Abstract

The descriptive analytical study of the Rawa Pening peat soils characteristic has been done. This study was purposed to determine the potential of peat soils as a microbial carrier. The parameters observed were chemical properties (pH, levels of C, N, P, K and CEC) and biological properties (total of soil microbial population), and its amendments by air drying, ovens drying and sterilization process with autoclave (temperature of 121o C, pressure 1.5 atm for 15 minutes).  The results showed that Rawa Pening peat soil has the content of high organic C, medium-high N, low-medium P, high K and high CEC. Total of soil microbial population is quite high, and reduced by air drying and autoclave sterilization. The population of soil microbe has pressured with oven drying, but the process makes it a low pH which was caused by the cell lysis.  The Rawa Pening peat soils has physical properties that are not easily changed, is also not prone to changes in pH during the process by air drying and sterilization with autoclave. The Rawa Pening peat soils have a potential to be a microbial carrier, because it has high organic matter content, and easy at processing.
