Abstract
"Soil organic matter (SOM) influences nutrient cycling, water retention, and biological activity, which is a cornerstone of soil health. Total soil organic carbon (SOC) constitutes about 58% of SOM. Total SOC is an important long-term measure of soil quality, but it changes slowly and may not reflect the impact of recent changes in crop management. Permanganate oxidizable carbon (POXC}, also referred to as reactive carbon, is a widely used indicator for assessing the reactive fraction of total SOC, which is the portion of carbon most readily available for microbial metabolism and nutrient cycling (Weil et al., 2003; Culman et al., 2013). Typically, POXC accounts for 1-4% of total SOC (Culman et al., 2012; Hurisso et al., 2016)." -- first page
