Table 1. Distance-based multivariate multiple regression showing relationships between environmental variables and bacterial community structure.

Variable (mg kg-1 unless otherwise listed)	P	Prop. (%)
Mineral N	0.001	28.4
HCl-extractable P	0.001	51.8
Plant Biomass (g)	0.008	58.8
Microbial Biomass C	0.01	67.4
Colwell P	0.03	72.6
NaHCO3-extractable P	0.06	76.6
Resin-P	0.1	82.0
NaOH-extractable P	NS	-
Residual P	NS	-

Data shown are from a forward-selection model where only variables that contributed significantly to the model were included. The significance of the relationship (P) and the cumulative percentage of variation explained (Prop.) is shown.
