Abstract

Forest and land are a natural resource that have an important role in maintaining the balance of the ecosystem. However, forest and land fires occur almost every year in South Sumatra in particular in the area of Ogan Ilir. The fires have dire consequences for the balance of the ecosystem and the quality of the soil that can be utilized for agricultural land and plantations. This study aims to determine the changes and comparison of some physical properties of soil on fire and non burned on various of vegetation in dry land. The physical properties of the soil include: water content, bulk density, total pore space, permeability,texture, structure and color of the soil. This study was conducted in North Indralaya Ogan Ilir. The method used was a case study in 3 vegetation, namely: forests, rubber and scrub with the conditions of each vegetation was burned and unburned. This research was conducted in October-December 2015 and the data obtained is a secondary data (interviews) and primary data (observation and analysis). Soil sampling to a depth of 0-25 cm using plot system. The main plot size is 2 m x 2 m in the main plot, there are 3 sub plot with a size of 20 cm x 20 cm. This study suggests that, fires a very significant influence on vegetation rubber. This is indicated by the changes of the condition of water content of 32.37% to 19.23%, the value of soil bulk density of 0.6 g/cm³ to 0.9 g/cm³, the value of total pore space from 77.23% to 65, 92% and permeability of 23.94cm/hour to 19.84 cm/hour. Soil texture on all the vegetation changes from sandy loam to loamy sand, structural changes occur on the granular into sub angluar blocky. And then, the soil color changed from dark brown to black and dark. Significant changes in the physical properties of rubber vegetation due to morphological rubber containing latex is high, so the intensity of fires is higher. Increased soil temperatures caused by fire, damage the soil pore spaces and burning ashes resulting dark black soil.
