- Abstract
The composition and heavy metals content of sludge, solid wastes and coke breeze is detected in the test. Sludge, solid wastes and coke breeze compost the organic composite fertilizer. The experiments on it for rice fertilization were conducted. The results show that the contents of organic matter and N, P, K in wastewater sludge and solid wastes of Guilin are very abundant and heavy metals remain under the criteria. There is a significant efficiency for the organic composite fertilizer applied in raising rice yield, providing an extensive applicability.
