Abstract: A method of securing and covering a windrow-shaped stack of material to the ground includes the steps of laying a cover sheet over the entire stack and placing ballast around the base of the stack over the edges of the cover sheet to hold the sheet down. A plurality of anchors pairs are positioned on opposite sides of the stack, with flat adjustable-length side straps secured laterally over the sides of the stack from side anchor to side anchor. Anchor pairs are also positioned along the sides of semi-circular ends of the base of the stack, with flat adjustable-length end straps secured laterally over the ends of the stack from end anchor to end anchor. In addition at least one second end strap is also secured lateral over the end of the stack, but is secured at its ends to the first opposed pair of side anchors along the sides of the stack.
