MU Greenley Center field day set
Tours at Greenley Memorial Research Center traditionally feature research on crops, weeds and beef, but Randall Smoot, center superintendent, hopes to present some new things this year at the 32nd field day, Aug. 13. The University of Missouri research farm is in Knox County, one mile east of Novelty.
A new drainage system on farm plots and a wind-turbine tower are in the works. "We hope to have something to show," Smoot said. "If not, we will discuss design and display a prototype."
Wagon tours start at 8 a.m. In a lunchtime talk, Lori Wilcox, research and operations program director at the MU Food and Agricultural Policy Research Institute, will discuss cap-and-trade rules in the climate-change bill passed by the U.S. House of Representatives and now under consideration in the Senate.
The afternoon will feature drainage and subirrigation research at the Ross Jones Farm, located 11 miles southeast of Novelty on Highway 15.
With extensive rainfall the last two years, the drainage plots have proven their value, said Kelley Nelson, MU agronomist at the Greenley Center. The subsurface tiles carry off excess water in wet years; in dry years, the tiles can function in reverse, supplying irrigation to parched fields.
MU will let bids for addition of similar drainage and irrigation plots north of the Greenley headquarters. Smoot said he hopes to be able to show progress on the ground by the field day.
MU Extension weed specialist Kevin Bradley and graduate students will discuss new products for corn and soybeans, as well as management of glyphosate-resistant waterhemp and marestail. Farmers can see and compare the weed control.
MU weed scientist Reid Smeda will talk about management of volunteer corn. With new varieties resistant to herbicides, corn-in-corn control becomes a problem.
On the beef tour, Craig Payne, MU Extension veterinarian, will talk about new efforts to regulate livestock production.
Justin Sexten, nutritionist with the MU Extension Commercial Agriculture Program, will talk about nutritional considerations of weaned calves.
Zach Erwin, Extension regional livestock specialist, Monticello, Mo., will deliver a presentation titled "Forage Sampling, Analysis and Interpretations."
Another tour stop will examine feedlot results on steers from the Greenley beef herd, produced by high-accuracy sires.
The crops tour will highlight results of two experiments by students of MU soil scientist Peter Motavalli:
Pat Nash will describe nitrogen loss in cornfields, comparing slow-release nitrogen fertilizer to conventional urea fertilizer. The loss of nitrous oxide is a concern because of greenhouse-gas effects, Motavalli said. For the farmer, nitrogen loss can reduce corn yields.
John Shetley will describe his study of applying potassium fertilizer in cornfields at the same time as fungicide. "The idea is to control disease and at same time add needed potassium through the corn leaves," Motavalli said. The studies are being replicated at other MU research farms across the state.
Max Glover, Extension regional agronomist, Shelbyville, Mo., will present a talk titled "Diagnostic Services for Crops."
The field day is free and open to the public. Wagon tours will be repeated all morning, so people will be able to take part in all four tours, Smoot said.
