Adsorption is an important geochemical process that removes dissolved organic carbon (DOC) from water percolating through soils, which eventually flows into groundwater and the river channel (where it is respired to CO2). Soil properties, such as texture, Fe- and Al-oxide content, and soil organic carbon content, are known to affect the concentration of DOC in soils (and, therefore, the quantity of DOC transported to river channels) and vary widely with soil type. We collected soil cores from various depths to use in continuous, unsaturated flow soil column adsorption experiments and for analysis of soil properties. We examined relationships between adsorption and a suite of soil properties in an attempt to estimated the quantity of DOC adsorbed based on soil type. Quantifying the DOC lost to adsorption as a function of soil properties is an important step in understanding the export of carbon fixed on land and transported to rivers.
