Long description:
The science of soil breathing, at home
Soil gives off CO₂ as microbes break down organic matter, and that flow tracks how alive the soil is. I measured soil CO₂ flux in field research. This guide turns that science into home methods anyone can run, with the same care for fair comparison a lab would use.
What you will learn
Why temperature and moisture change the result, and how to control for them
How to run a soil respiration test at home with a CO₂ burst kit
Four other methods, from earthworm counts to the tea bag test
How to set up repeats and a reference spot, so your results mean something
Inside: step-by-step methods, USDA NRCS scoring scales, and seven fillable data logs.
