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.

Minnesota Women in Conservation: Conservation Land Walk in Dawson

During this Minnesota Women in Conservation event, participants will walk around a “homestead” farm site — exploring areas and goals the landowner hopes to improve in the future, including pollinator habitat, perennial plantings, wind breaks, privacy/noise screens, water quality improvements, well sealing, and compost placements. Participants will hear feedback and recommendations from a conservation professional on potential programs that could assist the landowner in achieving those goals. 
 
This is a FREE event, but you must RSVP here to get the address. For more information and to RSVP, click here.
