Abstract: A modified method of measuring litter decomposition using mesh bags is suggested in which the bags are reused during several time increments. The chief objections to this method are that litter may be lost through spillage and that repeated artificial drying may affect decomposition rates. Experimental results are presented to show that spillage represents a significant source of error with finely divided litter, even using conventional litter bag methods. A method for handling litter bags is suggested in which corrections may be made for spillage. In a second experiment it was found that decomposition rates were not significantly altered by repeated artificial drying of old-field litter so that repeated drying of litter in field experiments may be valid. |
