Soil samples representing the O, A, B, and C soil horizons from soil organic matter (SOM) studies were selected to study the relative effectiveness of 0.1N sodium hydroxide (NaOH) and 0.1M sodium pyrophosphate (NaPyr) in extracting organic carbon (OC). Replicate samples were extracted with each extr...
