Ecological stoichiometry has been a showpiece of ecological theory for over 80 years, and the stoichiometric approach used elemental ratios to predict elemental cycling, for example, organic matter decomposition and nutrient retention from microbial cell to ecosystem scales (Allen and Gillooly 2009; Zechmeister-Boltenstern et al. 2015). Most recent stoichiometry studies are limited in aquatic environments. The stoichiometric approach requires considering biogeochemical fluxes along with the terrestrial system. Nutrient availability and its C:N:P stoichiometric ratios are critical in the regulation of nutrient transformation, substrate C (e.g., plant rhizodeposition), and soil organic C (SOC) mineralization in agroecosystems (Zhu et al. 2018; Cui et al. 2020). Agriculture practice has led to a significant increase in anthropogenic inputs of nutrients and C into ecosystems (Ge et al. 2017; Wei et al. 2019). The effects of resource input on soil C dynamics have been interpreted using the theories of “nutrient mining” or “microbial stoichiometry” (Chen et al. 2014). These theories predict that activity, biomass, and composition of microbial communities are driven by microbial demand for resources, like C, energy, and nutrients. Stoichiometry allows a deep understanding of biological mechanisms of elemental cycling at different scales, from cellular metabolism to terrestrial ecosystem (ZechmeisterBoltenstern et al. 2015). However, studies on the relationship of stoichiometry of soil nutrients, plant, and microorganisms with

elemental cycling in terrestrial ecosystems, such as C cycling, are still limited. This special issue aims to bring together a few studies to provide quantitative and mechanistic insights into fundamental processes that govern nutrient and C dynamics, like substrate-derived C decomposition and priming of SOC mineralization, with implications for soil C storage. The cuttingedge techniques, including C isotope, biomarkers, and molecular biology (with high-throughput gene sequencing), have been applied to address the effects of agricultural practices and global environmental changes on soil C dynamics. Five papers have been accepted from 18 submitted manuscripts around the world, though most of th
