Abstract
Peatland fires occur every year in the South Kalimantan Province Indonesia, particularly affecting soil
characteristics. The purposes of this study are to analyze the physical aspects of soil (colour and soil texture)
caused by fires and to investigate the chemical characteristics of soil (pH, Fe2+, P2O5, and K2O). This study used
measurements in the field based on a map of peatland fires in the region and laboratory results. There were 24
samples in this study; they were taken in October 2018, which was about a month after the fire, and in January
2019, which was about four months after the burning. The samples were analyzed regarding the soil colour,
texture, pH, Fe2+, P2O5, and K2O. The results of the study indicated that the characteristics of the soil on burned
land in October 2018 had higher pH, P2O5, and K2O levels than in January 2019. Fires occurred in soil brought
changes to the soil physical and chemical properties. The added combustion ash affected the physical and chemical
properties of the land, such as soil colour, texture, pH, P2O5, K2O, and Fe2+
