“…The LIBS technique has many merits for sample analysis, including the fact that it is rapid, less destructive, cost-effective, environmentally friendly, little to no sample preparation is required, and simultaneous multi-element detection can be achieved [11][12][13]. Because of these outstanding advantages, the LIBS technique has been widely applied in various fields including space exploration [14][15][16], geological surveying [11,17,18], archaeological investigation [19][20][21], environmental monitoring [22][23][24][25], materials characterization [26][27][28], food detection [29][30][31], agriculture monitoring [32][33][34], and industry monitoring [35,36].…”

Accurate management of soil nutrients and fast and simultaneous acquisition of soil properties are crucial in the development of sustainable agriculture. However, the conventional methods of soil analysis are generally labor-intensive, environmentally unfriendly, as well as time- and cost-consuming. Laser-induced breakdown spectroscopy (LIBS) is a “superstar” technique that has yielded outstanding results in the elemental analysis of a wide range of materials. However, its application for analysis of farmland soil faces the challenges of matrix effects, lack of large-scale soil samples with distinct origin and nature, and problems with simultaneous determination of multiple soil properties. Therefore, LIBS technique, in combination with partial least squares regression (PLSR), was applied to simultaneously determinate soil pH, cation exchange capacity (CEC), soil organic matter (SOM), total nitrogen (TN), total phosphorus (TP), total potassium (TK), available phosphorus (AP), and available potassium (AK) in 200 soils from different farmlands in China. The prediction performances of full spectra and characteristic lines were evaluated and compared. Based on full spectra, the estimates of pH, CEC, SOM, TN, and TK achieved excellent prediction abilities with the residual prediction deviation (RPDV) values > 2.0 and the estimate of TP featured good performance with RPDV value of 1.993. However, using characteristic lines only improved the predicted accuracy of SOM, but reduced the prediction accuracies of TN, TP, and TK. In addition, soil AP and AK were predicted poorly with RPDV values of < 1.4 based on both full spectra and characteristic lines. The weak correlations between conventionally analyzed soil AP and AK and soil LIBS spectra are responsible for the poor prediction abilities of AP and AK contents. Findings from this study demonstrated that the LIBS technique combined with multivariate methods is a promising alternative for fast and simultaneous detection of some properties (i.e., pH and CEC) and nutrient contents (i.e., SOM, TN, TP, and TK) in farmland soils because of the extraordinary prediction performances achieved for these attributes.

“…The LIBS technique was successfully used (i.e., good correspondence with the reference technique, low error and LOD below the regulatory guideline values) to quantify toxic elements in soils (Akhtar et al, 2018;Ambushe et al, 2015;Barbafieri, Pini, Ciucci, & Tassi, 2011;Bousquet et al, 2007;Chen, Hei, Yu, Chen, & Cai, 2018;Dell'Aglio et al, 2011;Gao et al, 2018;Gornushkin et al, 1997;Hilbk-Kortenbruck et al, 2001;Khumaeni et al, 2017;Kwak et al, 2009;Lazic, Barbini, Colao, Fantoni, & Palucci, 2001;Menegatti et al, 2017;Meng et al, 2015Meng et al, , 2017Multari et al, 1996;Nicolodelli et al, 2018;Popov et al, 2010Popov et al, , 2014Senesi et al, 2009;Sirven et al, 2006;Srungaram, Ayyalasomayajula, Yu-Yueh, & Singh, 2013;Wang et al, 2018;Wisbrun et al, 1993;Yi et al, 2018;Zaytsev et al, 2018). The technique has been more sensitive than the reference technique when optimized or used with signal enhancement methods (Akhtar et al, 2018;Gao et al, 2018;Gornushkin et al, 1997;Hilbk-Kortenbruck et al, 2001;Khumaeni et al, 2017;Meng et al, 2015;Popov et al, 2010Popov et al, , 2014Yi et al, 2018). However, measuring toxic elements in soil samples is not easy with LIBS, because the intensity of the emission lines of these elements is generally weak…”

