Abstract
The research objective is to analyze limiting factors of land suitability and efforts to increase tidal lowland capability for paddy in Delta Saleh, South Sumatra, Indonesia. Research sampling was taken intensively in typology types of A, B, C and D. the research was divided into field survey and laboratory work. The research results showed that limiting factors of land suitability for paddy arehigh soil acidity, very low soil fertility, depth of flood water, surface water flow and salinity. The total area of high potential land is 17,982.3 ha (67.4%), around 5,389.4 ha (20.2%) is classified as middle potential land, around 3,308.3 ha (12.4%) belongs to low potential land and less potential land is not found in the field. The soil productivity of the high potential land is 6.0 tons Milled Dry Paddy (MDP) per ha/year, 2-5 tons MDP per ha/year for middle potential land, 1-2 tons MDP per ha/year in low potential land and less than <1 ton MDP per ha/year for less potential land respectively. Efforts to improve to increase tidal lowland capability from actual to potential suitability are as follows : to make drainage channels, to apply the water barrier in order to flow water into cultivated land, to apply agricultural lime, to add and to maintain soil organic materials, to was Na and H cations and to give N, P and K fertilizers.
