Law enforcement officials have sought arson arrests in several of the fall fires, which burned through more than 516,000 acres, killing seven people and injuring nearly 90.
Summer and fall fire reduce silica content from 7.0%to4.1%and4.3%4.3%, respectively.
Summer and fall fire reduced active buds by 42% relative to nonburned plots.
Under dry postfire growing conditions, purple threeawn current-year biomass was reduced 73%and5858% with summer and fall fire, respectively.
Purple threeawn IVOMD increased by 14.0% and 13.0% following summer and fall fire, respectively, compared to nonburned plots.
Fire (no fire, summer fire, fall fire) and rate of nitrogen addition (0, 46, 80 kg N·ha-1) were arranged in a completely randomized, fully factorial design.
However, total number of buds per tiller was greater with nitrogen addition following fall fire and increased with each increase in nitrogen following summer fire.
In vegetative stages, summer and fall fire increased CP from 6.2% to 12.1% and 13.0%, respectively, and NDF decreased from 72.1% to 69.4% and 68.2%, respectively.
When postfire growing conditions were wet, current-year biomass of purple threeawn was reduced 90%and7373% with summer and fall fire, respectively.
That means everything in the game can be burned, exploded, melted and so on — dirt will fall, fire will spread, water (and acid, and lava) will flow and escape its container.
The resulting wildfire, eventually stretching 11,000 hectares and burning for 6 weeks, marked an early start to the record-breaking fall fire season that the southeastern United States experienced this year.
