“…As the plasma cools, the continuum emission reduces, allowing the observation of atomic and ionic lines derived from the excited elements (Singh and Thakur, 2007), which is usually performed at~10,000 K. The elemental composition of the samples can be determined, and with appropriate calibration models the elemental concentration can be obtained. In the case of soil analysis, the LIBS has been applied to evaluate nutrients (Hussain et al, 2007;Ferreira et al, 2011;Braga et al, 2010;Cremers et al, 2001;Ebinger et al, 2003), contaminants (Bousquet et al, 2007;Senesi et al, 2009), and carbon (Nicolodelli et al, 2014;Ebinger and Harris, 2010;Silva et al, 2008), as well as humification degree of soil organic matter (Ferreira et al, 2014), soil pH (Ferreira et al, 2015), and soil classification (Pontes et al, 2009). However, no applications of LIBS have been reported for the evaluation of any soil physical characteristics.…”

The analysis of soil texture is crucial for the proper management of agricultural systems and for environmental studies. Soil texture is important as it affects erosion potential, water retention capacity, organic matter complexation, and the retention of nutrients, among others. It is usually determined by pipette or hydrometer methods, but analysis requires a preparation with chemical reagents, which can take hours and hence is unfeasible for large number of samples. Here we propose the use of laser-induced breakdown spectroscopy (LIBS) to estimate the proportions of sand, silt, and clay in 60 Brazilian soil samples of varying composition. Two calibration models were developed with the partial least square regression method: one considering the spectral region from 188 to 980 nm and the other, emission lines of the elements Si, Na, Fe, Ti, Ca, K, Al, Co, Mg, V, Ba, and Be. The Pearson correlation coefficients for the estimated values were 0.89 and 0.90 on average for the first and second models, respectively. The uncertainties were 6% on average for both models. These results demonstrate the use of LIBS for rapid scanning of the texture of soil samples with distinct composition. The procedure presented here can be extended to other chemical and physical soil properties, which makes LIBS a universal tool for rapid soil analysis without preparation with chemical reagents.

ARTICLE INFO ABSTRACTArticle history:The hardness of surface treated magnesium alloy was evaluated using laser induced breakdown spectroscopy. The surface of the specimen was hardened mechanically, and the hardness profiles were measured using a traditional measurement technique. A laser beam was irradiated to generate a plasma, and the peaks of the components of the specimen were analyzed. A wavelength of 333.66 nm and 293.65 nm were selected as the atomic and ionic peaks, respectively. The ratios of the ionic peak to the atomic peak were obtained so as to compare the hardness profile. As the depth increased, the ratio decreased. These results are in good agreement with the previous hardness measurement results. It can be considered that this technique could be applied for remote and time-efficient hardness measurement.
