Which of the following effects are generally attributed to mulches, regardless of their material?

Show Answers

Inhibition of weed growth by limiting sunlight exposure on the soil surface, thereby preventing their germination and developmentProtection of soil from erosion, helping to maintain its structure and fertilityThermal insulation that promotes increased dew accumulation on the soilAll of the aboveNone of the above

Explanation

Mulches provide multiple benefits including suppressing weeds by reducing light availability which hinders their germination and growth, conserving soil by minimizing erosion, and offering thermal insulation that enhances dew deposition. Therefore, all of these effects collectively explain the role of mulches.
