Mulching is an important agronomic practice that – A. Improves soil structure B. Increases runoff & soil losses C. Conserves moisture D. Increases soil erosion E. Facilitates infiltration

Correct option is C

The correct answer is (C) A, C & E Only

Explanation:
• Mulching is the process of covering the soil surface around plants to create more favorable conditions for plant growth and development.
• Statement A is correct: Organic mulches contribute organic matter to the soil upon decomposition, which significantly improves soil structure and aggregation.
• Statement C is correct: One of the primary purposes of mulching is to reduce evaporation from the soil surface, thereby conserving soil moisture.
• Statement E is correct: By preventing soil crusting and slowing down the speed of water droplets hitting the ground, mulching facilitates better water infiltration into the soil profile.

Information Booster:
• Mulching acts as a physical barrier that protects the soil from the kinetic energy of raindrops, preventing the detachment of soil particles.
• It helps in moderating soil temperature, keeping it cooler in summer and warmer in winter.
• Mulching can also suppress weed growth by blocking sunlight necessary for weed seed germination.

Additional Knowledge:
• Statement B is incorrect: Mulching actually decreases runoff by increasing the time water has to soak into the ground.
• Statement D is incorrect: Mulching is a key conservation practice used to decrease, not increase, soil erosion caused by wind and water.
