Abstract
An organic substrate for controlling vegetation is manufactured from recycled waste paper, cotton fiber and cotton gin waste, and gypsum. The recycled waste products are combined to form a slurry mixture for processing by conventional paper making machinery into a substrate that may be used in sheet form or comminuted pieces to control weed growth in horticultural applications and serve as a carrier substrate for germinating seeds and growing select vegetation species.
