Learning from droughts in the 1930s and ’50s

By Keith Harmoney, range scientist, Hays

I was recently asked how the drought of 2022 will affect forage growth in 2023 and how drought-stricken pastures should be managed during the fall and winter prior to next growing season.  These questions point me to results of a grazing study during the driest year on record at the KSU Agricultural Research Center at Hays in 1956.  Looking back at 1956 and nearly 80 years of grazing studies to date, the stocking rate study being conducted that year also produced the lowest pasture yields that have been recorded at the Research Center.

In fact, grazing animals were removed in August of 1956 from the high stocking rate treatment of the study because animals simply did not have enough forage left in pastures to graze through October, the time that animals were supposed to be removed according to the study protocol.  The heavy stocking rate pasture was essentially a tabletop.   However, the driest year on record at Hays in 1956 was followed the next year in 1957 by an above average season of precipitation.  In 1957, all of the pastures of the different stocking rate treatments in the study responded with above treatment average forage production from the above average precipitation, even in the heavy stocked pastures.

Forage response to fire intensity and time of burning

controlled burn

By Walt Fick, range management specialist

How does fire intensity impact plant response?  Fire intensity varies with the amount of vegetation to burn, moisture content of the vegetation, and weather conditions at the time of burning.  Last year was a good forage production year across most of Kansas, consequently there was plenty of plant material to burn in 2017.

The National Weather Service started issuing Red Flag Warnings back in February.  A Red Flag Warning indicates good conditions for extreme fire behavior.  This usually means relative humidity < 25%, wind speeds > 15 mph with frequent gusts > 25 mph, warm air temperatures e.g. >75oF, and 10-hour dead fuel moisture < 9%. Prescribed burning should not be conducted during a Red Flag Warning.
