SMP01 Spatial variation of soil microbial processes under Cornus drummondii shrubs of varying size at Konza Prairie, 2017

Soil was collected from multiple locations under individual Cornus drummondii shrub islands of varying size to measure within-shrub heterogeneity in soil microbial processes. Soil chemistry (Total C, Total N, extractable inorganic N, extractable P, and organic matter cotent), microbial biomass C and N, and potential extracellular enzymatic activity of β-glucosidase, phosphatase, NAG-ase, and LAP-ase were measured. Potential carbon mineralization and the isotopic composition of respired soil carbon was measured over a 77-day laboratory incubation.
