Abstract: 

A laboratory experiment was conducted in sandy soil (%Sand=72.1) planted with wheat (Triticum aestivum L) during 2019, to study the effect of sewage sludge (9 – 18 – 27) g resulting from a treatment plant, irrigating Soil with saline water (4 – 10). – 20) ms\cm on some physical chemical sandy soil properties, content of heavy metals (Cu, Zn, Fe, Mn) and effect on wheat growth. The experiment therefore consisted 12 treatments with three replicates, and plots were completely randomized. An improvement was observed in studied physical soil properties after adding sludge, such as structure soil, water holding, capacity increased, and movement water and air within the soil. Significant increase in organic matter in the soil. Treatment (27g) was superior to other compared to the control. Addition sludge modify pH and increase in the cationic exchange capacity of sandy soil, Its value increased by increasing the rate of sludge use. The study shows a high concentration of heavy metals in the soil while remaining within the normal limits as a result of addition of sludge. The study results showed a significant role of adding sludge in increasing wheat plant growth and dry matter percentage.

Key words: sewage sludge, sandy soil, wheat, heavy metals, saline water.
