Concentrations of (a) Fe, (b) Mn, (c) Cd and (d) As in the Fe/Mn plaque on the surface of roots of rice. Significant differences are indicated by different letters (P < 0.05). Fe, Mn, and Cd concentrations in the Fe/Mn plaque were measured using the DCB method. CK: control, NPK: all N is supplied by urea, 25PM: 25% of N by pig manure compost and 75% of N by urea, 50PM: 50% of N by pig manure compost and 50% of N by urea, 75PM: 75% of N by pig manure compost and 25% of N by urea, PM: all N is supplied by pig manure compost.
