Abstract
Tidal fluctuation creates different soil chemical properties which is totally deviate from normal circumstances. Organic matter decomposition occurs with limited O2 supply, hence disturbing Carbon cycle which has a central role in the process and nutrient mineralisation. The research aimed was to describe the relationship between organic-C and available-P due to tidal fluctuation in South Kalimantan. Ten undisturbed composite samples were collected in top-soil and sub-soil. Results showed that there was no direct effect from organic-C in P availability as in other mineral soils. However, there was an indication that the relationship was influenced by maturing process of the soil. In other words, the relationship between organic-C and available-P was typical for every type of swampland and was not related to the tidal fluctuation
