Abstract
Gases (e.g. oxygen) in the root environment are an important factor for plant development.
This study aims to show whether it is possible to obtain an overview of oxygen profiles within the root zone using a limited amount of oxygen measurements in the root environment.
A further aim was to demonstrate whether this technology can be used to develop a measurement tool for practical use.
Therefore, a multi-oxygen sensor was constructed, and measurements were carried at two locations.
In the greenhouse, oxygen measurements were carried during growth of roses at various horizontal and vertical positions in pots, filled with stone wool blocks.
In the field, oxygen levels were detected in 3 L pots in a Rhododendron crop using peat as a growing medium.
Here, optical oxygen sensors were positioned at 3 cm above the bottom, and also in the middle of the pots.
The results indicate that it is possible to develop an oxygen measuring strategy which can be used to determine a representative pattern of oxygen levels in growing media.
Relationships between and related growth conditions will be described, and it will be discussed for which cultivation systems oxygen measurements should have priority.
