Abstract Microbial carbon use efficiency (CUE) affects the fate and storage of carbon in terrestrial ecosystems, but its global importance remains uncertain. Accurately modeling and predicting CUE on a global scale is challenging due to inconsistenci

Decomposition kinetics are fundamental for quantifying carbon and nutrient cycling in terrestrial and aquatic ecosystems. Several theories have been proposed to construct process-based kinetics laws, but most of these theories do not consider that mi

Microorganisms function as open systems that exchange matter and energy with their surrounding environment. Even though mass (carbon and nutrients) and energy exchanges are tightly linked, there is a lack of integrated approaches that combine these f

Microbial decomposers face large stoichiometric imbalances when feeding on nutrient-poor plant residues. To meet the challenges of nutrient limitation, microorganisms might: (i) allocate less carbon (C) to growth vs. respiration or excretion (i.e., f

A better understanding of the litter decay process is critical for improved predictions of terrestrial carbon (C) exchange between above and below-ground C reservoirs. Furthermore, developing well-constrained decomposition models with explicit repres

Microbial explicit models are constructed by linking decomposition (the process of organic matter break-down) and substrate uptake to microbial growth, respiration, and mortality. Therefore, the specific choice of the decomposition and/or uptake kine

Microbial pesticide degraders are heterogeneously distributed in soil. Their spatial aggregation at the millimeter scale reduces the frequency of degrader-pesticide encounter and can introduce transport limitations to pesticide degradation. We simula

The role of root physiological and structural plasticity for carbon allocation in plant-soil systems

Plant roots are essential for acquiring water and nutrients from soils and constitute a major input source for soil organic matter. Plants invest a significant proportion of the photosynthetically fixed carbon into the growth and maintenance of their

The growth and maintenance of the plant root system may consume more than 50% of all photosynthates, making the root system a major carbon sink (Lambers et al., 2002). Carbon is supplied to roots via sieve tubes that are located in the phloem of the

Knowledge of functional traits such as the maximum substrate uptake rate and growth efficiency of microorganisms is crucial in understanding the turnover and storage of soil organic carbon. In addition to CO2 measurements, heat dissipation from organ
