Investigation shows soil habitat quality influences microbial biomass and activity in croplands, suggesting management practices are crucial for agroecosystem functioning.
Key Points
This research analyzes the influence of soil properties and cropping practices on soil microbial communities in Swiss croplands.
Investigated 60 cropland sites in western Switzerland
Considered various soil properties (SOC, texture, pH, SOC:clay ratio)
Examined cropping practices over ten years (tillage intensity, fertilization type/quantity, rotation, cover crops)
Employed a multifactorial approach instead of broad management classification
Soil properties primarily influence microbial habitat and community composition
SOC positively correlates with microbial biomass and activity
Soil pH is key in shaping prokaryotic community composition
Temporary meadow linked to changes in microbial communities
Taxa with similar functions showed varied responses to soil and agronomic factors
