Özet:

The objective of this study is to develop a land quality index (ACI) based on the area’s original expert opinion and multi-critical decision support approaches and to apply it in agricultural land. The study was carried out in the 7 land series and 43 phases of the Muğla-Dalaman Agricultural Business General Directorate's 3338.61 hectares representing the Mediterranean climate ecology. In the study, a total of 13 indicators with the ability to represent one or more of the land land and land characteristics; i) Land: depth, curvature, stone and drainage; ii) Physical: useful water capacity, volume weight, texture, iii) Chemical: electrical conductivity (EC), pH, organic substance, phosphorus, potassium, total nitrogen and literary knowledge are selected in the light of the expert opinion and literary knowledge. The analytical hierarchical process method, which is a multi-criteria decision support approach, has been used in the bilateral comparison of indicators. According to the study, 61.56% of the operating lands were classified as "very high" and "very high" quality, 35.29% of the land's agricultural quality class was identified as "low" and "very low" quality and maped in the geographical information system environment. The study has found that the quality end index value of the area land has been affected by the depth (% 12.5), curvation (% 12), EC (% 11.1) and bunye (% 10.7) indicators with high weight ratings. It is also recommended that some improvement measures in land with low quality values from agricultural point of view (development of drainage channels, organic additives, stone collection) can be taken to reach high quality classes.
