  Effect of burning on soil organic matter content and N mineralization under shifting cultivation system of Karen people in Northern Thailand

  摘要：

  In the traditional shifting cultivation system practiced by the Karen people in northern Thailand, the effects of burning on the content of extractable organic matter, microbial biomass, and N mineralization process of the soils were studied. Five plots (5 x 5 m(2) quadrat) with 0, 10, 20, 50, and 100 Mg ha(-1) of slashed materials were arranged and burned. Ten to 20 Mg ha(-1) of slashed biomass corresponded to the amount commonly burned by the Karen people. During the burning process, the soil temperature at the depth of 2.5 cm in the 100 Mg ha(-1) plot almost evenly increased to 300 degreesC while the temperature in the 10 to 50 Mg ha(-1) plots increased with large variations from 50 to 300 degreesC. Burning caused a conspicuous increase in the contents of organic C and (organic+ mineral)-N extracted at room temperature and a simultaneous decrease in the contents of microbial biomass C and N, especially in the soil of the 100 Mg ha(-1) plot. In the rainy season, the values of the changes induced by burning reverted to the values recorded before burning, except for the microbial biomass in the 100 Mg ha(-1) plot, which still remained lower. Based on an incubation experiment, N mineralization rate was higher in the soils taken just after burning, especially in the 100 Mg ha(-1) plot, than in the soils taken during the rainy season. However, the soil in the 100 Mg ha(-1) plot was considered to have the lowest ability to supply mineral N among the soils in the rainy season. Burning of 10 to 20 Mg ha(-1) biomass corresponding to the values recorded in Karen peoples' shifting cultivation system was more compatible with soil ecology in terms of N supply at the initial stage of crop growth and of microbial biomass recovery during the rainy season, compared to the burning of 100 Mg ha(-1) biomass corresponding to the value recorded in a natural forest. Thus, the shifting cultivation system implemented by the Karen people can be considered to be a well-balanced agricultural system.
