Mulch has provided a means of mitigating the effects of erosion for decades, based on the benefits associated with hydromulching for revegetation. It is commonly applied using purpose-built HydroRigs™ to hydraulically disperse mulch with water, seed, and fertilisers, onto disturbed soil or steep slopes, to avoid excess loss of sediment. Depending on the site characteristics, additives and binders can be included to underpin vegetation growth.
