Title: Investigation of Bark Residues for Livestock Bedding
Description:
Bark from aspen, a major timber products species in Wisconsin, Michigan, and Minnesota, has been generally too coarse as produced in commercial debarking for use without further processing. Methods of processing were studied, and a shredded product from a swing hammermill made in a relatively low bulk density was demonstrated to be highly suitable for livestock bedding at a low rate of application. Bark storage, necessary for farm or other bark use, was also studied. Finally it was found, in corn growth tests, that the total manure in bark bedding-manure mixtures more than offset the nitrogen-depleting effect on the soil of bark alone.
