Summary
This 2017 field study investigates the mechanistic linkages between atmospheric ammonia deposition and soil microbiological function in oak forest soils. The authors demonstrate that ambient or experimentally elevated ammonia concentrations modulate both enzyme activities and microbial biomass, suggesting ammonia deposition may alter key soil biochemical processes. The work contributes to understanding how atmospheric nitrogen pollution influences belowground ecosystem functioning beyond direct plant uptake.
UK applicability
UK forests and woodlands experience variable atmospheric ammonia deposition, particularly downwind of intensive livestock operations and poultry units. These findings may be relevant to understanding soil health trajectories in UK woodland soils exposed to elevated ammonia, particularly in regions with high livestock density.
Key measures
Soil enzyme activity (as suggested by title), microbial biomass, atmospheric ammonia concentration, microbial community composition
Outcomes reported
The study examined how elevated atmospheric ammonia concentrations alter soil enzyme activities, microbial community composition, and microbial biomass in an oak forest ecosystem. Measurements included quantification of key soil enzymes and assessment of microbial biomass responses to ammonia deposition.
