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
