The concentration and potential ecological risk of Mn, Zn, Cu, and Cd in the surface soils (0-30cm) belonging to 12 soil profiles and 4 soil types (Vertisols, Chernozems, Calcisols, and Cambisols) from the cultivated soils and the corresponding uncultivated soils were investigated. Long-term cultivation caused a considerable build-up diethylene-triamine pentaacetic acid (DTPA)-extractable Mn (7-55%), and Cd (12-31%) as well as the total form of Zn (3-14%), Cu (8-25%), and Cd (33-78%) in all soil types. Following long-time cropping, total Zn (mean=73mgkg(-1)), Cu (mean=33mgkg(-1)), and Cd (mean=3.14mgkg(-1)) and DTPA Zn (mean=1.2mgkg(-1)) and Cu (mean=2.44mgkg(-1)) were below their maximum allowable limits. However, the average amount of DTPA Cd in the tilled soils (min=0.4, max=0.75, mean=0.55mgkg(-1)) was above its maximum permissible limit mainly due to the over application of phosphate fertilisers and the pesticides. Considering the potential ecological risk (RI) assessment of the cultivated soils (min=44, max=70, mean=54), the soil types were categorised as low (RI <= 50) to moderate (50
