Operational management in pot plant production was investigated by means of system analysis and simulation. A theoretical framework for operational decision-making consisted of elaboration decisions, progress decisions, and adoption decisions. This framework was incorporated in a pot plant nursery model, which simulated the implementation of a give...
The application of digital image processing for grading of pot plants has been studied. Different techniques e.q. plant part identification based on knowledge based segmentation, have been developed to measure features of plants in different growth stage. Growth experiments were performed to identify grading features and to test whether it is possi...
Dynamics of water and nutrients as affected by physical and chemical characteristics of a substrate, fertigation method and schedule, and plant uptake were studied for a flooded bench fertigation system for potted plants, through a detailed experimental study of the root environment and a simulation model.Based on analogy with soils, a summary is g...
This thesis deals with the application of bench heating systems for potplant cultivation, which were developed for application of low temperature heating water from flue gas condensers and external waste heat sources. Compared to the traditional way of heating, a 'reversed' temperature gradient is created on heated benches, with a high root-zone te...
