Mulching Techniques to Retain Soil Moisture in Summer

Mulching Techniques to Retain Soil Moisture in Summer

Summer farming in India brings serious challenges—high temperatures, rapid evaporation, soil moisture loss, and heat stress on crops. One of the most effective and low-cost solutions to tackle these problems is mulching.

Mulching helps farmers conserve water, protect soil health, and improve crop yield during the harsh summer season.

🌱 What Is Mulching?

Mulching is the practice of covering the soil surface around plants with organic or inorganic materials to reduce moisture loss and regulate soil temperature.

It acts as a protective layer between the soil and the environment.

☀️ Why Mulching Is Important in Summer

During summer:

• Soil moisture evaporates quickly
• Soil temperature rises
• Weeds grow rapidly
• Irrigation costs increase

Mulching helps solve all these issues by creating a cool and moisture-rich root zone.

🌿 Benefits of Mulching in Summer

💧 1. Reduces Water Evaporation

Mulch significantly reduces moisture loss, saving up to 30–50% irrigation water.

🌡 2. Regulates Soil Temperature

It keeps soil cooler during hot days and prevents root damage.

🌱 3. Controls Weed Growth

Mulch blocks sunlight, preventing weed germination.

🌾 4. Improves Soil Health

Organic mulch decomposes and adds nutrients to the soil.

💰 5. Reduces Irrigation Cost

Less frequent watering means lower electricity or diesel expenses.

🍂 Types of Mulching Techniques

🌿 1. Organic Mulching (Natural & Low-Cost)

Organic materials decompose over time and improve soil fertility.

Common Materials:

• Straw
• Dry leaves
• Crop residues
• Sugarcane trash
• Grass clippings
• Coconut husk

Best for: Vegetables, fruit crops, and small farms.

🛡 2. Plastic Mulching (Poly Mulch)

Plastic sheets are spread over the soil surface, with holes for planting.

Advantages:

• Excellent moisture conservation
• Strong weed control
• Suitable for commercial vegetable farming

Common Colors:

• Black (weed control)
• Silver-black (repels insects)

Best for: Tomato, chilli, watermelon, cucumber, strawberry.

🌾 3. Live Mulching

Growing cover crops between main crops to protect soil.

Examples:

• Cowpea
• Green gram
• Clover

It prevents soil erosion and improves fertility.

🌳 4. Mulching in Fruit Orchards

Apply 5–10 cm thick organic mulch around trees like:

• Mango
• Pomegranate
• Guava
• Banana

Keep mulch slightly away from the trunk to avoid fungal infection.

🚜 How to Apply Mulch Properly

1. Irrigate field before mulching
2. Remove existing weeds
3. Spread mulch evenly (5–8 cm thick for organic materials)
4. Ensure proper drainage
5. Monitor for pest buildup

Proper application ensures maximum benefit.

🌍 Crops That Benefit Most from Mulching in Summer

• Tomato
• Chilli
• Brinjal
• Watermelon
• Cucumber
• Papaya
• Banana
• Cotton

Mulching is especially useful in water-scarce regions.

📉 Common Mistakes to Avoid

• Applying too thick mulch layer
• Placing mulch directly against plant stem
• Ignoring pest monitoring
• Using diseased crop residue

🌟 Additional Tips for Summer Moisture Conservation

• Combine mulching with drip irrigation
• Use early morning irrigation
• Practice crop rotation
• Improve soil organic matter

✅ Conclusion

Mulching is a simple yet powerful technique to retain soil moisture during the summer season. It reduces water use, controls weeds, improves soil health, and boosts crop productivity.

For small and marginal farmers, mulching is a cost-effective solution that turns summer challenges into profitable opportunities.

Adopting proper mulching techniques can help farmers achieve higher yields with lower water input—making farming more sustainable and climate-resilient.
