Autumn burning in Kansas tallgrass prairie caused greater postfire productivity than spring burning. This result is consistent with the hypothesis that warmer spring soil temperatures stimulate growth of the grasses. Spring and autumn burned plots had similar microclimates. It is possible that different results obtained in similar ecosystems are due to the influence of grazing, properties of different soils and soil decomposer communities, and different prefire nutrient status</p>10atallgrass prairie1 aJames, S.W.  uhttp://knz.lternet.edu/content/unexpected-effect-fall-burning-soil-organic-matter-tallgrass-prairie
