21堆肥源分离的家庭生物废物加上其他有机材料进行了评估，其生物成熟度。样品的大部分被证明是成熟的，并在水芹的植物生长测定中增强植物发育。除标准理化参数外，还测定了水溶性C/N、腐殖酸/富里酸比值、400 nm和600 nm处的吸光度比值（E4）和阳离子交换量（E6）。这些参数都与植物生长无关。因此，无论是作为一个指标来预测生物成熟度的生长促进和缺乏植物毒性。用堆肥提取物进行的发芽试验的结果与植物生长试验的结果有很好的相关性。堆肥对腐霉立枯病有抑制作用。抑制效果的强弱与堆肥中有机质含量有关。
Twenty-one composts from source separated household biowaste plus other organic materials were evaluated for their biomaturity. The major part of the samples proved to be mature and enhancing plant development in a plant growth assay with cress. In addition to the standard physical and chemical parameters, water soluble C/N, humic/fulvic acid ratio, ratio of optical absorbances at 400 nm (E4) and 600 nm (E6) and cation exchange capacity were determined. None of these parameters was correlated with plant growth. Thus neither was suitable as an indicator to predict biomaturity in terms of growth enhancement and lack of phytotoxicity. The results of a germination test with compost extract were well correlated with the results of the plant growth test. Composts were suppressive to Pythium damping-off. The extent of suppressiveness was connected with the composts' content of organic matter.
