It has been the typical Missouri weather pattern, two days with temperatures in the 80s and then three days of temperatures dropping into the 50s. And while there is plenty of precipitation, one University of Missouri forage specialist says it will take more warm weather to obtain optimal growth of pasture grasses.
While there are some pastures greening up across the state, these fields are not putting on the pounds of dry matter needed by the state's graziers. In fact, some livestock producers are still feeding winter hay.
Rob Kallenbach, University of Missouri forage specialist, says he hears two frequent complaints: The grass is not growing. And there are more weeds than usual.
Warm weather needed
He says the first complaint is a result of the cool spring. For pasture grasses to grow there needs to be warm sunshine, he explains. Right now, there is plenty of moisture in the soil to support growth, but grey, overcast days do not facilitate plant growth.
He says farmers across the state are finding one-third the growth of just one year ago in grazing paddocks. Last April, they were reporting growth averaging 90 pounds of dry matter per day per acre. This year, growth is less than 30 pounds per day.
Kallenbach says with warm weather pastures will jump up quickly. Sugars from photosynthesis make rapid growth. However, he warns that if livestock producers have been grazing cattle on depleted pastures all spring it may be a slower recovery. Cattle nip off leaves that create energy for regrowth.
