| Abstract | ||
| Soil spatial variation is very valuable in deciding the suitable cropping system and appropriate agricultural management of lands. This research paper was done to measure the spatial variation of some soil characteristics, in the western farm of Faculty of Agriculture, Cairo University, Giza province, Egypt. Soils of studied area were classified as Typic Torrifluvents. 100 samples of soil were gathered at depth of 35 cm during 2016. Sampling designee was done by a grid systematic sampling system, using GPS. Samples of soil were gathered at spacing of 30*30 m2. Some soil characteristics including EC, pH, CaCO3, Organic matter (OM), Particle density (Pd), Bulk density (Bd) and Porosity (P) were determined in laboratory. Descriptive statistical analyze were achieved to describe soil properties. Geostatistical procedures of semivariograms and krigingcoupled with a GIS were utilized to interpret the variability ad mapping of spatial distribution of soil characteristics. The coefficient of variation displayed that the chemical properties the soil were more fickle than the physical properties. Electrical conductivity was the most variable characteristic. Results explained that EC and pH had the maximum and the minimum spatial correlation respectively. | ||
