ABSTRACT

The role of peat forest on the paddy fields within the Banjarese Traditional Land Management system was studied in Karya Tani Village, Pulau Petak, South Kalimantan. Filed observation and some laboratory analyses were done in order to understand the soil, including peat layers and water characteristic.

In Banjarese Traditional land Management system peat swamp forest in the upstream were conserved while paddy fields were established in the downstream. Converting the area with potential acid sulphate soils, such as peat swamp forest, into agriculture land by development of canal system would induced pyrite oxidation and cause the soils into extremely acid condition. soils of peat swamp forest may act as water in very high amount; hence the peat swamp forest may act as water reservoir. The water from the peat swamp forest in the upstream may flush out the hazardous substance (produce by pyrite oxidation) in the paddy fields established at down stream.
