The chemical ecology of soil organic matter molecular constituents
MJ Simpson, AJ Simpson - Journal of Chemical Ecology, 2012 - Springer
Soil organic matter (OM) contains vast stores of carbon, and directly supports microbial,
plant, and animal life by retaining essential nutrients and water in the soil. Soil OM plays …
