This review focuses on some important and challenging aspects of soil extracellular enzyme
research. We report on recent discoveries, identify key research needs and highlight the …

The use of fossil fuels and fertilizers has increased the amount of biologically reactive
nitrogen in the atmosphere over the past century. As a consequence, forests in industrialized …

Nitrogen (N) fertilization affects the rate of soil organic carbon (SOC) decomposition by
regulating extracellular enzyme activities (EEA). Extracellular enzymes have not been …

Priming effect (PE) induced by inputs of fresh carbon plays crucial roles in soil organic
matter decomposition and terrestrial carbon cycling. Priming effect is considered to be …

Agricultural and industrial activities have increased atmospheric nitrogen (N) deposition to
ecosystems worldwide. N deposition can stimulate plant growth and soil carbon (C) input …

Variability in the activity and composition of soil microbial communities may have important
implications for the suite of microbially-derived ecosystem functions upon which agricultural …

Ecosystems worldwide are receiving increasing amounts of reactive nitrogen (N) via
anthropogenic activities with the added N having potentially important impacts on …

Biologically essential elements–especially nitrogen (N) and phosphorus (P)–constrain plant
growth and microbial functioning; however, human activities are drastically altering the …

Biota can be described in terms of elemental composition, expressed as an atomic ratio of
carbon: nitrogen: phosphorus (refs). The elemental stoichiometry of microoorganisms is …

Extracellular enzymes mediate the degradation, transformation and mineralization of soil
organic matter. The activity of cellulases, phosphatases and other hydrolases has received …
