Frequently Asked Questions

What are the benefits of fulvic acid in agriculture?

Fulvic acid enhances nutrient uptake, improves soil structure, stimulates root development, and increases plant resistance to stress. Its small molecular size allows for rapid absorption through roots and leaves.

How does your ultra-fine powder technology improve performance?

Our ultra-fine powders with ≤5% moisture content dissolve instantly in water, preventing clogging in drip irrigation systems and ensuring uniform application. This maximizes bioavailability and crop response.

Are your products suitable for organic farming?

Yes, our bio-organic stimulants are derived from natural sources and are compatible with most organic farming standards. We recommend checking with your certification body for specific compliance.

What is the difference between humic acid and fulvic acid?

Humic acid has larger molecules and works primarily in the soil to improve structure and nutrient retention. Fulvic acid has smaller molecules that are more readily absorbed by plants, enhancing nutrient transport and metabolic processes.
