8. 4.Precision agriculture project is conducted by National Engineering Center for Information Technology in Agriculture (NECITA), Chinese Academy of Agricultural Sciences (CAAS), and China Agricultural University (CAU). 5.Livestock farming project is conducted by CAAS and CAU.

9. Precision Agriculture Project  Field server as an environmental measurement or control system is used in protected plant production system such as greenhouse, tissue- culture room and plant factory.  Field server as a remote sensing device combined with GIS and GPS is used in the field crop production.  Field server as a digital device is used to automatic irrigation and hydroponics. Field Server and GIS Net-Camera

10. Livestock Farming Project  Field server as a environmental monitoring system is used in livestock farming to realize the remote sensing and wireless communication.  Poultry-population-weight measuring system using image sensor driven by the field server will be challenged.  Cattle-weight measuring system combined with the field server and RF-IC is to obtain and transfer the individual information.

11. Remarks  Various field monitoring servers as the digitalization infrastructures are very useful for ubiquitous and global sensing, computing and networking in agriculture.  The field monitoring server will be applied and improved in China in the near future.
