Abiotic stress in crops – how to protect plants from drought, frost and waterlogging?
Abiotic stresses such as drought, frost and excess water can reduce crop yields by 30–50%. Therefore, it is crucial to prepare plants before stress occurs, rather than reacting only after damage appears. In agricultural practice, this can be supported by using anti-stress fertilizers, such as VitaExpert Stress Control, which supplies components that help strengthen plant resilience.
VitaExpert Stress Control – proline and potassium
Proline – support for natural defense mechanisms
Proline is an amino acid that acts as an osmoprotectant in plants. It:
- stabilizes cell membranes,
- protects proteins and enzymes,
- regulates the osmotic potential of cells,
- activates defense mechanisms under stress conditions.
As a result, it helps plants better tolerate unfavorable environmental conditions.
Potassium – regulator of water management
Potassium plays a key role in plant water balance. It:
- regulates stomatal activity,
- improves water retention in plant tissues,
- reduces excessive transpiration,
- strengthens cell walls.
Synergistic action of VitaExpert Stress Control
The combination of proline and potassium supports plants under stress conditions:
- drought – improved water retention and maintenance of cell turgor,
- frost – protection of cell membranes and increased tolerance to low temperatures,
- waterlogging – faster plant recovery.
When to apply VitaExpert Stress Control
- 7–10 days before expected stress
- during critical growth stages of plants
- after stress, to support faster regeneration
Dosage: 1.5–3 L/ha depending on crop type and stress intensity.
