Fig. 2From: Effects of simulated atmospheric nitrogen deposition on the bacterial community structure and diversity of four distinct biocolonization types on stone monuments: a case study of the Leshan Giant Buddha, a world heritage siteSoil physicochemical properties of four biocolonization types under multiple nitrogen addition. A total organic carbon (TOC); B total nitrogen (TN); C total phosphorus (TP); D dissolved organic carbon (DOC); (E), dissolved organic nitrogen (DON); F available phosphorus (AP); G ammonium nitrogen (NH4+-N); H nitrate nitrogen (NO3--N); I pH.
