Abstract: In order to understand the effect of long-term soil es from P fertilizer . It was estimated that
[11]
fertilizer application on accumulation of cadmium (Cd) in Cd in soil from P fertilizer amounted to 660,000 kg . Soil
Typic Purpli-Udic Cambosols and its crop, a research was Cd is difficult to be moved, leached and posed by
carried out by a 15 years’ long-term fix experiment in microbial so that it can be enriched easily in topsoil and do
Chongqing, China. The results showed that Cd great harm to ecological environment and human health, So
accumulated evidently in topsoil of 0-20cm, which content the problem of Cd pollution of long-term fertilization is
[12-15]
was in range of - and exceeded the third concerned and there are many reports about it . However,
