摘要

The aim of this study was to determine the suitability of municipal solid waste (MSW) compost as a source of organic matter in a medium for container plant cultivation and field production. In two experiments, conducted at the Agricultural University of Wroclaw in 1994-1995, the suitability of MSW compost at various stages of maturity was tested. In a pot experiment, fresh or 1, 3 and 9 months old compost was used at 0, 100 or 400 t ha~(-1). In a field study the suitability of a twelve month old compost applied at rates of 30, 60 and 120 t ha~(-1)was determined with butterhead lettuce as a forecrop, and white head cabbage as the main crop. Nine month old MSW compost was a valuable component of the medium for plant cultivation while the less mature composts reduced plant stands and final yield of lettuce. In field production only 120 t ha~(-1) was a sufficient source of N for growth and yield of cabbage. For lettuce this fertilization resulted in a lower yield then where nitrogen fertilization at the rate of 70 kg N ha~(-1) was used. The contents of Pb, Cd, Ni and Cr in edible parts of both species supplied with MSW compost were similar to the unfertilized treatment.
