Summary
This 2025 study explores soil microbial volatile organic compounds as potential non-invasive biomarkers for assessing grassland health across a management intensity gradient. By analysing mVOC profiles, the authors investigate whether microbial scent signatures can serve as rapid, sensitive indicators of soil quality and ecosystem condition in grassland systems. The work suggests that mVOCs may offer a novel monitoring tool for evaluating grassland responses to different land-use practices.
UK applicability
The findings are directly relevant to UK grassland management, given the extensive use of grasslands for pasture-based livestock production and conservation grazing. mVOC profiling could potentially support UK environmental monitoring schemes and agri-environment subsidy assessment, though validation across diverse UK soil types and climatic zones would be needed.
Key measures
Soil microbial volatile organic compounds (mVOCs); grassland land-use gradient; soil microbial community composition; grassland vegetation and management intensity
Outcomes reported
The study evaluated soil microbial volatile organic compounds (mVOCs) as biomarkers of grassland condition and soil health status across different land-use intensities. The research measured mVOC profiles to assess whether microbial scent signatures can differentiate grassland quality and management intensity.
