Abstract: The invention provides in part a blended mulch product of at least two types of bio-degradable materials having different geometric shapes and physical properties. The first type of bio-degradable material may be a ligno-cellulosic fiber, such as a refined softwood ligno-cellulosic fiber, and the second type of bio-degradable material may be a wood-based flake, such as a processed wood residual.

Abstract: In one aspect there is provided a blended mulch product which can be mixed with water and spray-applied to a ground surface to form an erosion control medium, the blended mulch product comprising: about 75% to about 92% by weight ligno-cellulosic fibers; about 1% to about 10% by weight substantially straight synthetic fibers; and a tackifier; wherein the substantially straight synthetic fibers maintain their substantially straight form in the blended mulch product and the erosion control medium. Also provided are slurries in which the blended mulch product is mixed with water to produce the slurry, the slurry is spray-applied to a ground surface and the slurry dries on the ground surface to form an erosion control medium.
