    Abstract

    There are about 95.812 ha of critical to potential critical 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 dan chemical properties are needed in order to find out how these land are suitable for low land rice growth. 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 dan chemical properties are structure, texture, permeability, organic matter content, pH, N-total, P and K. Drainage and slope steepness are also investigated in the field. Then soil suitability for low land rice are classified based on laboratories data dan field data. The results show that soil pH, drainage, soil texture, pirite, and tickness of peat are as limiting factors for paddy plant. Actual land suitabilities are S2 and S3 Classes, if the drainage system was rehabilitated and lime was applied for increasing pH, the potential suitable classes become S1, S2, and S3. Only texture could not be improved, but to minimize texture effect it could be applied organic matter. However, dominantly land in this area are potentially suitable for development and extension of paddy field and might be one of the biggest land recourse for supporting South Sumatra as food producer .
