Table 2.

Integration values for all NMR peaks when orthophosphate was set to 1.00.

Soil type	Plot	Monoesters	Diesters	Pyro-phosphate	Poly-phosphate	Phosphonates	PtotalNMR	Orthophosphate/total
Brunisol	Sooke	0.82	0.19	0.16	0.15	ND	2.32	0.43
Brunisol	Niagara	1.03	0.28	0.17	0.22	ND	2.70	0.37
Upland Podzol	Fairy Lake	0.61	0.42	0.16	0.24	0.07	2.50	0.40
Upland Podzol	WC 1000	0.65	0.48	0.14	0.23	0.08	2.58	0.39
Lowland Podzol	Branch 136	1.30	0.48	0.18	0.19	0.32	3.47	0.29
Lowland Podzol	Branch 247-63	1.45	0.51	0.18	0.20	0.28	3.62	0.28

The values are proportional to P concentration. P_total^NMR is the sum of all integration values except the internal standard.

ND not detected.
