Organic Acids
Organische zuren are low-molecular compounds that play an important role in soil processes and the internal metabolism of plants. Within biostimulants, organic acids are used to improve nutrient availability, increase physiological efficiency, and support stress responses.
What are organic acids?
Organic acids (Organic Acids) are carbon-containing acids that are produced both by the plants themselves and by microorganisms. They naturally occur in the soil, root environment, and in plant cells.
- Low-molecular and biologically active compounds
- Soluble and fast-acting
- Involved in metabolic and chemical processes
- Widely applicable in biostimulant formulations
Role of organic acids in the soil
In the soil, organic acids influence the chemical availability of nutrients. They can mobilize and bind minerals, making them more accessible for uptake by the root system.
Nutrient mobility and uptake
Organic acids contribute to the dissolving and releasing of nutrients, especially micronutrients that are difficult to access under certain soil conditions.
Effects of organic acids in the plant
Support of metabolic pathways
Within the plant, organic acids are part of central metabolic cycles and support energy production and carbon conversion.
pH regulation and ion balance
Organic acids help regulate pH in cells and tissues and contribute to a stable ion balance.
Stress support
Under abiotic stress, organic acids help keep metabolic processes active and limit the disruption of physiological functions.
Organic acids and root activity
Through root excretion, organic acids influence the rhizosphere, which can lead to better nutrient availability and a more active root system.
Organic acids in biostimulant formulations
Organic acids are often added as functional components due to their fast action and good compatibility with other raw materials.
- Support nutrient uptake and mobility
- Suitable for foliar and root application
- Combine with fulvic acid and micronutrients
- Widely applicable in various crops
Effect on plant performance
Correctly applied, organic acids contribute to:
- Improved nutrient availability
- More efficient metabolism
- Better stress tolerance
- Increased plant vitality
