Missouri Corn Growers Get Early Start This Year

Missouri farmers learned from last year’s planting season.
 
They are ahead of all other states in the nation for corn planting, according to the USDA Crop Progress Report. With rain predicted for the next two weeks, that’s a hopeful sign for the 2016 crop, says University of Missouri Extension agronomist Bill Wiebold.
 
Wiebold says that 2016 planting is far ahead of the five-year average for Missouri, with 58 percent of the Missouri corn crop in the ground.
 
Farmers remember being in the bull’s-eye of wet weather in 2015, when only 15 percent of the corn crop had been planted by the end of April, Wiebold says.
 
“Missouri corn growers jumped on it this year and took advantage of the good planting conditions,” says Greg Luce, MU Extension corn specialist.
 
MU Extension climatologist Pat Guinan says the April 12 map from the U.S. Drought Monitor shows abnormally dry conditions for much of the state and moderate drought in a few west-central counties. If notable rain events don’t occur soon, the lack of precipitation in April could become a liability for growers, he says.
 
Year-to-date precipitation departure from normal throughout the state is some of the highest in the country.  Missouri is currently into its fourth consecutive month of below-normal precipitation, Guinan says.

Field Talk Friday | Dr. John Murphy | Root Exudates, Soil Biology, and How Plants Recruit Microbes

Most of us spend our time managing what we can see above ground—plant height, leaf color, stand counts, and yield potential. But the deeper you dig into agronomy, the more you realize that some of the most important processes driving crop performance are happening just millimeters below the surface.

In this episode of Field Talk Friday, Dr. John Murphy continues the soil biology series by diving into one of the most fascinating topics in modern agronomy: root exudates and the role they play in shaping the microbial world around plant roots.

Roots are not passive structures simply pulling nutrients out of the soil. They are active participants in the underground ecosystem. Plants constantly release compounds into the soil—sugars, amino acids, organic acids, and other molecules—that act as both energy sources and signals for soil microbes.
