On the basis of areas with complex topography and soil diversity is proposed a stepwise model for reclamation of lands for planting of vineyards. The model includes climate, soil and hydromeliorative conditions. Limiting components are presented as being localized in different parts of the area limitations of the suitability. The strength of the constraints is evaluated depending on the area of their occurrence, the extent to which they limit the suitability of the terrain and the opportunities for ameliorative correction. Soil sampling and mapping of soil is performed by applying of GIS for characterization of the spatial diversity. Obtained results are analyzed based on the expectations for constraints and non-differentiability of the function characterizing the properties of the soil at each point within the field. Through this approach is considered the minimum number of points required for investigation and are localized the areas for correction of limitations arising from the properties of the soil and terrain.
