RhizoWheat – Enzyme kinetics

Wheat monoculture may affect root morphology and wheat rhizosphere traits. Thus, these changes in roots could have impacts on the plant nutrient uptake, microorganism activity, and surrounding soil properties. Hence, pre-cropping affects microbial energy resources (e.g. root exudate), thus, indirectly changing microbial activity, growth strategies; efficiency of metabolism (reflected in enzymatic activity (Vmax) and its efficiency, catalytic efficiency (Ka), substrate turnover time (Tt)). This, in turn, indirectly affects the mobilization of organic C and N. Here we presented the results for activity and kinetics of enzymes – as a tool to reflect microbiome functionality – involved in C and N cycles measured in soil samples collected from two field locations (Harste, Göttingen; Hohenschulen, Kiel) in 2020.
