For grapes, a high-quality mineral source potassium fulvate is very appropriate. In addition to the more than 12% organic potassium rich in the product itself, it can also promote the growth of grape roots, better absorb fertilizer and potassium around the plant, and improve the utilization rate of potash and other fertilizers, to meet the needs of grape plants for potassium throughout the grow
Humic acid and fulvic acid liquid appear dark brown or brown. If the concentration of liquid is too high or the atomization degree is poor, the water will often leave black spots on the fruit and leaves after evaporation.
Fulvic acid has a lower molecular weight, which is beneficial to the activation, capacity expansion, and desorption of heavy metals. Humic acid has a large molecular weight and the function of reduction and adsorption. It can reduce the availability of heavy metals.
Fulvic acid is an organic colloidal substance with the functions of water absorption and storage.
Humic acid can regulate soil acid and alkali. It can create a good growing environment for crop roots, improve soil structure and increase yield.
Mineral source fulvic acid is a small molecular organic compound extracted from lignite, which is the most valuable part of humic acid for agricultural production and soil remediation.
Due to humic acid having many times higher than soil salt exchange capacity, it can absorb a large number of ammonium ions, so as to reduce the loss.
Fulvic acid can affect the properties of soil and promote the formation of a more stable aggregate structure.
