Kansas State University researchers have concluded that the decades-long practice of Kansas ranchers burning grassland in late April could take place virtually any time with no ill effects.

E. Gene Towne and Joseph Craine based their research on 20 years of data collected from burning at the Konza Prairie Biological Station south of Manhattan.

They say grass composition and production were not negatively affected by burning in the fall or winter.

That's contrary to research from more than 40 years ago that suggested grass had to be burned in late spring.
