Laser-induced breakdown spectroscopy (LIBS) uses a focused laser pulse to heat, ionize, and vaporize the target material by converting it into a hot plasma. The plasma emits light which is detected by a camera and processed by a spectrograph and computer software. Using known standards to determine retention times, LIBS provides excellent qualitative data on several common soil micro- and macro-nutrients. In this study we quantitatively examine LIBS precision and accuracy for several Tennessee soils compared to values obtained by inductively coupled plasma.