“…In addition to using more intense lines for each toxic element, three methods were developed to improve the sensitivity of the LIBS technique (Gao et al, 2018;Gornushkin et al, 1997;Hilbk-Kortenbruck et al, 2001;Khumaeni et al, 2017;Meng et al, 2015Meng et al, , 2017Popov et al, 2010Popov et al, , 2014Yi et al, 2018). The first consists of the use of laserinduced fluorescence-assisted LIBS (LIBS-LIF) to amplify the emission line intensity of an element (Gao et al, 2018;Gornushkin et al, 1997;Hilbk-Kortenbruck et al, 2001;Nicolodelli et al, 2018).…”

“…The physical confinement was used with the following elements: As, barium (Ba), Cd, Cr, Cu, Hg, Mn, Ni, Pb, vanadium (V) and Zn (Khumaeni et al, 2017;Meng et al, 2015Meng et al, , 2017Popov et al, 2010), whereas the magnetic confinement was used with Cr only (Akhtar et al, 2018). The third method consists of extracting the metals by means of acid and subsequent drying, a process known as the phase transformation method, which lasts >20 min, according to Yi et al (2018). With this method, the authors obtained very low LODs of 0.067 and 0.94 mg kg −1 for Cd and Pb, respectively.…”

In‐field soil health assessments, including plant nutrients and toxic elements, are needed and could improve the sustainability of agriculture production. Among the available analytical techniques for these analyses, laser‐induced breakdown spectroscopy (LIBS) has become one of the most promising techniques for real‐time soil analysis at low cost and without the need for reagents. The first part of this two‐part review (Part I, Villas‐Boas, P.R., de Franco, M.A., Gollany, H.T., Martin‐Neto, L. & Milori, D.M.B.P. 2019. Applications of laser‐induced breakdown spectroscopy for soil characterization, Part I: Review of Fundamentals and Chemical and Physical Properties.) in this issue focused on the fundamentals of LIBS for soil analysis and its use for soil chemical and physical characterization. Our objectives in this review article (Part II) are to review (a) the main applications of LIBS in the determination of soil carbon (C), nutrients and toxic elements, spatial elemental mapping, and (b) its use in soil classification. Traditional and more recent techniques will be compared to LIBS, considering their advantages and disadvantages. Laser‐induced breakdown spectroscopy is a promising, versatile technique for detecting many elements in soil samples, requires little or no sample preparation, takes only a few seconds per sample, and has a low cost per sample compared to other techniques. However, overcoming matrix effects is a challenge for LIBS applications in soil analysis, because most studies are conducted with limited changes in the matrix. In spite of the limitation of matrix effects, a typical LIBS system has a limit of detection of 0.3, 0.6, 4, 7, 10, 18, 46 and 89 mg kg−1 for Mo, Cu, Mg, Mn, Fe, Zn, K and Ca, respectively. Laser‐induced breakdown spectroscopy holds potential for real‐time in‐field spatial elemental analysis of soils and practical applications in precision farming with proper calibration. This could lead to immediate diagnoses of contaminated soil and inefficient nutrient supplies and facilitate well‐informed soil management, increasing agricultural production while minimizing environmental impacts. Highlights Laser‐induced breakdown spectroscopy (LIBS) is a fast analytical technique with great potential for elemental mapping of soils. Elemental analyses of soil and plants and soil classification by LIBS are reviewed. Soil and rhizosphere spatial elemental analyses by LIBS are presented. LIBS advantages, limitations and challenges are discussed for soil elemental analysis.

This review attempts to present a broad view of the technique laser-induced breakdown spectroscopy (LIBS), since its origin, fundamentals, sample preparation strategies, use of chemometric tools for data processing, the advantages and limitations with regard to qualitative and quantitative analysis, aplications and future trends as an analytical technique that is in consolidation in analytical chemistry. LIBS is a rapid and versatile, which is able of providing qualitative and quantitative analytical information for practically any sample, in a virtually non-destructive way, without any substantial sample preparation. The instrumentation is simple, robust, compact, and enables remote analysis. The advancement of the LIBS applications in the areas of agriculture, environmental, food, biological/pharmaceutical, forensic, metallurgy and electronic waste were discussed in detail in this review. We consider that this review will be an important tool concerning dissemination of the LIBS, mainly for audience of undergraduate courses, and disciplines related to instrumental analysis.
