ABSTRACT:
Compositions and methods for concomitantly resisting fire and soil erosion. The compositions comprise an aqueous mixture of a polymer mixed with an organic material. The polymer preferably comprises polyacrylamide or a copolymer of polyacrylamide having anionic functional groups. The organic material comprises either cellulose, mulch and/or seed and mulch. The methods of the present invention comprise providing or forming an aqueous mixture of the compositions of the present invention and applying them to an area of land sought to be provided with soil erosion and/or fire resistant properties.
