| Outline of Final Research Achievements |
By extending the original implementation plan, the following three research outcomes are summarized:
「I. Cultivation experiments using Andisol, II. Relationship between artificial macropores and SOM (Soil Organic Matter) accumulation, III. 2D water movement analysis using Hydrus2D」Using the shaft tillage method, we measured the two-dimensional water flow, evapotranspiration, and CO2 concentration changes in the artificial macropore. To model organic matter decomposition, we developed and evaluated a CO2 concentration measurement system.
