ABSTRACT:
Agricultural mulch sheeting which provides soil moisture retention and weed control during the growing season, yet is readily degradable when harrowed into the soil after harvest, comprises a creped natural kraft paper coated on both sides with a polyvinylidene chloride latex dispersion. The coating on one side of the sheet includes carbon black which provides the opacity to prevent weed growth while also yielding a reversible sheet which may be installed to absorb or reflect the sun's rays. The mulch may also include a sleeve of the same material sealed to the upper surface of the main sheet to form a conduit for irrigating water which seeps into the underlying soil through a row of puctures in the sheet.
