On the other hand, inorganic mulches may be natural products such as volcanic rock, gravels, stones, or pebbles. They can also consist of human-made materials such as rubber or plastic pulverized ground tires, fabric sheets, or inert materials from non-plant components or even rocks.

In comparison, organic mulches provide better benefits than inorganic mulches do. Also, organic mulches decompose easily, enhancing the soil’s quality, increasing beneficial soil components.
