Abstract:
The purpose of this study is to know the spatial variation of the soil in terms of the physical and chemical characteristics and the suitability for the agricultural production. In order to achieve the objective of the study, a space visual scale 50000 : 1, and geological map scale 100000 : 1 and the topographic maps 100000 : 1 were taken to obtain the data from the climate from Al - Kut, Al - Hay, Badra, stations for the period 1982 - 2011.After the termination of the office work, we went to the field for the purpose of observing the area of study and taking samples. 41 sample for the soil were taken, the researcher chooses area samples from different regions of the soil of orchards and the regions of the fodder fields.The study comes up to the following results : 1 - there is a vertical and horizontal characteristics in the soil : textile, structure, colors, real density, porosity, salinity, pH, organic materials, calcium carbon (plaster), calcium sulfate(gypsum).2 - Soil poor with organic materials ranged (%1.5 - 1.74) 3 - the soil suffers from salinity as we went above the Tigris River in the mud. 4 - the value of pH ranged (6.8 - 8.3). The erosion range of soil according to the general equation of the soil losses was assessed. It ranges between (3.6 - 1.5) ton\hectare\year in the shoulders areas while ti ranged between (3.3 - 8.9) ton\hectare\year in the field areas. For the orchard areas, it ranged between (7.1 - 9.9) ton\hectare\year and the bare areas ranged between (3.1 - 16.3) ton\hectare\year. Finally, the classification of the study area by SyS 1980. The lands were classified according to the productivity.
