Abstract
To assess the effects of long-term fertilization on arsenic (As) accumulation in soils and crops with different agricultural practices, five experimental stations (Changshu, Taoyuan, Hailun, Fengqiu, and Qiyang) with long-term fertilization practices, representing five typical soils of China, were selected to investigate the soil As concentrations. Results indicated that the geological source, that is, parent materials, played a dominant role in determining the soil As concentrations. Long-term application of manure and phosphorus fertilizers led to a decrease of As concentration in the surface paddy soil at Taoyuan, while the effects of fertilization on As concentration in other samples wer..
