Abstract: Abstract Microbial activity and functioning in soils are strongly limited by carbon (C) availability, of which a great proportion is released by living roots. Rhizodeposition and especially root exudates stimulate microbial activity and growth, and… read more here.

Abstract: Abstract Decomposition of soil organic matter (SOM) is operated by microbial extracellular enzymes and is dependent on temperature. It remains unclear how input of labile organics interacts with temperature on SOM decomposition. Soil samples collected… read more here.

DOI: 10.1371/journal.pone.0202086
Abstract: Although microorganisms will preferentially allocate resources to synthesis of nitrogen (N)-acquiring enzymes when soil N availability is low according to the resource allocation model for extracellular enzyme synthesis, a robust link between microbial N-acquiring enzyme… read more here.
