Microbiology

A new and exciting step in rebuilding healthy soil is managing for soil microbial communities. The soil environment is like any other ecosystem — it consists of producers, consumers, and predators. Bacteria and fungi make up the producers, beneficial protozoa and nematodes are the consumers, and the top predators are arthropods and predatory nematodes. This production and consumption model contributes to nutrient cycling in the soil. Due to past agricultural practices, most soil consists solely of bacteria.

To introduce more beneficial organisms and balance fungi-bacteria ratios, some farmers are turning to biodiverse, aerobic composting methods to inoculate their crop fields and pastures. This is a developing piece of work, so please check out the information below and continue to check back for more resources as they emerge.

LSP Johnson-Su Research Video Reports

Videographer Kobi Dansingburg recently created two reports on the on-farm research LSP conducted in Minnesota and Wisconsin over a two-year period related to developing compost using the Johnson-Su Bioreactor System.

Presentation on Johnson-Su Bioreactor System

On Aug. 26. 2022, LSP hosted David Johnson and Hui-Chun Su Johnson on the Pangrac dairy farm near Lewiston, Minn. The Johnson’s gave a presentation on the Biologically Enhanced Agricultural Management System, otherwise known as BEAM. They also discussed the use of the Johnson-Su Bioreactor Composting system to build soil biology. Check out their presentation here.

Storytelling for Sales: Digital Marketing Best Practices to Get Your Farm’s Next Customer is designed to help farmers grow their customer base by sharpening their storytelling and digital marketing skills—whether they’re selling through farmers’ markets, CSAs, or direct-to-retail. This Greener Pastures and Meet the Minnesota Makers workshop will cover how websites and social media can actually convert viewers into buyers to creating content that builds community loyalty.

This workshop is also designed for ag educators, professionals, and partner organizational staff who support farmers directly and want to be well-versed on the marketing best practices to support direct-to-consumer farms.

Wednesday June 25

2:00 pm – 5:00 pm
LSP-PFI Grazing Field Day at Hoosier Ridge Ranch
Wednesday June 25
2:00 pm – 5:00 pm
LSP-PFI Grazing Field Day at Hoosier Ridge Ranch
Hoosier Ridge Ranch, 15998 Wabasha County Rd 26, Altura, MN 55910, USA

Over the last 50 years, livestock have left many farms. Eric Heins is doing the reverse: bringing cattle – and their poop, pee and hooves – back to his land. Come see how Eric is using his Normande-shorthorn crosses in a variety of grazing situations. During this Land Stewardship Project-Practical Farmers of Iowa field day, you can view permanent pasture, where Eric (like everyone) is battling the cool-season grass takeover. You’ll also learn how Eric is using his cattle in cover crop mixes, prairie and woodlands.

Since purchasing the farm in 2020, Eric has converted the cropland to pasture. He also custom-farms a diverse rotation of crops, covers and small grains on neighboring farms, including an established prairie on Iowa Department of Natural Resources land. A possible bonus: Eric is hoping to have virtual fence collars by the time of the field day, but no guarantees!

A meal featuring Hoosier Ridge Ranch burgers will follow the field day.

See & Discuss

  • Cash-flowing the conversion to pasture on owned versus rented cropland
  • Stockpiling pasture for winter grazing
  • Mechanical buckthorn clearing for silvopasture
  • Grazing agreements on DNR prairie and neighboring cropland
  • A sudangrass mix after a canning pea crop
  • An extended rotation with oats, barley and Kernza
