Re: [compost_tea] Re: micron vs. mesh - again
The largest beneficial nematodes are about 25 micrometers in width, but about
150 in length.
Fungal fuzzies can get up to 100 micrometers as well, so you want opening
sizes around 200 micrometers.
But working with Bruce Elliott, we've seen limitations in getting organisms
through the 200 micrometer openings. The openings get plugged with fine
organic matter, so we've aimed for slightly higher opening sizes. In the 300
to 400 micrometer size range. You could just buy Bruce's compost tea bag.
It has been tested for optimal organisms movement through it, and works well
in his brewers.
So, somewhere between 200 and 400 micrometers opening sizes, depending on
your compost.
Hope this helps!
