Crop scouting reports
Crop scouting is an essential part of integrated pest management (IPM). Scouting programs are designed to protect and maximize crop yield and quality while minimizing the risk associated with pesticide use.
Each week, extension agronomy specialists and agronomy assistants scout fields in Barton County and then report their findings through an automated phone service and email message. The message will go out to everyone signed up for the program.
The cost of the program is only $35 per phone number, $95 for three numbers, and $30 per phone number for those with 4 or more. For more information about the program, call the Barton County Extension Center at 417-682-3579.

Current weekly report
First crop soybeans nearing or at harvest
Jill Scheidt, agronomy specialist with University of Missouri Extension in Barton County, scouted fields northwest of Golden City, near Kenoma, Oct. 15 for the MU Extension crop scouting program
While out scouting fields, Scheidt says she observed that most first crop soybeans are nearing or at maturity stages.
“Soybeans are relatively easy to thresh, but the challenge is to get all the soybeans into the combine. Each four to five beans per square foot left in the field, either on the ground or in pods, means 1 bushel per acre loss. A loss of 2 to 3 percent is acceptable,” said Scheidt.
About 80 percent of harvest losses are associated with the combine header. Shattering is the most common loss and can occur if the cut too high, allowing low pods and branches to go unharvested.
“A recent survey of Missouri farms indicated an average 5 to 6 percent loss from cutting too high,” said Scheidt.
Scheidt says it is important to complete harvest as quickly as possible after beans first reach combine maturity. Late harvesting at low moisture content can cause high shattering losses.
“Soybeans give up and re-absorb moisture more easily than other crops. You can reduce shattering by harvesting soybeans when the relative humidity of the air is high,” said Scheidt.
For short-term storage (from harvest to about January), moisture content should be 13 percent or lower. For long-term, storage the moisture content should be 11 or 12 percent. If drying is necessary, natural air drying or air drying temperature rise of 10 degrees Fahrenheit or less is recommended to avoid cracking and loss of viability.
While field scouting Scheidt said she also observed second crop soybeans seeds’ turning color and that some were beginning to harden.
The weekly field scouting report is sponsored by University of Missouri Extension and Barton County Extension. For more information on this scouting report, or to learn how to receive it a week earlier by telephone, contact the MU Extension Center in Barton County, (417) 682-3579.
