CFSA on Farm Intensive

Organic Management Strategies and Soil Health

These are images for the Compost portion of the on farm intensive session I’m teaching for the 2024 CFSA Sustainable Agriculture Conference. My focus is on the building and use of the Johnson-Su Bioreactors for producing fungal dominant compost which is great for making extracts that can be easily sprayed to boost the microbiology of your soil.

The original approach:

Pallet with holes to allow air flow.
PVC held in place with wire on top, screws on bottom.  Removed after 2 days, leaving an air tunnel.  System irrigation automated, 1 minute every day.

Modified Johnson-Su setup using barrels, reduces watering needs, easier to unload and transport.

Barrels with 1/2 inch hole drilled every six inches.
Detail of screws to center PVC pipe on the bottom while loading.
Bioreactors on a pallet for easy transport

A great air injector system for static piles.

The key to an efficient static pile, active aerated setup.  The bubbler pump runs for 5 minutes, every 30 minutes. 1/2" pex with 1/16" holes drilled every inch.

Aeration tube on the bottom of the pile.  Easier to remove with a tractor bucket than large PVC.
