This study was conducted in Kumkale plain where is sub-basin of Karamenderes flood plain basin. In the study, land evaluation work for rice land use type was carried out where covering (3545 da) area detailed soil survey and mapping work had done previously. In the study a database was created by using GIS techniques. Each rice parcel`s location was detected on the land evaluation map and these parcels` location was determined on the suitability class for (FAO, 1977). An evaluation work carried out with the principles of (FAO, 1977) in the study area (soil texture of topsoil and subsoil, depth, lime content, vertic properties, drainage conditions, surface stony, salinity, organic matter content and pH), topography, geology of region, climate conditions and socio-economic data`s. As the result of study it was determined that 38.89 % of rice lands were S1 (highly suitable), 26.6 % of S3 (marginally suitable) and 34.45 % N1 (currently not suitable). Production which is made not suitable areas cause problems in the study area. This problems can be listed as increasing ground water in rice parcels and their around. Unaccepted water movement to other lands, negative effects in water quality, increasing the production cost, having sociological problems with each other of farmers. In the study area parcels which were permitted have a potential of very big problems for sustainable agriculture.
