic acid increases soil water holding capacity and decreases water evaporation.

      Fulvic acid can increase the utilization rate of nitrogen, phosphorus, and potassium in fertilizers by more than 20%. It can also promote the synthesis of proteins in plants, which helps with photosynthesis. It can also reduce the loss of ammonium nitrogen, promote phosphate mobility in the soil, and convert ineffective phosphorus into effective phosphorus. It can also stimulate and regulate the physiological metabolism of crops, thereby increasing the uptake of potassium ions by up to 30%.

      In addition, fulvic acid has excellent complexation and chelation properties. It can bind to several trace elements and metals, such as iron, zinc, and copper. It can react with these elements to form a sulfate trace element chelate compound with good solubility, such as fulvic acid-Zn and fulvic acid-Mn, which are more easily absorbed by plants than their non-chelated counterparts.

      This research demonstrates that co-application of N fertilizer and fulvic acid significantly improved grain yields, reduced N leaching losses, and enhanced the availability of soil mineral N and Olsen-P in salt-affected soils. It is therefore an effective treatment strategy for enhancing crop productivity and alleviating environmental degradation.
