The objectives of this study were to assess the land capability using Storie Index and Cervatana model and to assess the land suitability by LUSET and Almagra model for some coastal soils in Egypt. Twenty-seven soil profiles were dug and morphologically described to represent all physiographic units. Landsat image, DEM, geological map, field and laboratory work were used to create physiographic-soil map relationship. Based on the modified Storie Index, soils were classified into four land capability grades (grade 2, 3, 4 and 5). The Cervatana model classified these soils into three capability classes, S2, S3 and N. Almagra model indicated that 4.71 % of the area is highly suitable (S2) for wheat and citrus and 14.82 % of the area is S2 for olives. About 31.78 % of the soils is moderately suitable (S3) for wheat and citrus where-as 52 % are S3 for olives. Based on LUST, about 5.85, 3.73 and 2.11 % of soils are highly suitable (S1) for wheat, cotton and olives respectively. About 31 % of the area is moderately suitable (S2) for citrus and peach where-as 63.86 % is S2 for alfalfa and 85 % of the area is S2 for wheat. Soil salinity, calcium carbonate, drainage and soil texture were the most common limiting factors of the soils. The study revealed that the MicroLEIS application either Cervatana or Almagra is not suited to predict the land suitability and land capability while the LUSET and Modified Storie index is recommended for Egyptian pedoenvironment.

The area under investigation bounded by 25° 16-26° 7-E and latitudes, 29° 7-29° 21-N; and extended for about 70km in east-west direction, with a width of 7-10 km. The dominant texture class varied from sand, loamy sand, sandy loam; and silt loam. pH values ranged between 7.4 and 9.3. CaCo3 content ranged between 1.6 and 42.3%. O M values varied from 0.1 and 2.6%. Gypsum content ranged between 0.01and 5.04%. EC values varied from 0.5 and 98.3 (ds/m). The CEC values varied from 1.9 and 35.09(mq/l). ESP values varied from 6.3 and 36.4%. Nitrogen values varied from 11.1 and 55.9(ppm). Phosphorus values varied from 2.8 and 60.8(ppm). Potassium values varied from 186.6 and 933.1 (ppm). Based on the american soil taxonomy the soils were classified as Typic Torripsamments,

Most forms of land degradation are human resource (mismanagement and misuse); some physical and chemical environmental factors are still considered. Quantitative assessment of land degradation and monitoring the changes in land qualities in Wadi El-Natrun are the main objective of this study. Physiographic map of the area was produced by using ETM+, ENVI 5.0 and ArcGIS10. Physiographic map used to determine soil profiles location and soil samples. From the physical and chemical analysis the results compared with the data extracted from Mohamed, (2011). Land degradation rate, relative extent, degree, and severity level in the study area were assessed. The results indicate that the dominant active land degradation features are; water logging, salinity, alkalinity and compaction. Based on the FAO/UNEP, (1979) program of degradation (rate, relative extent, degree, and severity) and the application on that data of water logged, salinity, alkalinity and compaction compared with Mohamed, (2011). The results indicate that the following:there is no effect of compaction so there is no compaction degradation. Waterlogged degradation as water table depth changed from 2011 to 2013 as following (50-100 cm) the degraded area increased from (234.32 to 341.28 km 2) , (100-150 cm) the soil improved and the degraded area decreased (from 356.31 to 218.42 km 2) and (> 150 cm) were improved. Salinity degradation as electrical conductivity(EC dS/m) data changed from (2011 to 2013) that the (8-16 dS/m) the degraded area increased from (0.0 to 16.83 km 2), (4-8 dS/m) the soil improved and the degraded area decreased (from 190.86 to 110.43 km 2) and (<4 dS/m) the soil improved and the area increased (from 399.76 to 451.87). Alkalinity degradation data changed from (2011 to 2013) that the (>15 %) no change , (10-15%) the soil improved and the degraded area decreased (from 437.98 to 190.82 km 2) and (<10 %) the soil improved and the area increased (152.64 to 388.32 km 2
