| dc.description.abstract | Kampar Peninsula is one of the peat areas that has a high conservation value in Riau. Most of this areas have been converted into agriculture, plantations, and industrial plantation forests. This activity will reduce the amount of vegetation and affect microbial community composition and activity, which in turn will affect the P cycle in peatlands. This study aims to analyze the impact of land use to microbial P biomass and soil acid phosphatase activity. Soil samples were taken from three different land use systems, namely secondary forest, the 7-8 year old palm plantation and cassava fields. Microbial P biomass was quantified by using Chloroform Fumigation Extraction (CFE) method, while soil acid phosphatase activity was determined by using of colorimetric method. Microbial P biomass was high in the secondary forest site (274,27 μg P/g soil), and the lowest was in the cassava fields (72,68 μg P/g soil). Soil acid phosphatase was very active in the secondary forest site (40,58 μmolPNP/hours/g soil) and the lowest activity was found in the cassava fields (22,68 μmolPNP/hours/g soil). From the data, it can be concluded that land use affects the microbial P biomass and acid phosphatase activity in The Kampar Peninsula | en_US |
