The limited landfills cannot accommodate all this waste putting a lot of pressure on the environment. Recycling and reuse of such waste will help to keep healthy environment. The aim of this study was to explore the potential of using some of the components of CW as a soil amendment to improve soil chemical properties and improve plant growth. An experiment was conducted using crushed gypsum, crushed concrete, sawdust and sawdust + gypsum, all collected from a CW treatment plant, and a control. These processed wastes were applied to plots (2x3 m) and mixed with top soil. Fodder barley was sown and irrigated. The treatments were replicated 6 times in a completely randomized design. Results indicated that use of construction and demolition waste such as sawdust and gypsum and crushed sand increased native plant density, plant height and fresh and dry weight of barely fodder compared to control. Maximum fresh weight was found with sawdust and minimum fresh weight was found with control. Organic Matter was significantly affected by the treatments. Maximum organic matter was found with sawdust treatment at 15 cm depth and minimum organic matter was found with gypsum at 30 cm depth. EC was significantly reduced in three sampling dates by the treatments. The reduction was higher in third sample treated with sawdust. The EC was reduced in the order: sawdust > crushed sand > mix (G+S) > Gypsum. Likewise soil pH was significantly reduced by gypsum and increased by crushed concrete treatment. SAR was significantly affected by the treatments in second sample. Maximum SAR was found with control and minimum SAR was found with mix (G+S). Soil water content was also increased with sawdust application and crushed concrete mulching. The study recommended application of gypsum collected from construction waste at the rate of 1.5kg/m2 to saline/ sodic to improve soil EC, pH, reduce sodium hazard and improve barley fodder yield. Also, sawdust can be applied alone or with gypsum improve the chemical properties of soil and improve barley fodder yield. Reuse of some construction waste components can reduce the pressure on landfills, improve soil properties and is an environmentally friendly practice.
