Short summary
Microbial-induced calcite precipitation (MICP) is considered an environmentally conscious technology for soil amelioration. We study the response of microbiomes to MICP stimulation in arid soils from different sites and depths. We show that different soil depths host distinct microbiomes, and that biostimulation selects for specific taxa while suppressing others. The study provides evidence for the effectiveness of biostimulation, yet shows that it comes with a cost for biodiversity.
