In the natural environment, soil pH has an enormous influence on soil biogeochemical
processes. Soil pH is, therefore, described as the “master soil variable” that influences …

In their natural environment, plants are part of a rich ecosystem including numerous and
diverse microorganisms in the soil. It has been long recognized that some of these microbes …

A wide range of abiotic and biotic stresses adversely affect plant's growth and production.
Under stress, one of the main responses of plants is the modulation of exudates excreted in …

Elemental stoichiometry constitutes an inherent link between biogeochemistry and the
structure and processes within food webs, and thus is at the core of ecosystem functioning …

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 …

Soil enzymes, as indicators of microbial metabolism, play an important role in nutrient
biogeochemistry at the ecosystem level. In this study, we present information from a …

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 …

Microbes in soils and other environments produce extracellular enzymes to depolymerize
and hydrolyze organic macromolecules so that they can be assimilated for energy and …

Although soil microorganisms play a central role in the soil processes that determine nutrient
availability and productivity of forest ecosystems, we are only beginning to understand how …

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