Abstract
A degradable agricultural ground cover which is composed of high density polyethylene polymer fiber and cellulose pulp which is 100% photo and biodegradable for use in weed control and moisture retention in soil. The unique agricultural mat or cover lasts 8-12 weeks before serious photo and biodegradability occurs, while allowing crop plants sufficient time to mature and produce. The sheet totally disappears with plowing and tilling, becoming a soil extender until complete degradation occurs.
