- •
Soil nitrogen and carbon as well as bacterial diversity decrease under nitrogen fertilisation without cover crops.
- •
Bacterial community composition is markedly modified under nitrogen fertilisation without cover crops.
- •
Cover crops allow maintaining stable soil nitrogen and carbon concentrations, bacterial diversity, and bacterial community composition.
