Microbial Respiration
Benchmark Value
Scoring Curve
This curve shows how a field measurement for this indicator would score across all available benchmark forms in this context.
Evidence & Context
a provisional target range for basal or substrate-induced microbial respiration... for the topsoil (e.g., 0-10 cm) of Australian alpine/subalpine pastures in high environmental health under best-practice sustainable/regenerative grazing might be in the order of 20 to 150 mg C kg⁻¹ soil d⁻¹.
basal or substrate-induced microbial respiration (measured under standardized laboratory conditions, e.g., 20-25°C, optimal moisture, after a pre-incubation period to minimize rewetting flush effects)
This benchmark represents a provisional target range for microbial respiration in the topsoil of Australian alpine and subalpine grasslands under sustainable grazing practices, indicating healthy microbial activity.
Synthesized from available data including Australian sub-alpine lab incubation data and international alpine field data, adjusted for standardized laboratory conditions.
