PRODUCT DESCRIPTION

Fulvic acid is a component of humic acid. Humic acid widely exists in peat, lignite, weathered coal, etc. in nature. A certain amount of fulvic acid and potassium oxide can be extracted from humic acid to make potassium fulvic acid.

Leonardite Potassium Fulvate Flake is a pure natural mineral active potassium fertilizer. Potassium fulvicate contains trace elements, rare earth elements, plant growth regulators, virus inhibitors and other nutrients, making the nutrients more adequate and the supply more reasonable. , thus avoiding the occurrence of various physiological diseases caused by the lack of elements in crops, making the crops more vigorous, the leaf color darker, and the lodging resistance stronger.

Water Solubility：100%
Fulvic Acid (dry basis)：≥50%
Potassium (K2O dry basis)：≥12%
Organic matter (dry basis)：≥75%

PRODUCK FUNCTION

Leonardite Potassium Fulvate Flake can activate hardened soil, promote the physiological metabolism of various fruits, vegetables and field crops, and promote root development and lush stems and leaves. Potassium fulvicate can be used as base fertilizer, flush fertilizer or top dressing to save various fertilizers. It can extend the freshness period and picking period of fruits and vegetables, prevent flowers and fruits from falling, increase the sugar content of fruits, and improve the quality of fruits.

Leonardite Potassium Fulvate Flake in an alkaline soil environment, many basic elements and trace elements exist in forms that cannot be absorbed by plants. Humic acid can buffer the pH, thereby converting these basic nutrients and trace elements. Converted into a form that can be absorbed by plants. In an acidic soil environment, it can react with heavy metals to reduce heavy metal pollution. At the same time, the phosphorus fixed by Ca3+Fe3+Al3+ in the soil can also be released and absorbed by plants. In soils with high salt content, potassium fulvic acid, a mineral source, can replace nutrients through salt exchange capacity and be absorbed by crops.

Leonardite Potassium Fulvate Flake from flake mineral sources has a large number of negative ion functional groups, which can increase the cation exchange capacity of the soil and promote the movement of nutrients in the soil. At the same time, potassium fulvicate itself is a carbon source, providing carbon nutrients to the soil and promoting the activities of beneficial soil microorganisms. The microorganisms and organic matter in the soil work together to improve the soil, making the soil more suitable for the growth of crops.
1. Fulvic acid ions have strong viscosity and adsorption properties, and can adsorb and stick clay particles in the soil together to form relatively large aggregates. The more pellets there are, the more breathable the soil is and the more vigorous the root system will grow.
2. The ionic functional group of Leonardite Potassium Fulvate Flake, a flaky mineral source, has a strong adsorption function for water molecules. It can absorb 3 times its own weight and enhance the water retention capacity of the soil.
3. Leonardite Potassium Fulvate Flake, a flake mineral source, can release phosphorus fixed by trace elements in the soil, improve the utilization of phosphorus, and promote rooting. Fulvic acid can also quickly activate the growth mechanism of crop roots, promote the growth of new roots and capillary roots, and make the roots thick, strong and hairy. Miaoqi can germinate 1-3 days earlier and increase the emergence rate by 10%-25%.
4. Fulvic acid can release negative oxygen ions, reduce inflammation, sterilize, repair cells, and treat root rot. Passivates heavy metals in the soil and prevents crops from dying and rotting.

It is suitable for flushing, spraying, drip irrigation and soilless cultivation. It can be applied alone or mixed with nitrogen, phosphorus and potassium. The interval between each use is about 15 days.
