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.

Birds on the Farm: Balancing Biodiversity and Food Safety
Tuesday January 13
11:00 am – 12:00 pm
Birds on the Farm: Balancing Biodiversity and Food Safety
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.
