L2M – A high-sensitivity, field-portable laser-based probe for soil monitoring

We are developing a portable soil analysis system based on laser-induced breakdown spectroscopy (LIBS). During LIBS, an intense laser pulse generates plasma on the soil surface, and the emission from this plasma serves as a fingerprint of the soil’s elemental composition. The signal variability caused by the heterogeneous soils and challenges of quantifying complex composition are overcome by machine learning (ML) data modeling. This novel ML-LIBS device will significantly reduce the cost and processing time of soil analysis, supporting real-time monitoring of soil nutrients, composition, and fertilizer optimization for sustainable cultivation.
