| Outline of Final Research Achievements |
Soil is the complex system consisting of inorganic substance (minerals, ions), organic substance (plant residue, humus), and biota including microorganisms. In this study, we developed an artificial soil as a tool to answer the fundamental questions "what is soil?". Our artificial soil was synthesized by combining different biotic and abitic elements composing rice field soil. The artificial soils with different combination of soil components were analyzed for the activity of anaerobic decomposition of organic matter. The study revealed that humic substances have a great impact on the activity of the artificial soil. Finally we succeeded in creating the artificial soil that shows a comparable activity to the original soil. The artificial soil and its recipe developed in this study would be useful to study the role of each component in soil functions.
