Neal, A. L., Bacq-Labreuil, A., Zhang, X., Clark, I. M., Coleman, K., Mooney, S. J., Ritz, K., & Crawford, J. W. (2020). Soil as an extended composite phenotype of the microbial metagenome. Scientific Reports, 10(1), 10649. https://doi.org/10.1038/s41598-020-67631-0
 
This paper was a really dense read, but in a nutshell establishes soil as a self-organizing system derived from the interplay of microbial genetics (not just the whole organisms) and soil characteristics, rather than a reducible, mechanical system of many parts. While that may at first glance seem kind of self-evident, here's the peer-reviewed science to back it up.
 
The authors determined that the soil isn't just influenced by microbes; and microbial populations aren't just influenced by soil type, structure, soil organic matter, and so on.
