A concept to optimize the accuracy of soil surface area and SOC stock quantification in mountainous landscapes

A correct quantification of soil surface and soil organic carbon (SOC) stocks is crucial for the evaluation of important soil functions, including atmospheric C sequestration. At present, soil science lacks (i) a clear definition of soil depth, (ii) consented procedures for soil sampling, as well as (iii) adequate awareness concerning pitfalls and caveats associated with quantification of soil surface area and large-scale SOC stocks in...
