Biostimulants
Fulvic Acid
Fulvic acid is a low-molecular organic compound that belongs to the humus fractions in the soil. Within biostimulants, fulvic acid is used because of its high biological activity and its ability to support nutrient uptake, transport, and physiological efficiency of plants.
What is fulvic acid?
Fulvic acid arises from the decomposition of organic material and is soluble over a broad pH range. Due to its small molecular size, fulvic acid can easily interact with both soil particles and plant cells.
- Low-molecular and biologically active
- Soluble in water at all pH levels
- Part of natural humus substances
- Suitable for root and foliar application
Fulvic acid in the soil–root interface
In the soil, fulvic acid plays an important role in mobilizing nutrients. It forms soluble complexes with minerals, making them more readily available for uptake by roots.
Chelation and nutrient uptake
One of the main properties of fulvic acid is chelation. By binding micronutrients, they remain stable and absorbable, even under unfavorable soil conditions such as high pH or salt stress.
Effects of fulvic acid in the plant
Improved uptake efficiency
Fulvic acid supports the transport of nutrients through cell membranes and promotes an even distribution within the plant.
Support of metabolic processes
Due to improved availability of essential elements, the plant can carry out its physiological processes more efficiently.
Stress support
Under abiotic stress conditions, fulvic acid contributes to maintaining metabolic activity and plant vitality.
Fulvic acid in biostimulant formulations
Fulvic acid is often used as a functional component in biostimulants due to its high compatibility with other raw materials and its wide applicability.
- Combinable with micronutrients
- Suitable for foliar and root application
- Supporting uptake and stress claims
- Usable in diverse cultivation systems
Effect on plant performance
Correctly applied fulvic acid contributes to:
- Improved nutrient uptake
- Higher physiological efficiency
- Better stress tolerance
- Increased plant vitality
