使用四种类型的堆肥（造纸厂污泥堆肥、鱼堆肥、料堆堆肥处理的生物废物堆肥和反应器处理的生物废物堆肥）来评估几个化学参数，作为代替呼吸速率的稳定性指标。分析了堆肥物质、水提取物和NaOH提取物。当所有堆肥一起进行统计处理时，水溶性TOC是唯一与呼吸速率显着相关的参数（r2=0.82，P<0.0001）。建议将其作为堆肥厂的操作参数。本研究中的数据既不支持 [C:N] 比率也不支持腐殖化 [HA:FA] 比率作为稳定性指标。当仅对生物废物堆肥进行统计处理时，TOC（黄腐酸部分）和水溶性氮（总氮和有机氮）是与呼吸速率相关的化学指标。
Four types of compost (paper mill sludge compost, fish compost, biowaste compost from windrow composting treatment and biowaste compost from reactor treatment) were used to evaluate several chemical parameters, which served as stability indices replacing respiration rate. Compost matter, water extracts and NaOH extracts were analyzed. When all composts were statistically treated together, water soluble TOC was the only parameter that correlated significantly with respiration rate (r2=0.82, P<0.0001). This is suggested as an operational parameter at composting plants. Data in this study supported neither the [C:N] ratio nor the humification [HA:FA] ratio as stability indices. When treating only biowaste composts statistically together, TOC (in fulvic acid fraction) and water soluble nitrogen (total and organic) were chemical indices that correlated with respiration rate.
