WEST LAFAYETTE, Ind. (WISH) - Indiana Wheat producers are concerned about their crop due to wild temperature changes this winter.
Temperatures in recent weeks have risen to between 50 and 60 degrees and then dropped to single digits.
Purdue Extension Agronomist Shaun Casteel says moisture in soil expands in cold temperatures and contracts when it thaws and the soil becomes unleavened. Plant roots become exposed and lack access to moisture.
Casteel said there hasn't been a lot of snow this season, and wheat is left exposed to the extreme temperatures.
"A lot of wheat fields no longer have a blanket of snow for insulation, and they're exposed to the cold weather," Casteel said. "That's going to cause some potential leaf burning."
Wheat producers will have to evaluate their crop to see if they need to adjust the rate of a nitrogen application – something that will help improve tiller numbers and yields.
