The Chemical Properties of Burnt Peat Soil in Teluk Bakung Village, West Kalimantan

Peatland is one of Indonesia's unique ecosystems and has various functions in maintaining environmental stability. The increasing demand for land in various sectors has led to activities in peat areas. Land conversion and sub-optimal management of peatland can affect the properties of the peat. This study aims to analyze the chemical properties of peat soil on four land management areas in Teluk Bakung Village, West Kalimantan. The areas were rubber stand, burnt land, taro plantation with non-burning land management, and taro plantation with burnt land management. The method used was purposive sampling with a set of five points as soil sampling within the plot measuring 20 m x 100 m. Soil samples were taken at a depth of 0 – 10 cm at each site. Then, the soil samples were evenly composited for further analysis in the laboratory. The results of the study showed that the parameters of the chemical properties at each site had various values. Burnt land had higher N, P, K, Na, and CEC values. Meanwhile, the highest pH, Ca, and Mg values were in taro plantations with non-burning land management. Then, the highest ash content values were in taro plantation with burnt land management. For the value of C-organic, rubber stand had the highest percentage compared to the other land conditions.
