BLOOMFIELD, Iowa (Sept. 1, 2022) — Tim Dotterer will host a Practical Farmers of Iowa field day exploring a range of cover crop practices – including grazing cover crops, use of a high-capacity drone to seed and spray, cover crop mixes and more – on Friday, Sept. 9, from 11:30 a.m. to 2 p.m. near Bloomfield (15601 285th St.).

The event – “Drones, Extended Rotations and Cover Crop Grazing in Bloomfield” – is free to attend and will include lunch from 11:30 a.m. to noon. Sign up online, or call Debra Boekholder at (515) 232-5661. The field day is sponsored by Byron Seeds/Martin’s Farm Service, Davis County Corn Growers Association and Sinclair Tractor.

Location note: The farm is 5 miles west and 7 miles south of Bloomfield. From U.S. 63 south, turn right (west) onto 285th Street. The farm is the first on the south side.

Tim raises conventional corn, conventional and non-GMO soybeans, small grains and rye for seed. He uses cover crops to build soil health and provide extra forage for his cattle and backgrounding calves, and sells his extra rye to farmers directly after cleaning at a local grain cleaner.

Curious about trying new equipment and production practices, Tim recently acquired a high-capacity drone for seeding cover crops and spraying and experimented with legume cover crop mixes hoping to reduce synthetic nitrogen inputs.

During the field day, guests will have a chance to learn more about those practices and the various ways Tim incorporates cover crops and small grains into his crop and cattle enterprises. Topics to be discussed include:

  • Wheat and rye production for on-farm use
  • Harvest and fertilizer equipment
  • Drone seeding and spraying
  • Rye production for cover crop seed
  • Grazing cover crop mixes
  • Spring and fall covers
  • Cover crop and forage variety selection
  • Small grains variety selection

Clair Martin, with Byron Seed, will also speak during the field day. Full event details are available at
