Abiotic stress is the negative impact of nonliving factors and can lead to biotic stress. Abiotic stress is caused by four fundamental factors: weather, soil health, nutritional imbalances, and oxidative stress. Turfgrass quality and performance are reduced when abiotic stress occurs.

Turfgrass naturally produces antioxidants to counteract stress. Turf must constantly adapt to the growing conditions of its environment. As stress occurs, oxygen free radicals accumulate in plant tissue. If the turfgrass is unable to combat the oxygen free radicals, premature cell degradation occurs. Redox technologies promote abiotic stress defense.

Examples of Abiotic Stress Factors:
- Inhibited Plant Respiration
- Reduced Photosynthetic Activity
- Poor Root Growth & Metabolism
- Weak Cell Wall Strength
