Development of a hyperspectral imaging technique using LA-ICP-MS to show the spatial distribution of elements in soil cores

Data set showing the development of a hyperspectral imaging technique using LA-ICP-MS to determine the spatial distribution of nutrients in soil cores

“…Spatial distribution of nutrients was measured by laser ablation inductively coupled plasma mass spectrometry (LA‒ICP‒MS), using the new techniques we developed to visualize nutrient distribution in intact soil cores representative of the root rhizosphere. This data article supports the findings published in the main article [1] . This work also demonstrates that LA-ICP-MS is a valuable technique to image the spatial distribution of macro and micronutrients in intact soil cores as affected by different crop management practices.…”

“…Laser ablation inductively coupled plasma mass spectrometry (LA-ICP-MS) is a very efficient and sensitive surface nutrient imaging technique that can be used to discern the spatial distribution of metals and non-metals in biological and environmental samples [1] . This data set contains information regarding the effect of four different agronomic practices on the spatial distribution of nutrients in the plant root zone.…”

“… This data in brief article represents the data set associated with a research article published in Geoderma [1] . The data set represents figures showing the spatial distribution of selected macro and micronutrients, and their quantification in different crop or nutrient management systems practiced in the boreal ecosystem.…”

Significance of phosphorus inclusions and discrete micron‐sized grains of apatite in postglacial forest soils

“…Laser ablation inductively coupled plasma mass spectrometry (LA–ICP‐MS) imaging is a relatively new elemental characterisation and visualisation tool in soil analysis (Arroyo et al, 2009; Arroyo et al, 2010). It is increasingly gaining attention as a sensitive analytical technique with imaging capabilities to characterise the compositions, concentrations, and distributions of multiple elements in soil microsites (Santner et al, 2015; Zaeem et al, 2021). In principle, an LA‐ICP‐MS system consists of a laser that is used to ablate a sample, which is analysed for elemental composition by an inductively coupled plasma mass spectrometer.…”

“…In principle, an LA‐ICP‐MS system consists of a laser that is used to ablate a sample, which is analysed for elemental composition by an inductively coupled plasma mass spectrometer. The system can be used to generate elemental images by proper synchronisation of the laser ablation unit and the ICP‐MS to record transient element intensities at discrete positions on the sample (Santner et al, 2015; Zaeem et al, 2021). Despite the analytical sensitivity, affordability, and high availability of LA‐ICP‐MS for soil analysis (compared to synchrotron X‐ray absorption spectroscopy), the extent to which (semi)quantitative and multi‐elemental LA‐ICP‐MS imaging could be used to deduce soil P abundance, distribution, and speciation, either as a standalone analytical system or in combination with synchrotron XAS, is yet to be investigated.…”
