The most important factor in controlling the partitioning of a metal to soil is the solution pH; heavy metal adsorption is governed by soil characteristics such as pH and organic matter content (Evans, 1989). Often, Chemical composition of soil organic carbon (SOC) is central to soil fertility. We hypothesize that change in SOC content resulting from various long-term fertilization strategies accompanies the shift in SOC chemical structure.
