Registry participants in the United States are currently advised to try Regen Ag Lab(opens in new window) or Ward Laboratories, Inc.(opens in new window) if you need to get your compost tested. Ask for a PLFA test that includes the F:B ratio (fungal:bacterial ratio).

Adventure Unlimited

Contact: Steve Murray

Location:  Buena Vista, Colorado, USA

Number of Johnson-Su Bioreactors:  2

Installation Date: 10/7/2020

Materials used to make BEAM and in what ratio: The usual from the list on this website. Used large fencing staples for attaching cage to pallet. I also used a backhoe to scoop up hay/manure from horse dry feed lot. All material dried. Picked up a half bucket. Filled bucket with bucket facing up and let manure soak, then tipped bucket a little and took material off the top directly into bioreactor. Kept tilting it more to drain whole bucket while I kept filling reactor. Felt like the right moisture content and really easy to load reactor.

Results of finished BEAM (Fungal:Bacterial Ratio): Will know in 9-12 months.
