This research was carried out with the aim of identifying the basic efficiency characteristics of the Central and Eastern Black Sea Area agricultural land and creating land distribution maps using geographical information systems. In the framework of the research, a total of 3400 land samples were taken from 0-20 cm of land depth with 2.5 x 2.5 km grid intervals to represent agricultural areas. In the samples of the land taken, the analysis of the cranberries, pH, electrical conductivity, cranberries, organic substances, capable phosphorus and extracted potassium has been done. The results of the soil analysis, classified according to certain criteria, determined the levels of nutrients deficiency, sufficiency or excess. After the classification of land parameters, a database was created within the framework of Geographic Information Systems and land efficiency maps were produced. According to the study, the majority of the Middle and Eastern Black Sea region’s agricultural land are thin (middle-in-house) land (75.30%) according to the overall grouping of land, with pH values very variable (< 4.5-8.5). A large majority of the land was found to be medium-good-high level, saltless and 61.15% of the land was less purple. In 58.83 percent of the territory there is phosphorus deficiency, while in 42.68 percent of the territory there is sufficient potassium that can be extracted.
