Abstract
A compost filter netting comprises plastic netting formed in a tube having a diameter of 6″-36″ wherein the plastic netting includes netting openings of ⅛-⅜″ and configured to be filled with compost to form a compost filter sock, wherein the linear length of the compost filter sock is not less than 93% of the linear length of the originally manufactured empty compost filter netting. A method of forming a compost filter sock using the compost filter netting and the compost filter sock made thereby is disclosed. The compost filter netting substantially eliminates the problem of miscalculation of shrink rate that is problematic for in field applications.
