The present invention relates to a process for restoring disturbed arid land soil crust. According to the process, site-sourced biological soil crusts (BSC) serve as sources for liquid suspension inoculants onto degraded arid lands. The BSC are gathered from near the disturbed site, and organisms from them are cultured, replicated and multiplied many times, preferably off-site. Then, this inoculant resulting from the indigenous population is distributed live and active in a liquid suspension over the entire area of the disturbed site.
