Inoculating Biochar after pyrolysis with microorganisms and or nutrients is recommended by almost every expert that you will study. This is because biochar has a high CEC, (Cation Exchange Capacity). A substance that has a high CEC with no cations adsorbed to it will soak up the first cations that it comes in contact with. If freshly pyrolysized biochar is placed directly in a substrate or soil it will rob the surroundings of it’s cation nutrients, leaving the soil and or substrate with less available to the plants.  I wanted to know just how much biofermentation and or water a certain amount of Biochar absorbed when inoculated.

So let me give you the results here at the top of the post

Results:

500ml of biochar absorbed 276 ml of water (55.2% by volume)

or

106gr of biochar absorbed 276 gr of water (260.4% by weight)

Here is how I got to these figures:

 

I started out by filling a 500ml glass jar with biochar and weighed only the biochar.

.

I then filled a 500ml plastic cup with 500ml of water and poured it in the glass jar with the biochar. The glass jar held the biochar and an extra 406ml of water. The extra 94ml of water was left in the cup.

.

I let the BC with water in the glass jar sit for 24 hrs and then drained the water from the jar.

.

Of the 406ml poured into the jar with the biochar, 130 was drained out after 24 hrs. Therefore there was 276ml of water absorbed by the biochar sample.

.

Results:

500ml of biochar absorbed 276 ml of water (55.2% by volume)

or

106gr of biochar absorbed 276 gr of water (260.4% by weight)
