Fig. 2: Soil parameters reflecting water retention, carbon cycling, nitrogen cycling, and phosphorus cycling in soils derived from Ca-rich and Ca-poor parent materials.
From: Calcium-rich parent materials enhance multiple soil functions and bacterial network complexity
a Soil water retention indicated by water holding capacity (WHC). Carbon (C) cycling parameters: soil organic carbon (SOC, b), microbial biomass carbon (MBC, c), dissolved organic carbon (DOC, d), α-glucosidase (AG, e), β-D-glucosidase (BG, f), β-xylosidase (BX, g), and β-D-cellobiosidase (CBH, h). Nitrogen (N) cycling parameters: total nitrogen (TN, i), total inorganic nitrogen (TIN, j), β-N-acetyl-glucosaminidase (NAG, k), and leucine amino peptidase (LAP, l). Phosphorus (P) cycling parameters: total phosphorus (TP, m) and acid or alkaline phosphorus (AP, n). Bars represent means ± standard errors (n = 21). Different lowercase letters represent significant differences at p < 0.05 between Ca-poor and Ca-rich parent materials.
