الملخص الإنجليزي

The study aims to build a model to clarify the spatial variation of the fertility levels of the soil of Sayed Ahmed Al-Rifai, and to achieve this, (10) soil samples were collected and sent to the laboratory of the Ministry of Science and Technology in Baghdad Governorate for physical and chemical analyzes, as the coordinates of those samples were determined using a device (GPS) To be projected on the map of the study area in order to produce spatial variation maps for it by relying on spatial analysis methods in the GIS program (GIS) Using the spatial modeling tool (Geostatatic Wizard) Then activate the feature (Interpolation) Or synthesis of spatial characteristics of the samples and analysis of spatial variation of those characteristics to be classified soils study area by levels Al_khasobah, as the study reviewed a number of classifications down to the classification more accurately to get the spatial disparities of fertility levels in the soils study area through the application of the equation (NAI) As varied Soils hand Sayed Ahmed Rifai, according to levels Al_khasobah between the level (low and medium) as it occupied the average level of the largest area, which amounted to about 675 km 2 and by (85% ) of the study area either level (low) is the least space and proportion as it reached about 118 km 2 and (15% ) of the soils study area The results showed that soils in the study area suffer from low content of potassium and available phosphorous elements.

Therefore, it is recommended to develop appropriate organic and mineral fertilizer programs to provide these two elements in particular to increase their fertility.
