Hey all, been talking to @dusjagr and realizing we haven’t been sharing very well some neat stuff we’ve been working on.
Automated Soil Respiration Sensor
@Albercook has been working on automating a process we’ve been using in our lab for measuring soil respiration (a general estimate of soil biological activity). The standard test is the ‘24 hour burst method’ and measures the co2 producing of biology in the soil after it is whetted.
We’re almost to something we’re going to test out in the lab - our goals and specifications were laid out here:
Specifications + Motivation:
I think George it’s time to start documenting a bit more and sharing here, now that we have something interesting looking and prettier pictures Excited to share more and hopeful that this can help democratize and simplify large scale soil sampling…
Would also love ideas about alternative use cases… what else can we measure … nitrogen offgassing? maybe there’s something clever we can do with soil and VOCs + some wet chem process… Anyway, this device is a pretty good general purpose and high throughput device for weigh, generate pore volume, add liquid(s), temp control, measure case (continuous or one time).
