The correct answer is D. Mulching is a practice that helps to conserve soil moisture, regulate soil temperature, and suppress weeds.
Mulching helps to conserve soil moisture by preventing evaporation. The mulch acts as a barrier between the soil and the sun, which helps to keep the soil cooler and moister. This is especially important in hot, dry climates.
Mulching also helps to regulate soil temperature. The mulch helps to insulate the soil, which helps to keep the soil cooler in the summer and warmer in the winter. This is important for plants that are sensitive to temperature changes.
Mulching also helps to suppress weeds. The mulch creates a barrier between the soil and the sunlight, which prevents weeds from germinating. This can save you time and money on weed control.
In addition to these benefits, mulching can also improve soil structure, reduce erosion, and provide habitat for beneficial insects.
