Determination of soil properties is based on soil sampling with low resolution (1- 2 or more samples per hectare) and their analysis in the laboratory. This method does not provide sufficient data to highlight the significant variability of the soil properties for the analysed parcel. This leads to a uniform distribution of the nutrients that can also be synthetic chemical substances (pollutants). Since the soil properties can influence plants growth, high-resolution mapping is required by the help of some sensors...
