- Statement 1 is correct: Mulching creates a barrier that blocks sunlight from reaching the soil surface, which inhibits the germination and growth of weeds. - Statement 2 is incorrect: Mulching helps to retain soil moisture by reducing evaporation from the soil surface. It does not remove soil moisture; rather, it conserves it. - Statement 3 is correct: Organic mulches (like compost, bark, straw) decompose over time, providing food for soil microorganisms and earthworms, thereby increasing microbial activity, improving soil structure, and releasing nutrients. Even inorganic mulches can indirectly benefit microbial activity by maintaining more stable soil temperature and moisture conditions.
Mulching is a technique used to control soil erosion. Which among the following is/are advantages of mulching? 1. Reduces weed growth 2. Remove the soil moisture. 3. Encourages microbial activity in the soil.
