Summary
This century-long field study examines how sustained fertilisation alters the predictability of grassland soil microbial community assembly. The authors report that persistent nutrient enrichment appears to reduce stochastic (random) processes in community succession, potentially leading to more deterministic assembly pathways. The findings suggest that long-term agricultural nutrient management has profound effects on fundamental soil ecosystem processes and microbial diversity dynamics.
UK applicability
Directly applicable; the work was conducted at a United Kingdom grassland research site (likely the Park Grass Experiment at Rothamsted). The findings are relevant to UK grassland management and fertilisation policy, particularly for understanding how conventional nutrient inputs shape soil microbiome stability and resilience over decadal timescales.
Key measures
Microbial community structure (likely 16S rRNA gene sequencing or similar), stochasticity indices, assembly process metrics (deterministic vs stochastic contributions), temporal succession patterns over fertilisation treatments
Outcomes reported
The study measured soil microbial community composition and succession patterns under century-long continuous fertilisation treatments in grassland. It quantified changes in stochasticity and determinism in microbial assembly processes as a function of nutrient enrichment history.
