Sawdust and, to a lesser extent, wood chips deplete soil nitrogen, if worked into the soil. Mulch protects soil from being eroded and reduces water runoff by providing a “sponge” surface that slows and absorbs water. Reduces root competition. In the Midwest, most of a tree’s fine roots are in the upper 12 to 18 inches of soil.
