Abstract
A novel agricultural mulch and improved method of arranging the mulch on a growing field with furrows is disclosed wherein the mulch is made of an extensible paper substrate having a top surface and a bottom surface with side sections near the edges of the substrate capable of being turned up and bent back over the top surface of the paper substrate as the mulch is laid down over the growing field; the bottom surface of the paper substrate will be exposed for receiving soil from the field to anchor the mulch and protect it against the weathering of rain, sun and wind.
