Quantifying soil carbon measurement for agricultural soils management: 11 white papers

  • Regardless of what approach is pursued, reliable and cost effective quantification methods are critical to designing and implementing improved management of soil organic matter including soil organic carbon, and C sequestration policies in the land use sector.
Together the group, including Point Blue, produced a set of 11 white papers related to soil organic carbon quantification– see here and below.
• There is heightened interest in increasing soil organic carbon (SOC) stocks to improve
performance of working soils especially under drought or other stressors, to increase
agricultural resilience, fertility and reduce greenhouse gas emissions from agriculture.
• There are many improved management practices that can be and are currently being
applied to cropland and grazing lands to increase SOC.
• Farmers and ranchers are decisionmakers who operate in larger contexts that often
determine or at least bound their agricultural and financial decisions (e.g., crop insurance, input subsidies, etc.). Any effort to value improvements in the performance of agricultural soils through enhanced levels of SOC will require feasible, credible and
creditable assessment of SOC stocks, which are governed by dynamic and complex soil
processes and properties.
• This paper provides expert consensus evaluation of currently accepted methods of
quantifying SOC that could provide the basis for a modern soil information system.
