The Southwest Ohio Corn Growers Agronomy Field Day in Fayette County today had a large crowd and a diverse array of topics.
There was quite a bit of interest in the Precision Hawk unmanned aerial vehicle (UAV) being demonstrated. The small UAV captures aerial images to provide extensive information that has endless on-farm applications. Tyler Collins with Precision Hawk said the planes can be used to assess plant health, tile, diseases, weed pressure and crop development. The plane is completely computer operated and costs around $25,000.
“Planting depth is a management practice that does not always get a lot of respect. When it comes to planting depth we typically have an all purpose recommendation of an inch and a half to two inches,” Thomison said. “Probably 90% of the time it works. But there are occasions when we have weather extremes or situations where there is a need to adjust planting depth.”
Deeper planting may be recommended as the season progresses and soils become warmer and drier. Planting shallower than 1.5 inches is generally not recommended at any planting date or in any soil type.
Recent studies comparing planting depths that are within the depth ranges commonly used by growers
are limited, and none have attempted to compare hybrid differences to varying planting depths. Hybrids with higher levels of drought tolerance may provide improved yield stability in shallow planted situations while also providing improved performance at normal planting depths, though this has not been documented.
Attendees also got to hear from Dave Martin from Bluegrass Farms about the increasingly important Asian food grade soybean market, OSU Extension specialist Jim Hoorman who covered soil health and OSU Extension entomologist Andy Michel who talked about the future of pest management.
Field Day visitors also got to ride in a plane and survey their fields from the sky in a plane the took off from the airport at the site of the event.
