An Open Strategy to build Soil Carbon part 2

Testing a novel approach to quantify soil Carbon using direct measurements with the Our Sci Reflectometer and soil metadata Previously, we highlighted the potential of soil carbon sequestration to remove significant CO2 from the atmosphere and discussed the challenges in developing pathways for soil carbon sequestration credits. One of the key challenges is the difficulty in […]

An Open Strategy to build Soil Carbon part 1

Why soil Carbon matters Soils are the largest terrestrial pool of organic carbon on the planet, holding as much as 3,000 Gt of carbon in the upper 2 meters of soil. To put that into perspective, the total amount of carbon in the atmosphere is currently about 870 Gt and annual CO2-C emissions from fossil fuels equal about 9.7 […]

We are building a open source reflectometer… and here’s why

“But wait,” you say, “there are already some out there, and they are pretty well designed and reasonably priced!”  Well, yes – there are full spectrometers like the Spectruino ($411), the Open Source Colorometer ($80 + $20 per LED) from IORodeo, and publications from universities describing open colorometer designs (Appropedia and MTU have a good one, but there […]
