A STANDARD CURVE FOR INTER-SITE COMPARISON OF CELLULOSE DEGRADATION USING THE COTTON STRIP METHOD
Cotton cloth was buried in contrasting soils for various lengths of time until close to physical disintegration. Cellulose degradation was assessed by comparing the tensile strength of cloth after recovery with that before burial. A curve was derived for loss of tensile strength of cloth, when rotti...

Cotton cloth was buried in contrasting soils for various lengths of time until close to physical disintegration. Cellulose degradation was assessed by comparing the tensile strength of cloth after recovery with that before burial.
