Utilization of land resources that slope and shallow solum need to get attention, so that agricultural business can be profitable and sustainable. The more intensive the land use for agriculture, the slope of land is currently experiencing quite heavy pressure, in addition to the uncertain climate conditions and changes. On the one hand there are demands of some communities for agricultural land to produce maximally and on the other side there are also demands for land slope used wisely and sustainably, while the ability and condition of society in the utilization of the land is quite diverse. This is a matter of concern, because it will increase the area of land for the successful development of agriculture. Thus a study is needed to model the specific dominant land aspects of the site in the development of a crop species on a sloping and shallow solum agricultural area. This research is aimed at: (1) to formulate productivity model of shallow slopes and solum in corn cultivation area in Timbuseng Village, Pattallassang District, Gowa regency of South Sulawesi; (2) Determine or map potential sites or areas for corn plant development based on existing climatic conditions in the research area. This research was conducted in Gowa District, South Sulawesi Province. Location determination is done deliberately, because this area is generally sloped, has a shallow solum and climatic conditions are changing. Soil sampling is done on each profile that has been made, and there are 32 points of observation that is divided into 17 units of land, then conducted a laboratory analysis to determine the physical, chemical and biological properties of the soil. The land productivity model was established on the basis of relevant land characteristics and influenced the production of maize, the range of each land characteristic determined by regression analysis. Analysis of the relationship between land characteristics with corn production using correlation analysis. The results showed that the potential area for the development of maize in Timbuseng Village, Pattallassang District, Gowa regency of South Sulawesi, is located on 01, 05 and 14, with corn yields rather high (above 6 tons per hectare).
