Prescribed Fire Effects on Soil Fertility

USDA Forest Service researcher John Butnor wondered how dormant-season prescribed fire affects forest soil fertility in the months after a burn. Do nutrients from burned pine straw, grasses, and woody debris remain in the forest? Others have studied soil a year or more after a prescribed burn. Butnor’s research compares soil chemistry before burning and 1, 3, 6, and 12 months after.
