Monitoring and Control of Water and Nutrient Supply in Closed Growing Systems

In a review approach, this paper introduces some of the a priori knowledge of water and nutrient supply systems. Extra attention is paid to growing systems and their relation to pollution of the environment. In some European countries the year 2000 will be a target to enforce the use of closed growing systems in greenhouses. A project — started in this framework — aims at the design of a management and control system for processes in greenhouses.
