Summary

This 2017 field study investigated the relationship between ambient atmospheric ammonia deposition and soil biological functioning in an oak forest. The research suggests that elevated ammonia concentrations modulate soil enzyme activities and microbial biomass, with potential implications for soil health and nutrient cycling in forest ecosystems. The findings contribute to understanding how air pollution affects belowground microbial processes.

UK applicability

Relevant to UK woodlands and agroforestry systems exposed to atmospheric nitrogen deposition, particularly in regions downwind of intensive livestock operations. UK soils similarly experience elevated ammonia from agricultural sources, making findings potentially applicable to assessment of soil health impacts from air pollution.

Key measures

Soil enzyme activity, soil microbial biomass, microbial community composition, atmospheric ammonia concentration

Outcomes reported

The study examined how elevated atmospheric ammonia concentrations affect soil enzyme activity, microbial community composition, and microbial biomass in an oak forest soil system. Measurements included soil enzyme activities and microbial biomass as indicators of soil biological health and function.
