Degradation of soil is including of every loss of soil yielding power or loss of soil nutrients needed plant by erosion. In this study, for investigating soil quality degradation and map preparation, were selected the Honam sub-basin with 140 km 2 , located in the south of Alashtar in the Lorestan province in Iran. This sub-basin is one of the most important regions of production in agriculture and animal husbandry unit, and it is one of the critical sub-basins in the Karkheh River basin. Using of interpretation of ETM+ satellite images (Photomorphic units) the area of study was divided in homogeneous units of soil degradation and was known as a working unit. Per working unit, soil samples were prepared and were determined the properties of organic carbon, total nitrogen, phosphorus and available potassium, bulk density and micronut...
