🌱 How High Dissolved Oxygen Helps #Turfgrass on Golf Courses
✅ 1. Stronger Root Systems
• Roots need #oxygen to breathe (yes, even in waterlogged soil!).
• High DO in #irrigation water improves root respiration.
• This leads to deeper, denser root growth, which makes grass:
• More drought-resistant
• Better at nutrient uptake
• More resilient to wear from foot and cart traffic
✅ 2. Faster Nutrient Uptake
• With more oxygen, roots are more active.
• Nutrients like nitrate, phosphate, potassium, and iron are absorbed more efficiently.
• You may be able to use less fertilizer over time
✅ 3. Reduced Soil Compaction
• Oxygen-rich water helps beneficial microbes thrive.
• These microbes break down organic matter and keep soil loose and “alive.”
• This reduces compaction — a common problem on golf fairways and greens.
✅ 4. Disease Suppression
• Many turfgrass diseases (like root rot, Pythium) thrive in low-oxygen, anaerobic soil.
• High DO promotes aerobic microbial activity that naturally outcompetes harmful pathogens.
• Healthier turf with less chemical input.
✅ 5. Improved Water Penetration
• Oxygen-enriched water can reduce surface tension, allowing water to penetrate soil more evenly.
• This prevents dry spots and overwatering issues.
💧 Ideal DO Level for Golf Course Irrigation
• > 8 mg/L: Excellent
• 5–8 mg/L: Good
• < 5 mg/L: May start seeing issues with root health and disease
Systems using nanobubbles or oxygen injection can easily raise DO to 10–25 mg/L, leading to noticeable turf improvements
