| Abstract: | In a pot experiment,the sewage sludge from Xiamen Yundang Wastewater Treatment Plant was applied as organic fertilizer to study its effects on the growth and yield of pakchois and the transfer and accumulation of heavy metals in pakchois-soil system. The sludge was rich in nitrogen,phosphorus,potassium and organic matter,and its heavy metals contents were lower than the limits of national control standard for the pollutants in sludge for agricultural use. Appropriate application of the sludge could promote ... |
