| Abstract | ||||
| A survey study was carried out on soil chemical characteristics and nutrients content of crops at Sahl El-Tina (North Sinai), irrigated with El-Salam canal water. Soil samples were collected from 0-60 cm depth from ten sites. Soil pH values varied from 7.40 to 8.01, EC of soil ranged from 1.93 to 7.28 dS/m. Dominant soluble cation was Na+ followed by Ca++ then Mg++ and K+ . Dominant soluble anion was Cl- followed by SO4- - then HCO3- , no CO3— was found in the last order. Ranges of soil available nutrients (mg/kg) were 6.84 to 66.82 for N, 1.73 to 3.75 for P, 135.5 to 164.00 for K, 1.01 to 14.41 for Fe, 0.05 to 2.99 for Mn, 0.03 to 1.61 for Zn and 0.98 to 5.29 for Cu. Ranges for N P K in plant (%) are 2.79 to 5.11 for N, 0.33 to 0.55 for P, and 1.87 to 4.92 for K. Ranges for Fe, Mn, Zn, Cu in plant (mg/kg) 37.83 to 75.24 (Fe), 25.14 to 50.79 (Mn), 37.00 to 57.79 (Zn). Cu was within the toxic level in all the tested crops, ranged from 36.57 to 78.25. | ||||
