This work presents the safety of municipal solid waste (MSW) compost produced by

Kashy Company, and its effects on some soil chemical properties and plant growth. In

order to investigate the effects of Kashy Compost on soil properties and growth of chard

plant, pot experiment was carried out in an optimum growth condition. This experiment

was carried out under greenhouse condition at the Faculty of Agriculture, University of

Duhok, using three different treatments consisting of control soil, MSW levels selected

for this study were (0) control, (%5W/W) MSW, (%10W/W) MSW, and (%15W/W)

MSW. The results obtained in this experiment indicate that application of municipal

solid waste improves the plant growth. It was also found that application of municipal

solid waste had significantly increased soil pH and EC. The results showed that

application of MSW in different rates improved plant growth. Shoots dry and fresh

weight were found at a maximum when 5% MSW was applied. Application of MSW

gave an increased concentration of heavy metals in plant, especially in 15% MSW

treatment.
