Electronic Theses and Dissertations

This thesis monitored the progression of early-stage humification during the decomposition of four soil amendments and analyzed the effect of hurnification on the copper (Cu) binding capacity of amendment-derived dissolved organic carbon (DOC). Amendments chosen for the 8-week incubation were: wheat straw (Triticum aestivium L.), crimson clover (Trifolium incamaturn L.), a primary papermill residue (PPR), and a primary papermill residue mixed with secondary wastewater treatment sludge (PPR+SS). Specific attention was given to the
