Testing simple soil carbon measuring tools (journal)
Simple, yet reliable models are needed to quantify soil organic carbon (SOC) changes for a wide diversity of agricultural management conditions. This article compares the outputs of two relatively simple models currently available for farmers and government-financed farm support agencies: the Carbon Management Evaluation Tool for Voluntary Reporting of Greenhouse Gases (COMET-VR) and the Soil Conditioning Index (SCI). Our results suggest that both models have value and limitations and that measures of SOC sequestration are predictable with these tools under a diversity of typical management conditions.
