Does dust affect the sensor reading?
Dust will not normally affect the NDVI readings because dust impacts the reflectance of red and NIR similarly. The RT200 system monitors the sensors for proper operation, if a sensor reports erroneous data, the data is not include in the calculation for fertilizer rate control. The GreenSeeker® diagnostics will also provide a warning if a sensor is “blinded”. The operator should wipe the sensor’s lenses clean each time he/she checks the nozzles.
