Abstract
Barambai reclamation unit in Barito Kuala regency, South Kalimantan, has great potential for tidal swampland agricultural development. Therefore, agricultural land suitability information is required. Evaluation of Barambai agricultural land suitability is conducted using Quantum GIS (Geographic Information System) software on land unit categories data (pyrites, cation exchange capacity, ash content value, salinity, hydrotopographic zone, and drainability). Identification and analysis results indicated that soil fertility is low to moderate, the pH of the soil is acid to very acid, and relatively high pyrite hazards. Agricultural land suitability in Barambai tidal swampland reclamation unit is most suitable for paddy plant (S1 and S2 criteria).
Highlights
Tidal swampland in Indonesia, especially South Kalimantan province has the great agricultural potential
Barito Kuala regency in South Kalimantan province consists of tidal swamp area 96.07% (287,992 hectares), while the 3.93% (11,774 hectares) is inland swamp [1]
Soil samples were collected from five locations (Fig. 1) located in Barambai reclamation unit in South Kalimantan province
Summary
Tidal swampland in Indonesia, especially South Kalimantan province has the great agricultural potential. Evaluation of land suitability for agricultural optimation in Barambai reclamation unit is using Geographic Information System (GIS) tools. The advantages of this tools are easy for data updating, data coordinates can be addressed clearly, and can be overlaid with other spatial themes. Utilization of GIS technology is expected to acquire detailed information about existing conditions, water management zone, and tidal swampland agricultural suitability. This information is expected to be used for appropriate land management recommendations
