Abstract
Several exploratory visits were conducted in the specific area of the study based on information obtained from the preliminary phase. It carried out a semi-detailed survey of the study area (Magnoon) and by adopting a semi-detailed survey method and relying on topographic maps and natural variation of the plant, by examining the type of tissue, the degree of reaction and the electrical conductivity of the soil through the selection of four Several exploratory visits were conducted in the specific area of the study based on information obtained from the preliminary phase. This variability influenced the B factor values as it ranged from 50 to 100. The first value of the clay class was recorded at pedon P8 compared to the higher values. 100 Recorded for the class of mixed tissue in pedon P4. For the C factor for determining the value of the Earth's regression, it was 1.5% as a general regression of the study area. Factor C is not a determinant of the Earth's suitability for the cultivation wheat of irrigation. For the X factor, 1.5 is while the absence of a specific X factor in the area under study indicates. When classifying land suitability according to the amended Storie index, the two categories (S1) and (S2) were reached, as the appropriate medium class (S2) was observed to prevail over the appropriate high class (S1).
