Conclusively, crushed oyster shell could be used as an alternative liming material to restore the soil chemical and microbial properties in upland soil and to increase crop productivity.

High in calcium. I have wondered about its use in the biotub design. Any idea of its availability (as in speed to the plant)? I also wonder how long its total run time is.

They sell it for laying hens. Pretty coarsely ground for our needs, but the acids would break it down. The large grind would not mix thoroughly though.
I ended up using lime. I'm already throwing a lot of variables in my mix.

I have seen powered stuff in boxes for gardening.
