1. Real-time monitoring of soil information in agricultural fields in Asia using Fieldserver Masaru Mizoguchi 1* Shoichi Mitsuishi 1 Tetsu Ito 1 Kazuo Oki 1 Seishi Ninomiya 2 Masayuki Hirafuji 2 Tokihiro Fukatsu 2 Takuji Kiura 2 Kei Tanaka 2 Hitoshi Toritani 3 Hiromasa Hamada 4 Kiyoshi Honda 5 1 st Global workshop on High Resolution Digital Soil Sensing and Mapping February 5-8, 2008, Sydney-Australia

2. What is Fieldserver? - To see is to believe - New technologies developed by NARO –National Agriculture and Food Research Organization An on-site field monitoring system –that collects data on crop, climate and soils in agricultural fields –and sends the data –along with high-resolution digital photos –to a laboratory via the Internet Each FS communicates through a Wi-Fi network

4. Soil information system by Fieldserver We use ECH 2 O as a standard soil moisture sensor

5. Soil sensor ECH 2 O soil moisture sensors measure –volumetric water content accurately and economically –the dielectric permittivity of the soil Benefits include: –TDR-level performance at a fraction of the cost –Very low power requirement –Easy installation at any depth and orientation http://www.decagon.com/ECH2O/

6. Experimental site in a rain-fed field in Northeast Thailand –Soil moisture distribution changes dynamically according to land use

7. Monitoring data Meteorological data –air temperature –humidity –radiation –wind speed –Precipitation Soil data at 4, 8, 16, 32 cm –soil moisture content –ground temperature –electrical conductivity Image data of the site

8. Diagram of real-time soil information monitoring system Soil data flow –Soil – sensor – (data logger) – Fieldserver – –Router – Satellite – AIT – NARO – UT

9. Data storage (AIT – NARO – UT) Real-time monitoring data sent from a rain-fed field Meteorological data are obtained as a xml-table and graphs

10. An example of soil monitoring data Precipitation Accumulated precipitation Soil temperature Soil moisture Water logging To see is to believe!

11. Other sites SRI site in Bogor, IndonesiaSpinach field in Chiang Mai, Thailand Cabbage field in Tsumagoi, JapanGlacial lake in Himalaya, Nepal

12. Soil moisture in Cabbage filed changes according to rain and vegetation Before harvesting (6/23) Harvesting(7/18) Cultivating (7/24)Planting (7/26) Growing (7/26) To see is to believe!

15. Application of agro-informatics to management of safe agricultural production Global observation data for agricultural production Tools for data fusion of agricultural information Collaboration between University and Institutes input Agricultural production supporting tool considering propagating information (1997-2000) Collaboration system of DB and model (2001-2005) Climate prediction by model Vegetation data by satellite Meteorological data History of agricultural crop management Data Integration and Fusion System Link to models Rice growth model Soil water prediction model Ecosystem model Early-warning system for cold- weather damage Check system of right crop for right land system Societal Benefits Information based on knowledge from scientific data and models ↓ Low-cost, high-quality and safe agricultural production How much pesticide should we spread? Most appropriate day Seeding, planting, fertilizing Soil moisture control Prediction of the best cultivation day future vegetation of cabbage Decision by agricultural information Future application Solution of food and environmental issues in the world Real-time observation data in agricultural field Tools for data collection

16. Conclusions - Fieldserver - is a new technology for spatial measurement of agricultural field has a great potential for soil Information monitoring waits for the development of powerful and useful sensors: –ECHO-TE (Soil moisture, Soil temperature, EC) –Nitro-sensors (NH 4, NO 3, NO 2, etc)? –GHG-sensors (CH 4, N 2 O, etc)? will bring precision agriculture a big chance under the National project related to the 10-year Implementation Plan for GEOSS
