Does structure really matter? Exploring implications of microbe-structure interactions to carbon dynamics at the field scale Open
Soil structure determines crucial soil physical processes, such as water distribution, gas flow, and cycling of carbon and nutrients. This way, it builds and constrains biological habitats. The resulting environmental conditions at the mic…
