It scientifically justified to conclude that the modelling of cadmium accumulation in agricultural soils in the various assessments suggests the following consistent trends:– For low fertiliser cadmium concentrations (between 1 to 20 mg Cd/kg P2O5), cadmium in soil tends to accumulate relatively slowly, or decreases after 100 years of application due to net removal rates (leaching, crop uptake) exceeding inputs;– For fertiliser with Cd concentrations of 60 mg/kg P2O5 and above, accumulation in agricultural soils over 100 years is relatively high.
