The area of peat swamp forest is decreasing over time due to natural disasters and man-made. To restore its original condition, forest restoration efforts need to be made. One of the keys to the success of peat swamp forest restoration is the characterization of the condition of the peat to determine the appropriate restoration technique. Apart from its vegetation aspect, peat swamp forest restoration can also consider the use of biological agents to fertilize the land so that forest restoration can take place more quickly. The study was conducted to describe the condition of the peat and recommend biological agents to fertilize peatlands in the Katingan Peat Swamp Forest, Central Kalimantan. This study used a secondary dataset of Katingan Peat Swamp Forest 2015 published by the Center for International Forestry Research (CIFOR). Data were collected in July and October 2015 on two plots located on the north and south sides of the study area. The main plot is 100 x 100 m2 divided into 25 sub-plots measuring 20 x 20 m2. Peat sampling is carried out on the ground along the 5 cm center point of depth systematically. This study conducted an assessment of the depth of peat organic matter, bulk density, C-organic content, total N-content, and C / N ratio. The results of the analysis in the Katingan Peat Swamp Forest were compared with peat conditions in other locations where the ecosystem was still intact, namely the Sebangau Peat Swamp Forest. Based on the results of the analysis, in general the condition of the peat in the Katingan Peat Swamp Forest was classified as good based on the depth of the peat organic matter 371.1 cm (very deep), the content weight of 0.12 g / cm3 (quite good), the content of C-organic 46, 62%, the total N-content is 1.27%, and the C / N ratio of 39.131% is classified as 'Very High'. The condition of the peat in the Katingan Peat Swamp Forest is no different from that in the Sebangau Peat Swamp Forest. Biological agents that are predicted to be able to adapt and fertilize peatlands are arbuscular mycorrhizal fungi (AMF) from the genus Glomus and Acaulospora.
