Summary
This field-based study investigates the long-term effects of biosolids application on soil microbial communities and their role in nitrogen cycling. By characterising microbial populations and associated biochemical processes over an extended application period, the work elucidates mechanisms linking organic waste inputs to soil biological functioning. The findings contribute to understanding how biosolids-amended soils sustain microbial-mediated nutrient transformations.
UK applicability
The findings are relevant to UK agricultural practice, as biosolids application is a permitted soil amendment under strict regulatory conditions (Environment Agency guidance). However, UK soil types, climates, and management practices may differ from the US study conditions, warranting local validation before informing policy or farm-level recommendations.
Key measures
Soil microbial population size and composition; nitrogen cycling rates and pathways; soil chemical and physical properties
Outcomes reported
The study examined how long-term biosolids application affects soil microbial populations and nitrogen cycling dynamics. Effects and associated factors linked to these soil biological processes were characterised and analysed.
