Abstract
The objective of this work is to assess the soil degradation status around Edku lake and know the effect of the lake on this area. So, soil samples were collected from different dimensions and directions from Edku lake, and physical and chemical properties of the collected soil were determined. Soil degradation was assessed based on the methodology developed by the Food and Agriculture Organization. The results of soil samples analysis showed that the total salts value in soil extract ranges between 1.44 ds /m and 21.63 dS/m, with an average of 7.14 dS/m. the study area is divided into four categories of salinity levels according to the FAO guide, they are low in salinity, medium salinity, high salinity, and very high salinity and it represents 58.33%, 12.50%, 8.33% and 20.83%, respectively of the study area. The results of soil chemical degradation index showed that 17% of the study area was soil of medium chemical degradation, and 29% of the study area was soil of high chemical degradation, while 54% of the study area was soil of very high chemical degradation. Also soil biological degradation index illustrates that 58% of the study area was soil of medium biological degradation, and 42% of the study area was soil of high biological degradation.
