Introduction

As the name implies, soil biogeochemistry is a scientific field examining the complex and inseparable interactions between the biotic (living) and abiotic (non-living) components of soils. Soils are not studied in isolation but are instead viewed as a key nexus in the exchange of matter and energy between the atmosphere, aquatic and marine systems, and the subsurface. The chemical, physical, and biological complexity of soils necessitates our understanding of soil processes relies on the advancement of analytical technology. In the 21st century, insights from genomic studies and high-resolution chemistry analytical tools have overturned long-standing paradigms about soil formation and revealed novel decomposition and stabilization pathways.

General Overviews

While the field of soil biogeochemistry has only been formally organized for a few decades (Gorham 1991), its origins are evident in the writings of luminaries that recognized the importance of interactions between the abiotic and biotic components of soils. For example, the seminal work of Jenny 1941 articulated how the interactions of climate, geology, and biology drive the formation of soil organic matter. These fundamental insights were the foundation for more recent advances in our detailed understanding of soil formation, summarized by Lehmann and Kleber 2015. Other aspects of soil nutrient cycling have been elucidated, and new aspects continue to be discovered to the present (van Groenigen, et al. 2015). Even as we continue advancing our understanding of soil biogeochemical processes, humans continue altering them, making this work as relevant and important as ever (Paul 2014).
