Hayes et al. (2008) described the uses of 0.1 M sodium pyrophosphate (Pyro) solutions for exhaustive extractions of soil organic matter at pH 7, pH 10.6, and at pH 12.6 (Pyro + 0.1 M NaOH). They showed that the fractions were compositionally different, with the most transformed (oxidized) fractions isolated at the lower pH value. However, only about 26% of the organic matter was isolated in the sequential process.

In addition to being the enzymatic agents of biotic decomposition of SOM, microbial cell by-products are increasingly recognized as major building blocks of SOM. As a result, the microbial community, controlled by climate, vegetation, and soil environment, is a key mediator of organic matter composition and decomposition. The spatial scales of influence, however, have not been well characterized.
