摘要：

Refuse-derived compost (RDC) was produced by mechanical separation of organic matter from domestic refuse followed by a thermophilic composting phase. Fresh (unstable) compost was used in a variety of plant growth trials. Addition of peat, sand or dolomite limestone substantially improved germination. Extended growth trials showed the slow-nutrient releasing properties of RDC. With ryegrass at 6 months growth, identical total yields were obtained with unamended RDC and 150 kg m3 RDC in a sand-grit substrate. Phytotoxicity was confined to the low molecular weight (mol. wt) fraction, while the high mol. wt fraction possessed slight growth-stimulating properties.
