The optimum pH and Eh for simultaneously minimizing bioavailable cadmium and arsenic contents in soils under the organic fertilizer application

[Display omitted] •Soil pH and Eh have a significant effect on the speciation of Cd and As.•With increasing pH or decreasing Eh, bioavailable Cd content linearly decreased.•With increasing pH or decreasing Eh, bioavailable As content exponentially increased.•The optimum trade-off of the bioavailable...
