2021 MOSES Organic Field Day

Organic Row Crops plus Prairie Restoration

Thursday, July 22 |  8:30 a.m. – 1 p.m. | Free 

St. Peter on the Prairie
24311 452 Avenue
Madison, South Dakota 57042


Charlie, Allan, Kevin, Jordan, and Aaron Johnson invite you to their annual farm tour where they will share with you their 45 years of organic grain farming practices. They will discuss and demonstrate use of rotations and other practices to maintain a productive, yet practical organic cropping system, addressing concerns such as weed control, fertility, storage, marketing, and more.

The South Dakota State University ag research team led by Melanie Caffe will provide background information on the organic oats variety trials they are once again conducting on the Johnson Farm. The trial site will be part of the tour. Learn more about the oat trials from the research story in the Organic Broadcaster.

In addition, farmer Tracy Rosenberg will speak about grasslands—South Dakota’s sister crop! Tracy custom grazes cow-calf pairs on 950 acres of grassland near Marvin, South Dakota. She is working to restore the grassland to its native prairie state.

This field day includes air-conditioned coach bus tour of the fields followed by free lunch.


Field Day Video Recaps:


Charlie Johnson

Charlie is the 2013 MOSES Organic Farmer of the Year. He operates 2,400 acres of certified organic corn, oats, soybeans, and alfalfa with his family near Madison, S.D. Johnson Farms also has a 200-head cow-calf operation. Charlie served on the board of the Northern Plains Sustainable Ag Society for six years, leading it for three. He currently serves on the MOSES Board of Directors. He is active in Dakota Rural Action, South Dakota Farmers Union, and local politics.


Aaron Johnson

Aaron has farmed with his cousins, Charlie and Allan, and now runs his own farm while maintaining close ties to them. Aaron and his family live on the same farm where he grew up. He farms 400 acres of tillable organic land, 85 acres of organic pasture, and 130 acres of tillable land that will be transitioned into organic.



Tracy Rosenberg

After selling her Iowa cropland, Tracy Rosenberg moved to South Dakota in search of native prairie. She rented nearly 1,000 acres of grassland from the monks of Blue Cloud Abbey with the intention of writing about environmental concerns, specifically the loss of biodiversity as a result of habitat degradation from rampant sod-busting. She later purchased the grasslands and became a “restoration grass farmer” on her native prairie range in Grant County’s pothole region, aptly named Abbey Grasslands of the Prairie.
