Research Project: Microbial Communities in a Long-Term Agro-Ecosystem Research (LTAR) Aspirational Grazing System

Location: Grassland Soil and Water Research Laboratory

Project Number: 3098-11000-001-66-S
Project Type: Non-Assistance Cooperative Agreement

Start Date: Sep 1, 2019
End Date: Sep 30, 2021

Objective:
Quantify how soil microbial communities vary with temperature change and determine the mechanisms underlying thermal acclimation of microbial respiration, in typical grassland soils under contrasting BAU and ASP grazing management practices in at the Texas Gulf Coast LTAR site.

Approach:
Quantify microbial substrate, microbial activity, community composition, and physiological adaptation in the two management practices. Microbial substrate features to be examined include SOC quantity and quality. Microbial activity features to be examined include microbial biomass, extracellular enzyme activities, and microbial respiration.
