This study evaluated the effects of two different mulches on soil and plant characteristics at the Umatilla National Forest, four years after a wildfire (Washington, U.S.). The results indicate that mulch application post-wildfire may increase soil moisture, promote microbial nitrogen mineralization, and/or increase biological nitrogen fixation, all of which would ultimately increase nitrogen availability.
