A new agricultural farming and management system is proposed, which is based on real time field monitoring of agricultural related information using a Field Server. The Field Server monitoring network system was developed at a vine yard at Obuse-town in Nagano, Japan. Data of environmental condition (solar-radiation, temperature, relative humidity, and soil moisture) and growth information (leaf and branch shapes, blooming, fruiting and size) were automatically collected by the Field Server and transferred to a personal computer inside a house through a wireless LAN which could connect the two places at a distance of about 300 m. These information are used not only for farming, but also for agri-tourism that is one of strategies for the Obuse's agricultural industry with sustainable development. Some ideas are also proposed for the data use
