Chemical characteristics of soils collected prior the experiment at 0–20 cm layer under uninoculated trees and trees to inoculate.

Treatments	pHH2O	NH4+ + NO3-	Org. C	Sol. P
Uninoculated trees	5.3 ± 0.34a	09.1 ± 2.45a	0.23 ± 0.02a	29.8 ± 3.31a
Trees to inoculate	5.8 ± 0.20a	12.8 ± 1.14a	0.25 ± 0.01a	27.3 ± 2.04a

Values within a column sharing same letter are not significantly different at P < 0.05 (Student–Newman–Keuls test).

NH₄⁺ + NO₃^- (mg/kg of soil); Org. C, organic carbon (%); Sol. P, soluble phosphorus (mg/kg of soil).
