... Zheyun Zhang,a Jian Gao,a Tami Swenson,b and Yasuo Yoshikuni  a,b INTRODUCTION Soil health is the foundation of civilization and integral to life on the Earth, yet the processes of building or maintaining soil fertility are poorly understood (Amundson et al., 2015)

... Advancing our understanding of the mechanisms by which plant–soil microbiomes control soil chemistry has the potential to identify approaches that build soil organic carbon in marginal soils. This is highly desirable not only because it could decrease atmospheric CO2, but also because it would create an upward cycle of increased biodiversity, and improved water and nutrient retention.

... This is because community-level phenotypes of microbial consortia vary significantly due to the presence of genes, their expression, localization, and population size of microbes in various biogeochemical conditions. Complementing genetic analysis with direct biochemical observations presents an opportunity to establish direct association between genes and functions (Phelan et al., 2012)

... One great advantage of model laboratory ecosystems is the ability to establish causal mechanisms between specific genes; microbes and plants; metabolites; and abiotic factors, for example, to discover biotic and abiotic factors driving soil carbon accumulation. There are several existing approaches that enable discovery and testing of the impact of specific genes on the biochemical ecology of soil microbiomes, which simply are currently not possible to utilize in natural ecosystems.

... be especially powerful in localizing in situ processes within laboratory ecosystems for subsequent investigation using systems biology tools and MSI. Finally, the resulting data and mechanisms would enable development of computational models, including stoichiometric metabolic and functional gene-centric models, for developing soil microbiomes that can then be tested in field studies (see Figure 4-3)
