Effects of different artificial topsoils on some ornamental plants

This project was designed to study the effects of different artificial topsoils produced from mixing incinerator flyash, sewage sludge, biochips and subsoil (from granite origin)on the physiology of some local popular ornamental plants. These artificial topsoils contained various levels of heavy met...
