All samples are properly weighed, air dried, and sent to an outside lab for SOM or %C testing. SACRA generally recommends the %C dry combustion testing (vs. SOM) in order to estimate carbon stocks.
The soil carbon level of each sample is then correlated to the initial satellite data layers used to determine the sampling locations. Layers are examined and compared to soil carbon data to use the strongest correlations to estimate soil carbon across the area of study.
The methods used in the soil carbon quantification study are derived from highly credited scientific literature and are accepted by most carbon registries.
Of the services SACRA offers, Soil Carbon Quantifications fluctuate the most in price/hectare given the different sampling densities needed for different landscape types.
Scientific Credibility
At SACRA, we base our methodologies on rigorous, peer-reviewed scientific research to ensure the highest standard of accuracy and reliability. Our team integrates data collection with cutting-edge techniques, drawing from established studies to validate our approach in environmental monitoring, land assessment, and carbon capture analysis.
Our methods align with industry standards and contribute to the growing body of knowledge in fields like agroforestry, remote sensing, and carbon sequestration. Below is a selection of the key scientific papers and references that underpin our work:
