There's never been a better time to call for technical data and expert advice. ™ Without Mycorrhiza The eight different mulch treatments were replicated three times and randomly positioned within the plot layout on May 28, 2008. After being exposed to the elements for over 21 the mulch treatments were ignited on August 14, 2008. ⁄2 With Mycorrhiza 4881 NEO Parkway, Cleveland, OH 44128 1-800-926-4010 • 216-475-8488 fax: 216-475-6517 JRM Chemical, Inc. months, Based on cumulative values for the three combus- tion characteristics, shredded rubber, pine needles and shredded western red cedar demonstrated the most hazardous fire behavior. Composted wood chips and Tahoe chips (wood chips mixed with needles and bark) demonstrated the least hazard- ous fire behavior based on the factors measured in this evaluation. Shredded rubber mulch burned at the hottest aver- age maximum temperature (in excess of 630° F/332° C measured at 4 inches (10 cm) above the mulch bed) and produced the greatest flame heights which averaged over 3 feet (.91 m). It ignited easily and burned intensely for a prolonged period. Pine needles were second only to shredded rubber mulch in terms of the cumulative value of combustion characteristics.
