| Outline of Final Research Achievements |
In this study, an estimation of carbon storage in soil of agricultural area was made using the satellite data of 1985, 2001, 2012, 2013 and the carbon amount measured from soil samples collected from soil 0-30cm in depth.It became clear that the estimation of soil carbon storage was possible using data on reflection of wavelength in visible.Then, prediction of carbon storage change in future was calculated through Roth C model, using the soil carbon amount estimated from satellite data as the initial value for the model. As a result, in case the initial value is high, the predicted value decreases in the future while the initial value is low, the predicted value increases. In addition, the dried soil shows a tendency of decrease in soil carbon.Moreover, the increase or decrease in soil carbon is influenced by with or without underdrainage system.
