Abstract
There are about 95.812 ha of critical to potential land and about 2.665.829 ha of potential land in Ogan komering Ilir regency, these land have not been cultivated for agriculture. Identification of soil/land physical and chemical properties are needed in order to find out how these land are suitable for low land rice. Low land rice is choosen because this area are flooded in rainy seasson and dried in dry seasson, that why traditionally farmers cultivate their soils are based on water level (sonor or padi lebak). Data analysis of soil physical and chemical properties are structure, texture, permeability, organic matter content, pH, N-total, P and K. Drainage and slope steepnesss are also investigated in the field. Then soil suitability for low land rice is classified based on laboraties data and fild data. The result showed that soil pH, drainage, soil texture, pirit and tickness of peat are as limiting factors for paddy plant. Actual land suitabilities are S2 and S3 classes, if the drainage system was rehabiliated and lime was applied for increasing pH, the potential suitable classes become S1, S2 and S3. Only texture could not be improved, but to minimized texture effect it could be applied organic matter. However, land in this area are potentially suitable for development and extention od paddy field and might be one of teh biggest land resource for supporting South Sumatra as food producer.
