    In-field soil spectroscopy represents a promising opportunity for fast soil analysis, allowing the prediction of several soil properties from one spectral reading representing one soil sample. This facilitates data acquisition from large amounts of samples through its rapidity and the absence of required chemical processing. This is of particular interest in agriculture, where the chance to retrieve information from soils directly in the field is very appealing. This review is focused on infield visible to near infrared (Vis–NIR) spectroscopy (350–2500 nm), aimed at analysing soils directly in the field through proximal sensing. The main scope was to explore the available knowledge to identify existing gaps limiting the reliability and robustness of in-field measurement, to foster future research and help transition towards the practical application of this technology. For this purpose, a literature review was performed, and surveyed information encompassed sensor range, carrier platforms in use, sensor type, distance to the soil sample, measurement methodology, measured soil properties and soil management, among many others. From this, we derived a list of tools in use with their spectral measurement properties, including the potential cross-calibration with soil spectral libraries from laboratory spectroscopy of soil samples and potential measured target soil properties. Different instruments and sensors used to measure at varying wavelength ranges and with different spectral qualities are available for a large range of prices. The most frequently analysed soil properties included soil carbon contents (soil organic carbon, soil organic matter, total carbon), texture (clay, silt, sand), total nitrogen, pH and cation exchange capacity. Future perspectives comprise the implementation of larger databases, including different instruments and cropping systems as well as methodologies combining existing knowledge regarding laboratory spectroscopy with in-field methods. The authors highlight the need for a broadly accepted measurement protocol for in-field soil spectroscopy, fostering harmonization and standardization and consequently a more robust application in practice.

    Review of Soil Threats and Soil-Related Ecosystem Services European Maps: Can We Use Them to Study Their Relationships?
    (Wiley, 2025-10-22) Reyes-Rojas, Jessica ; Montagne, David ; Saby, Nicolas P. A. ; Coblinski, João Augusto ; Pindral, Sylwia ; Medina-Roldán, Eduardo ; Lorenzetti, Romina ; Scammacca, Ottone ; Piccini, Chiara ; Borůvka, Luboš ; Cornu, Sophie
    The scientific concepts of soil threats (STs) and soil-related ecosystem services (SESs) are gaining importance and are fueling the debate on natural resources management and decision-making within the EU. The literature reports numerous assessments of individual STs and SESs at the European scale. However, a comprehensive overview of the patterns emerging from the relationships between STs and SESs is still lacking, which restricts the ability to limit soil degradation and its impact on SESs. In this article, we provide an in-depth analysis of existing European maps for three STs (soil organic carbon loss, erosion, and compaction) and four SESs (climate regulation and carbon sequestration, hydrological control, biomass production, and erosion control) and the feasibility of combining them to study their relationships. At the EU-level, 37 maps for these STs and 17 for these SESs were encountered. With the notable exception of erosion, these maps differ considerably in their conceptualization of STs and SESs, and in the indicators, methods, and databases used to assess them. In the current situation, the combination of individual maps of STs and SESs to study their relationships is rarely possible. Besides these limitations, we identify possible combinations and provide recommendations aimed at improving the compatibility between different STs/SESs maps. We conclude that there is a need for a more robust framework for conceptualizing STs/SESs and for systematically and precisely specifying the chosen indicators.
