One of the techniques that is considered promising for measuring soil textural properties based on the results of the NewField project is gamma spectrometry. The natural radioactivity or gamma radiation that is measured is a measure for, among other things, the clay content of the soil. This data is validated in a field test comparing results for clay content and other textural classes using only sampling results, sampling results and driving (proximal) gamma spectrometer measurements, sampling results and flying (UAV) gamma spectrometer measurements. We will take into account the differences in result, accuracy, detail and cost of acquisition. Thus it can be determined whether this is a relevant technique for deploying in gathering data for the soil map update and retrieving soil property information.
