Our machine learning models are designed to provide reliable and scalable estimates of soil organic carbon (SOC) by combining georeferenced field measurements with multi-source satellite and geospatial data. Model performance is evaluated using independent validation datasets to assess predictive accuracy, robustness, and spatial consistency across agricultural landscapes.
Rather than relying exclusively on sparse physical sampling, our approach integrates continuous earth observation data with AI-driven calibration workflows to generate statistically validated SOC predictions at scale. Performance metrics such as R², RMSE, MAE, and regression slope are used to quantify model quality and evaluate the agreement between predicted and observed SOC values.
The validation example presented here features results from an agricultural field located in Ontario, Canada, where predicted SOC values derived from satellite and geospatial data are compared against observed field measurements. The fitted regression demonstrates a strong correlation between AI-predicted and ground-truth SOC observations, while also illustrating the natural variability typically encountered in environmental and agronomic datasets.
In practice, model performance can vary depending on factors such as climate conditions, soil composition, crop systems, sampling density, and the availability of regional calibration datasets. For this reason, uncertainty quantification and independent validation procedures remain central components of our modeling framework. As additional soil measurements and earth observation datasets become available, the models can be progressively refined to improve predictive stability, regional adaptability, and large-scale transferability.
