Tea luggage with rock mud
Each pot had a small tea bag with 5 gram of the amended rock mud buried within the soil. By preserving these luggage we are able to now have a look at the rock grains, analyze adjustments in grain dimension distribution or BET floor space or discover out if some “coating” has occured which may gradual weathering.
Soil samples!
In the end, getting our arms on soil samples, was a very powerful a part of the dismantling course of. We couldn’t take soil samples earlier through the 24 months experiment as a result of taking e.g. 100 g out of a 12-15 kg pot by poking a gap into it might have probably modified the hydrology and as such the weathering processes.
We homogenized the soils (manually!) for various vertical layers and now these samples are despatched to a number of labs across the planet for evaluation. We’re REALLY wanting ahead to discovering out what these soil analyses will inform us in regards to the weathering, this knowledge will complement the intensive leachate water knowledge, biomass knowledge and fuel knowledge that we have now already collected.
