| Abstract | ||
| North Sinai gained the priority over the other part of Sinai due its strategic location and promising output. The effect of chemical. physical and geological properties of some units of North Sinai soils is studied for future agricultural practices consideration. Twenty eight profiles have been selected covering the study area of 2830 km2 in North Sinai. The soil samples were collected from each profile representing geomorphological and lithological changes.Coarse textured soils are characterized by the predominance of sand over clay and silt. Looseness, friability and good coarse textured soils represent more than 90% of the studied area, while fine textured soils occupy a triangle area in the northwestern ~art. Most of the northern part has been found free from salt affected soils « 4dS m' ), while most of the southern part have salt affected soils (> 4dS m"). The pH of the studied area ranged from 6.2 to 9.0. Due to the low rate of rainfall and limited degree of leaching in the region, calcium carbonate is a common constituent of SOils. Organic matter content of the studied soils ranged from 0.3% to 22.6%. The total N content Is not adequate for plant growth. The minimum level of P is considered to be the adequate level for plant growth. Potassium content is ranged from adequate to very high level for plant growth. The surface irrigation water of EI Salam Canal is suitable for the growth of non sensitive plants, while drainage and subsoil water are not suitable for irrigation. Ground water is suitable for irrigation of non sensitive plants to salinity. A complete and integrated scientific strategy is required to reduce salinity of soil. Also, maintain acceptable range of nutrients for plant growth is required to build a long-term plan for maximum utilization of North Sinai soils. | ||
