Which of the following statement are advantages of mulching? It I. controls weeds II. conserves soil moisture III. increases soil temperature IV. reduces soil pH

Answer Details

The correct answer is: I and II only. Mulching is a farming practice where organic or inorganic materials are placed on top of the soil surface. One of the advantages of mulching is that it helps to control weeds by depriving them of sunlight, which they need to grow. Mulching also helps to conserve soil moisture by reducing evaporation from the soil surface. This helps to maintain a steady supply of moisture for crops to grow. However, mulching does not increase soil temperature and does not directly affect soil pH.
