Soil carbon and water: correcting a figure the sector repeats
A 0.1% soil carbon gain does not hold 200,000 litres per hectare. The soil-mass arithmetic, the measured figure, and what soil carbon really buffers.
Soil sampling design: how many samples do you actually need?
Sample count follows from your confidence level and minimum detectable difference - not from a fixed ratio. What stratification changes, and what it cannot.
What soil carbon MRV actually costs - and what cannot get cheaper
Verification usually takes 25–50% of a soil carbon project's budget. Across 8,845 ha of ESA pilots, stratified sampling brought it to 4.1% of credit revenue.
Where soil carbon credit revenue actually comes from
Practice is spreading faster than proof. Sequestration uncertainty bands, reversibility, and why permanence provisions matter more than a single measurement.
