Description
FULVIC ACID
Hollow Structure Microgranule(Spray dried powder)
is a short carbon chain material extracted from natural leonardite with high load capacity and physiological activity. The amount of Oxygen-containing functional groups of mineral-source fulvic acid is more abundant than other humic acid series products and it has higher physiological activity. As a broad-spectrum plant growth regulator, mineral-source fulvic acid can promote plant growth, increase crop yield, improve crop quality, and appropriately control the opening degree of leaf stomata to reduce transpiration so improve drought resistance and resist adversity ability. In addition, the carbon in the mineral-source fulvic acid is relatively stable and is not easy to be decomposed by microorganisms so it has long-term effects.

Application
Agriculture and Reference Dose: Mainly used directly for spray irrigation, drip irrigation, and liquid organic fertilizer as plant growth stimulants and fertilizer promoters.
★ Chelating nutrients to make fertilizer more efficient.
★ Increasing anti-waterlogging ability, drought resistance, and preventing diseases of plants.
★ Stimulating the microbiological activity of plants.
★ Slow-releasing fertilizer, improving the utility of fertilizer and pesticide.
★ Increasing nutrient absorption, promoting the germination and growth of plants.
★ Accelerating the precipitation and decomposition, improving the soil structure.
- Fertigation: 1 - 2 kg per hectare or based on local conditions
- Foliar: 300 g - 1 kg per hectare
- Soaking (seeds, root): 10 - 24 hours in 2000 times solution. It can shorten the soaking hours when the temperature is high.
- Recommended total amounts in liquid fertilizer: 3% - 8% min
Packaging and Storage
25 KG kraft bag with PE liner, bulk bag, or as your request.
Store in a sealed and cool dry place.
