Abstract

Soil pollution with heavy metals is a great concern as this considerably affects plant both quantity and quality and consequently animal and human health. Detection of the spatial distribution of heavy metals provides good source of information for appropriate soil remediation procedures. Geostatistics and its different interpolators are of great importance for revealing the spatial distribution of any soil variable. The aim of this work is to delineate the spatial distribution of cadmium content insoil irrigated with polluted drainage water of Bahr El-Baqardrain. A total of 100 soil samples were collected over a field of 4.6 ha located in Bahr El-Baqar area, Sharkia Governorate, Egypt. Ordinary kriging was applied as an interpolator for cadmium content interpolation. Prediction assessment was performed using cross-validation calculating two different statistics; mean error (ME) and mean squared standardized error (MSSE). Results showed that the model is unbiased and accurate since ME and MSSE values were of -0.004 and 1.17 respectively. Three management zones were obtained based on cadmium content named as zone 1, zone 2 and zone 3and their range values were0.500 – 1.140, 1.141 – 1.676 and 1.677 – 2.125, respectively. The delineated zones indicate that the field has different multiplicative degrees of cadmium pollution regarding agricultural land use. It is recommendedthat such polluted soils must be appropriately remediatedbefore agricultural land use. It is also recommended that the irrigation water source that comes from Bahr El-Baqardrain should be substituted with a good unpolluted irrigation source.
