Compost mulch has been compared with topsoil and subsoil as a media for crop growth and weed suppression during revegetation of highway right-of-ways. In this study compost was shown to be as effective as topsoil and subsoil controls for crop growth, while significantly reducing growth of weed species. There were no significant differences between 5 and 10 cm depths of compost application, indicating that the shallower depth would be adequate for most situations. Compost mulches offer promising opportunities for crop and weed management during revegetation of roadsides and other disturbed landscapes.
