Summary
Published in the Soil Science Society of America Journal, this paper by Calderón and colleagues provides a synthesis of biological indicators used to assess soil health, situating them within the broader context of soil function and management. The authors likely evaluate the strengths and limitations of commonly used biological metrics — including microbial, faunal, and biochemical measures — in terms of their responsiveness to management change and their practicality for routine monitoring. The paper is likely intended to guide researchers and practitioners in selecting appropriate biological indicators for soil health assessment programmes.
UK applicability
While the paper is likely international in scope, its evaluation of biological soil health indicators is directly applicable to UK soil monitoring efforts, including Defra's soil health indicators framework and the adoption of biological measures in agri-environment schemes under the Environmental Land Management (ELM) programme.
Key measures
Microbial biomass carbon and nitrogen; enzyme activity (e.g. β-glucosidase, urease); nematode community indices; earthworm abundance and diversity; potentially PLFA profiles and respiration-based metrics
Outcomes reported
The study likely reviews and evaluates a range of biological soil health indicators — including microbial biomass, enzyme activity, nematode communities, and earthworm populations — assessing their utility, sensitivity, and interpretability as measures of soil condition. It probably examines how these indicators respond to land management practices and their relevance to broader soil health assessment frameworks.
