Soil productivity of El-Monofeya, Governorate Central Delta,( located between the two branches of Rosetta and Damietta -between longitudes 30° 10' & 30° 40' E and latitudes 31° 5' and 31° 25' N,) was done. The area is 254303.01 ha. There were eight major mapping units: overflow basin (OB), decantation basin (DB), high river terrace (RT1), moderate river terrace (RT2), low river terrace (RT3), turtle back (TB), hummocky area (HA), and sand sheet (SS).Requier Land productivity index (RLPI) was done based on the parametric approach and Remote Sensing/GIS techniques.RLPI was used taking into account soil properties and topographic parameters using specific formulas. Of the total area, 54.51 % (106631.58 ha) are excellent and good classes (class I and class II) for agricultural use, 0.91% (2323.38 ha) belong to the ‘average class’ (class III), 12.77% (32472.00 ha) are ‘poor class’ (class IV). The remaining of the area 20.09 % (51168.53 ha) are ‘extremely poor class’ (class V) due to inefficient management practices. |
