Facility
Imspector for mobile measurement of crop characteristics
Various methods, based on measurement of crop characteristics, can be used in projects aimed at restricting nutrient losses or crop-dependent application of crop protection products.
PRI aims at the development of new high-resolution sensing techniques for non-destructive on-line measurement of crop characteristics.
The application of stationary and mobile sensor technology is based on a complex optical system that separates light passing the unit into wavelengths. Wavelength-separated light is projected on the CCD of a camera after which the obtained data are analyzed. The system can determine characteristics down to a tenth square millimetre of the measured surface. When monitoring grassland fields in grazing experiments, e.g., biomass, sward quality (soil cover), N status, moisture status, feeding quality, clover percentage, grass/clover condition are investigated. The mobile version is fitted with GPS which enables fast and accurate handling, at the correct coordinates, on the basis of the measured values.
