Physical and Chemical Analysis of Land in Forest Peat Swamp in Resort Pondok soar, Tanjung Puting National Park, Central Kalimantan

Abstract

Abstract Peatlands are ecosystems with the particular characteristic that is high organic matter content. On the other hand, these features lead to the peat soil vulnerable to decreasing the quality of the land. This study aimed to analyze the physical and chemical properties of peat soil in the peat swamp forest in the Resort Pondok soar, Tanjung Puting National Park in Central Kalimantan. The method used in this research is systematic sampling with a set of five points as soil sampling with twice replications within the plot measuring 100 m × 100 m. Peat soil at the site of research has added to peat ranged from 20 -> 400 cm. Tests showed there are different levels of maturity of peat from fibric until saprik, and the peat is likely to have the same maturity level or more raw than the maturity level of peat with field tests. The results of color identification are very dusky red, dark reddish-brown, reddish-black, and black. Peat soil has a pH ranging from 3.7-5.2 with an average pH of 4.5 (acidic), does not contain pyrite, ash around 1:13% - 43.88%, and the content of organic C ranges from 32.55% - 57.35%.
