Abstract
Accelerated degradation of mulching paper, formed from cellulose fibers impregnated with a hydrophobic resin to provide weather resistance, comprises spraying the paper with an enzyme solution which degrades both the resin and the cellulose.
Claims12
A mulching process comprising
- depositing over a growing area a mulching paper comprising cellulose fibers impregnated with a hydrophobic resin, giving the mulching paper a weather-resistant character;
- growing and harvesting a crop in the growing area;
- spraying onto the mulching paper an enzymatic solution capable of degrading both the resin and the cellulose fibers;
- and
- plowing the growing area to bury the mulching paper, whereby the mulching paper is degraded at an accelerated rate.
