NMSU SASC

Contact: Amy Larsen(opens in new window)

Location: Alcalde, NM, USA

Number of Johnson-Su Bioreactors: 6

Installation Date: March through June 2018

Materials used to make BEAM and in what ratio: Measurements are in % by volume. Recipe 1: 83% brown (wood chips, brown leaves); 17% green (dairy/chicken manure, food waste, alfalfa hay). Recipe 2: 40% brown (wood chips, brown leaves, straw); 60% green (horse/chicken manure, barley grain, alfalfa hay)

Results of finished BEAM (Fungal:Bacterial Ratio): From PLFA analyses on finished compost. Recipe 1: (0.3697); Recipe 2: TBD June 2019.

Sept. 30, 2020: NMSU SASC completed microbial testing on four bioreactors currently in progress. The ages of the bioreactors vary:
B1/B2 tested at 30.5 months; B5/B6 tested at 26.5 months; B7/B8 tested at 15 months; and B9/B10 tested at 14.5 months. In discussing the results with the Lab Director, he suspects that B1/B2 may have become anaerobic, causing the protozoa numbers to dip below the desired range and the ciliate numbers to be high. Otherwise, he said, the results from the other bioreactors look good. See test results for B1/B2 (PDF), for B5/B6 (PDF), for B7/B8 (PDF), and for B9/B10 (PDF). PLFA Results for July 2020: B1-B8 (PDF) and B9&B10 (PDF).

Installation Date: Sept. 8, 2019

Materials used to make BEAM and in what ratio: approximately 1/3 Leaves, 1/3 Hay containing legumes, 1/3 woody material

Results of finished BEAM (Fungal:Bacterial Ratio):

I found a new lab certified by Elaine Ingham in Germany - called Erdbaum - where one of my Johnson-Su bioreactor composts was tested. (Lab report (opens in new window)KP1)(opens in new window)

As a comparison I also tested some usual garden leaf compost. (Lab report KP2(opens in new window)). To my surprise it even had a little higher fungal to bacterial ratio.

Overall, it is aerobic compost, but there were signs of anaerobic conditions in both composts.

Maybe the bioreactor has gotten too much rain and was overwatered with watering one minute a day, so it seems to need less water than in an arid climate as in New Mexico or California. An exception might be in the summertime and other long periods of low relative humidity and lots of wind. Overall, a protection from rain and might be useful.
