“…Laser-induced breakdown spectroscopy (LIBS) is a recently developed spectral detection technique [ 6 ]. Because of the advantages of fast analytical speed, simple sample pretreatment, multi-element simultaneous detection capability, as well as the potential of in situ or stand-off analysis [ 7 ], it has been widely used for the elemental analysis of various kinds of samples, including plants [ 8 ], water [ 9 ], and especially soils. Martin et al applied LIBS to determine the carbon and nitrogen content of various soils, and the good results proved that LIBS technique had the potential to be packaged into a field-deployable instrument for real-time and in situ analysis of soil carbon and nitrogen [ 10 ].…”

Rapid detection of soil nutrient elements is beneficial to the evaluation of crop yield, and it’s of great significance in agricultural production. The aim of this work was to compare the detection ability of single-pulse (SP) and collinear double-pulse (DP) laser-induced breakdown spectroscopy (LIBS) for soil nutrient elements and obtain an accurate and reliable method for rapid detection of soil nutrient elements. 63 soil samples were collected for SP and collinear DP signal acquisition, respectively. Macro-nutrients (K, Ca, Mg) and micro-nutrients (Fe, Mn, Na) were analyzed. Three main aspects of all elements were investigated, including spectral intensity, signal stability, and detection sensitivity. Signal-to-noise ratio (SNR) and relative standard deviation (RSD) of elemental spectra were applied to evaluate the stability of SP and collinear DP signals. In terms of detection sensitivity, the performance of chemometrics models (univariate and multivariate analysis models) and the limit of detection (LOD) of elements were analyzed, and the results indicated that the DP-LIBS technique coupled with PLSR could be an accurate and reliable method in the quantitative determination of soil nutrient elements.
