6/15:
Started processing these soils at about 1815 today -- rather late for samples taken about 1100, so might be a bit too dry.
Dry weights taken 21 hours later.
Comparison sensor measurements read by eye from WWW plot.
6/21: 1200
In both cases, should have driven the corer further in (collar was flush, but apparently had compacted) -- use 0-2cm in both cases. a.soil also still had some litter and b.soil had some roots.
