| Abstract | ||||
| THE GOVERNMENTAL plan aims for reclamation and cultivation of about 400,000 feddans concentrated mainly in El-Tina Plain (50,000 feddans), South East El-Qantara (75,000 feddans), Rabaa (70,000 feddans), Bir El-Abd (70,000 feddans) and El-Ser and El-Qawarir (135,000 feddans) areas.. The present study revealed that there is no much variation in soil fertility status of soils developed on various landforms in the studied area as the soils have low to medium organic carbon (0.14 to 1.20 %), low available nitrogen (4.19 to 46.70 mg/kg); low to high available P (4.11 to 59.23 mg/kg) and deficient to adequate available K (34.00 to -825 mg/kg) contents. The soils of South East El-Qantara were categorized according to nutrient index into medium-low-medium-low (MLML) category based on OC, available N, available P and available K concentrations, respectively. | ||||
