Cadmium Accumulation in Soil and Celery from a Long-Term Manure Applied Field Experiment

Abstract:

A field experiment with six treatments was conducted from Apr. 2006 to Nov. 2008 to study the Cadmium (Cd) accumulation in soil and the effect on the plant uptake after a three years application with using different organic fertilizer. The six treatments were (1)Control (with no manure input), (2)Cattle compost, (3)Biogas residua, (4)Chicken compost (with low level input), (5)Chicken compost (with middle level input), (6)Chicken compost (with high level input). The treatments (2), (3) and (5) had the same total N input. The results showed that the soil ETPA-Cd from manured treatments had increased trend compared with the control after 3 years. The celery which was the last crop during the whole cropping history of the manured treatments (except Biogas residua) had higher Cd content compared with the control, and celery of the chicken compost with high level input had highest Cd content than others. There was a significant relationship (r=0.92^**) between the soil Cd content and the celery Cd content. However the soil Cd limitation laws in some countries seem to be strict than the celery Cd limitation law under this soil condition.
