| Abstract: | This paper aims to develop a vehicular integrated system collecting soil electrical conductivity(EC) and spectral reflectance.The system could collect soil EC and spectral reflectance automatically when the vehicle moves and save these measurement results with GPS.The information could reflect the characteristics of soil parameters such as soil salinity and water content.Hence, an Android-based vehicular detection system for soil conductivity and spectral reflectance information was developed.Soil electrical conductivity measurement was performed based on improved "current-voltage" four-terminal method.A STS-NIR spectrometer was used for collecting near-infrared spectral reflectance.The system collected the information of soil electrical conductivity and soil spectral reflectance while collecting GPS, which could be used for precision agriculture.The system was tested in a farm of Beijing on March 25, 2014.Soil electrical conductivity of the farmland was measured and soil samples were collected.Water content and soil electrical conductivity were measured in the laboratory.The result of these experiments showed that the system could work stably in farmland and had good prospects. |
