SENSOR AND METHOD FOR DETERMINING OXYGEN SUPPLY IN THE ROOT

摘要

The present invention relates to a method for determining the oxygen supply in the subterranean parts of a plant, comprising the steps of capturing an initial condition of carotinoids in the form of a reference value using an aboveground part (9) of the plant by means of at least one light source (5) and at least one detector (7), supplying oxygen to the subterranean parts of the plants, determining a change in the carotinoids of an above ground part (9) of the plant in the form of a measured value; wherein a deviation of the measured value from the reference value indicates an oxygen deficiency in the subterranean parts of the plant. The invention further relates to a mobile sensor system (3) for determining the oxygen supply in the subterranean part of a living plant, and to the use of said sensor system (3) for securing or increasing the yield of crops and monitoring growth conditions in plants.
