Process-based models and quality-controlled datasets that quantify how management decisions affect soil health, yields, and the environment.
Process-based models that reveal how ecosystems function and respond to management practices, applied from research to industry.
Daily Century Model
Simulates daily carbon and nitrogen fluxes across plant and soil systems, connecting ecosystem processes with management outcomes.
Microbial Efficiency-Matrix Stabilization Model
Simulates daily soil carbon formation and decomposition with measurable carbon fractions across flexible, continuous depth intervals.
Download the model executables for local workflows, or use the LandEngine Model Runner API for web-based runs without local installation and configuration.

High-quality datasets for ecosystem and soil carbon science, each with metadata, citations, and download access for consortium members.
Beyond our own data products, we have compiled more than 30 external databases and repositories spanning soil, carbon, and environmental science. From global soil profile archives to flux networks and national observatories, these resources are gathered in one place to help you find the data that supports your work.
