Fulvic Acid and Mineral Nutrients in Agriculture

In agriculture, fulvic acid is used in fertilizer formulations because it can form complexes with mineral nutrients such as iron, zinc and magnesium, helping keep them available in solution and in the root zone. SAINT HUMIC supplies fulvic acid for agricultural and industrial use only; our products are not supplied for human consumption, and this page does not describe effects in people.

Typical uses. Fulvic acid is commonly combined with micronutrient fertilizers, foliar sprays and fertigation solutions. Compatibility and application rates depend on the specific formulation and crop, so small-scale trials are recommended.

Product information. See our potassium fulvate and bio fulvic acid product pages, or contact us for the TDS and SDS of each grade.
