Identification of stress factors in soil organic matter dynamics in humid regions and its utilization in agriculture

在湿润地区引入胁迫因子，可以改变土壤有机质动态的可能性进行了测试。两步分解模型包括溶解和矿化过程中的多糖分解和两步代谢的基质利用土壤微生物的积极评价量化的压力因素，如土壤酸度对过程的影响;和Michaelis-Menten动力学被成功地应用于描述个人的分解过程。土壤酸度是影响这两个过程的重要因素之一。

The possibility for introducing stress-factors that could modify the soil organic matter dynamics under humid regions was tested. Two-step decomposition model including both solubilization and mineralization processes in the decomposition of polysaccharides and two-step metabolism by soil microorganisms in substrate utilization were evaluated positively in quantifying influence of stress factors such as soil acidity on the processes ; and the Michaelis-Menten kinetics was successfully applied for describing individual decomposition processes. The soil acidity was considered to be one of most important factors that significantly affected both processes.
