A mobile-phone based field logging system for high quality Satsuma mandarin production

Satsuma Mandarin cultivated in Nanki, Mie, Japan is one of the most excellent rareripes. However, lack of agricultural continuators makes the translation of special agricultural skills much harder. Under these circumstances, advanced application of ICT to Mandarin production using the scientific evidences based on the sensing data is eagerly desired. In this sense, collaboration between ICT system developers and Mandarin growers should be necessary with sharing common understanding for the sustainable production of excellent Satsuma Mandarin based on the index for optimal irrigation control with sensing data. In this paper, we introduce a mobile-phone based data logging system with small rubber ball apparatus is proposed for cost effective way to collect cultivation diagnosis for Satsuma mandarin production. The data are collected to the server via internet and bring to each field worker via Web-based time-line UI, where they can compare other data such as temperature, the amount of isolation collected by local weather robot or reference user´s data. The system was applied to a test field at test site in Kumano, Mie, Japan. In this paper, therefore, we tried to apply cutting-edge.
