In the study, digital soil maps produced by the Abolished General Directorate of Rural Services in Turkey were used. Geographical Information Systems (GIS) (Arc GIS 10.3.1) software was used for the spatial evaluation of soil data in the study. According to the spatial analysis results; Dry marginal agricultural areas with 2857.7 km 2 constitute a large part of the current land use of Kırşehir Province. This area covers 44% of the total. When the large soil groups of Kırşehir province are examined, brown soils constitute a large part of the region. It has been determined that brown soils correspond to 2710.4 km 2 area and 41% of the existing area. The soil depth structure has been observed to be generally medium depth soils. Medium deep soils have an area of 2052.1 km 2 and constitute 31% of the total area. As for the soil slope class, it was seen that a large part of the region was between the 2nd degree slope group (7-12%) and the 3rd degree slope group (13-20%). When the soil erosion degree was examined, it was seen that a large part of the region had 2nd degree erosion. Soils with 2nd degree erosion group constitute an area of 2294.3 km 2 (35%). Sharing the digital land use data obtained in the study will provide significant contributions to the investor organizations that will invest in the region and contribute to agricultural production.

In addition, most of the animals feed on land and human life takes place on the land. The population in the world shows a rapid increase. This increase also increases the need for food consumption. Most of the nutrients in the world are provided by agricultural activities. With the increasing population, industrial activities also show development and increase. In this increase, the raw material of many industrial establishments depends on the soil together with agricultural production. The characteristic structure of the soil in agricultural production is of great importance in terms of production. The properties of the soils vary according to their location. Determining all the characteristics of existing soils in order to identify and solve problems, management techniques applied from the beginning to the end of the production should serve the sustainable and efficient use of soils (Tunçay and Bayramin, 2010).
