Although soil bacteria have a key role in ecosystem services and are the most abundant organisms on Earth, the ecological processes and filters regulating their 

distribution at large scale remain poorly understood. Recent studies have clarified the influence of environmental filters on bacterial community diversity and concluded 

that soil pH, texture and C are the main drivers selecting an higher diversity. However, the filters constraining bacterial populations variations remain unclear. In 

consequence, our ability to understand the ecological attributes of soil bacteria and to predict microbial community response to environmental stress is therefore 

limited. 

Based on the framework of the French Soil Quality Moitoring Network (RMQS, Réseau de Mesure de la Qualité des Sols), the objectives were to:

(i)

Identify the bacterial and archael community composition at the scale of French National Territory

(ii)

Determine the spatial patterns of the main phyla at a large scale

(iii)

Rank the ecological processes and environmental filters most influencing the distribution of these phyla.
