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.

11:00 am – 12:00 pm
Birds in the Balance: Pest Control Services Across Crop Types
Tuesday November 4
11:00 am – 12:00 pm
Birds in the Balance: Pest Control Services Across Crop Types
Online

This 10-lesson Wild Farm Alliance virtual course teaches agricultural professionals and farmers how to support beneficial birds and manage pest birds on farms. By learning how to assess the farm’s avian needs and opportunities, farms can be designed to provide for a diversity of beneficial birds. 

If pest birds are a problem, they can be discouraged with specific practices during the shorter periods when they cause damage. The sessions cover the latest research, tools and resources, and are given by experts in avian pest control, entomology, ornithology and conservation. While many topics and species are specific to the Midwest, most of the principles discussed are applicable across regions. 

Continuing Education Credits have been requested and are expected to be approved from American Society of Agronomy.

Big Ag, Big Problems: LSP Panel on Rural Consolidation
Lanesboro Community Center, 202 Parkway Ave S, Lanesboro, MN 55949, USA

 
The concentration of money and power in our food and farming system is a threat to our rural way of life, the land, and Main Street economies. According to research compiled by Farm Action, agricultural industries ranging from poultry processing to seed distribution are now dominated by four or fewer corporations, creating a system that for all intents and purposes no longer represents an open market situation. This makes it next to impossible for small and mid-sized farms to compete economically.  

Those of us who grew up in the rural Midwest have seen these effects firsthand. As once vibrant agricultural economies diminish, so too do community resources: hospitals, public schools, religious institutions, grocery stores, and more. Young people who see little opportunity in their hometowns move to cities and suburbs to start their careers and families. 
 
A consolidated, corporate-controlled agricultural system is also wreaking havoc on our natural environment. Runoff from large-scale factory farms and row cropping operations threatens our drinking water and spoils natural landscapes that people from all walks of life cherish. Without intervention, it won’t be long before all of us — urban or rural, farmers and non-farmers, rich or poor, young or old — will be impacted by the devastation of Big Ag. 

Join the Land Stewardship Project on Tuesday, Nov. 4, to hear from two people who think a lot about the power of Big Ag and its negative impacts — Austin Frerick and Sonja Trom Eayrs. They will lead a discussion about the forces threatening our rural communities and how we build the people power to take them on. 

This is an opportunity to take the first steps toward developing the kind of positive future for our communities that builds homegrown wealth, treats people fairly, and is resilient in the long term. If you love something and someone, you fight for it. Come fight with us! 
 
Austin Frerick Biography: Austin Frerick is an expert on agricultural and antitrust policy. In 2024, he published his debut book, Barons: Money, Power, and the Corruption of America’s Food Industry.
 
Sonja Trom Eayrs Biography: Sonja Trom Eayrs, author of Dodge County, Incorporated: Big Ag and the Undoing of Rural America, is a farmer’s daughter, rural advocate, and attorney.
