摘要：

A comparative study of a bench-scale and a pile composting showed that the C/N, ash percentage and alkaline phosphatase activity were potentially useful parameters for estimating the maturation of cattle manure compost. The values of these parameters were nearly constant during a simulated poor composting, whereas they changed significantly during an optimal process. Other parameters - decomposition degree, chemical oxygen demand, invertase and Rusch number - were less sensitive indicators of composting. The use of these data for agricultural compost samples has shown that high alkaline phosphatase activity and NO//3** minus /NH//4** plus ratio were correlated with compost maturity.
