I built a compost bin and added a single 85% pure salt worm with 96.x salt
I added no other worms just to see what the first humus would look like and I get... 32, 22,22,22 humus with 0% purity.
Why bother grinding up trees at all with results like this.
On the page 13, 14, 15 of this thread I showed some calculation. I can repeat them here as this thread start to be very long.
Impact of bin purity :
(I substract 25 (neutral value to humus and bin)
Humus = 0,2865 * bin
In your example, bin is around 45
Humus = 0,2865 * (45-25) = 5,73
The bin produce an increase of 5,73 on your humus, your humus will have 5,73 + 25 = 30,73 in salt without worm.
Roughly a worm impact is :
Humus = 0,02 * worm (again I substract 25)
In your example, worm has 96 in salt
Humus = 0,02 * (96-25) = 1,42
You combine bin and worm you get 5,73+1,42 = 7,15
So you should get humus near 32,15. (Which seems confirmed by your post)
Of course I don't claim having the exact numbers but you get a quite good idea of what s going on.
One worm is not enough of course. Try to reach 100% efficiency of worm (6 pythons + 1 worm, or 25 worms (but that leave no space for new humus
)), and if you use only worm as good as the one you have, you will reach pretty nice humus value.
