utilization were examined based on the soil moisture distribution map. We attempted theapplication of sensors from the plant physiological and farmer’s perspective. Both attemptsdescribed in this paper showed that more of the studies on collecting high precision data, therelation between the data and plant or fruits are much more required. In addition to thecollection of accurate data, it was revealed that the suitable usage of sensors in Japaneseagricultural fields, especially soil moisture sensors should be established.We developed web application software providing data to users. The application wasdesigned to enable users for monitoring field, referring past data in both numerical andgraphic representations, and download data. Additionally, AMeDAS based data representingwebpage was developed for satisfying one of the farmer’s needs. By this attempt, we couldpresent one of the examples showing merging and utilizing data collected by differentdevices on the web. However, it was clarified that more of the studies on data utilizationbased on plant physiology are necessary for cultivation support and high quality mandarinproduction. Additionally, transforming from implicit knowledge into formal knowledge is alsonecessary. Then, web application should be developed with the composition of visual andcomprehensive information from the database and the mathematical models, and it shouldprovide users information for intuitive operation. Furthermore, sensor network and webapplication could also be applicable for smart viticulture management (Togami et al., 2011b).AcknowledgementsThis work was supported by KAKENHI (Grant-in-Aid for Scientific Research (B) 21380161).We also acknowledge financial support from MAFF for the execution of these studies.Reference listFujita, A., Nakamura, M., & Kameoka, T.
