An exploration on heavy metal Pb2 + detection method was presented based on Terahertz (THz)Spectroscopy, which is rapid and maybe portable and low cost for future in-field applications.Theresults show that the optimized models are able to predict soil heavy metal Pb2+ content with acorrelation coefficient of 0.81. The method of using THz technology for soil heavy metal Pb2+ detectionis feasible. With the detection results, it can be found the heavy metal Pb2 + pollution spatialdistribution information of the soil in-field and get the "pollution map". Specific measures shall betaken based on the "pollution map" to manage the soil to improve the farmland productivity. This studywill provide a reference for heavy metals pollution detection solutions for precision farming andsustainable agriculture development.

Information related to how easy it is to start using the SFTThis SFT replaces a tool or technology that is currently used. The SFT is better than thecurrent tool no opinion

The SFT can be used without making major changes to the existing system no opinionThe SFT does not require significant learning before the farmer can use it disagreeThe SFT can be used in other useful ways than intended by the inventor no opinionThe SFT has effects that can be directly observed by the farmer no opinionUsing the SFT requires a large time investment by farmer no opinionThe SFT produces information that can be interpreted directly no opinion
