Water Management Practices Affect Arsenic and Cadmium Accumulation in Rice Grains

Table 1

Physico-chemical properties of soils used for the pot and field experiments.

Parameter	Pot experiment	Field experiment	Ave. S.E.*
pH	5.8	5.0	0.08
Organic C (g kg^−1)	13.9	17.7	0.96
Total N (g kg^−1)	1.39	1.75	0.035
Olsen P (mg kg^−1)	4.8	30.4	1.08
Available K (mg kg^−1)	75	81	2.8
Arsenic (mg kg^−1)	9.47	4.29	0.215
Cadmium (mg kg^−1)	0.10	0.12	0.003

*Ave. S.E. is the mean of standard error (SE) of soil parameters in pot and field experiments.
