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.

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.

8:30 am – 1:30 pm

The Land Stewardship Project is a co-sponsor of the 2023 I-90 & Highway 14 Tour CLASIC. Network, learn, and get inspired with area farmers and regional farming innovators as we discuss current trends for improving productivity and profitability in crop and livestock operations utilizing soil-healthy practices. The Crop, Livestock, and Soil Innovation Conferences (CLASIC) is made up of two tours in Minnesota, traveling along Interstate 90 and Highway 14, consisting of several stops.

Click this link for more details and a complete listing of workshops. Each venue’s program is unique and varied — be sure to check them all out and register for multiple events.

The speaker for the Feb. 6 event will be Dean Sponheim, a fourth-generation farmer from Mitchell County, Iowa. He began strip-tilling in 1999, aerial applying cover crops in the fall of 2012, and started a cover crop seed business in 2014 and no-tilling corn and soybeans in 2019.

Produce Safety Alliance Grower Training Course
Monday February 6
3:30 pm – 5:30 pm

This Northeast Wisconsin Technical College course is for produce growers who want to navigate the best food safety practices for growing vegetable produce. It is for farmers who need to comply with this FSMA (Food Safety Modernization Act) requirement: 

“At least one supervisor or responsible party for your farm must have successfully completed food and safety training at least equivalent to that received under standardized curriculum recognized as adequate by the Food and Drug Administration.”  

Upon completion of the course, you will receive an AFDO/PSA certificate verifying that you fulfilled the requirements of the training. The cost of the certification is covered by Wisconsin Farmers Union.

Martin Larsen farms 700 acres near Byron, Minn., producing corn, soybeans, cover crops and food-grade oats in a full no-till system. As an Olmsted County Soil and Water Conservation District staffer, he gives technical assistance to farmers and manages soil health test plots.

Andy Linder farms with his dad, Don, near Easton, Minn. Together, they raise corn, soybeans, oats, canning crops, and grass hay. Their journey to soil health unintentionally started in 2010 when they purchased a vertical tillage machine. In the fall of 2016, a cover crop was put on every acre and they continue using cover crops. He has transitioned to most corn being no-till.
