Since mid 1950s, over 30% of Lake Idku was dried to create new agricultural lands. The project was extended in 1960s to include areas west of the delta and south of the new/old reclaimed lands. The first study concerning the quality of soil within the study area, south of Lake Idku, was conducted in 1960 and since then, no updates were undertaken to evaluate the effect of the ongoing agricultural/human activities and land use upon the quality of these reclaimed soils. The main objective of this study is to evaluate the change in soil quality in the area relative to the availed analytical data, chemical composition of irrigation water used and crops cultivated during the fall (2010/2011). The impact of different land uses and activities upon the soil quality in the study area, South of Lake Idku, was determined using multivariate analysis (Hierarchal Clustering) in order to identify similarity in patterns and classifying relationships among the measured soil variables.
