Model-level dataset from a quantitative review of XRF-based soil property prediction and data-fusion approaches Vinicius Pires Rezende (20398475) Agricultural management of nutrients XRF sensor fusion soil fertility proximal sensing machine learning <p dir="ltr">This dataset contains the model-level database used in a quantitative review of XRF-based soil property prediction models and data-fusion approaches. The database was compiled from peer-reviewed studies published between 2012 and 2026. Each row represents one predictive model entry rather than one unique article.</p><p dir="ltr">The dataset includes information on the target soil attribute, sensor configuration, data-fusion level, fusion implementation strategy, modeling algorithm, preprocessing method, experimental environment, geographical scope, sample size, country, climate classification, soil texture information, and model performance metrics. The main performance metrics include R², RMSE, RPD, and RPIQ when reported in the original studies.</p><p dir="ltr">Sensor configurations were classified as XRF-only when the predictive model used only XRF-derived variables and as data fusion when XRF was combined with at least one additional source of information. Data-fusion approaches were harmonized into three main levels according to the stage at which information was integrated: low-level, mid-level, and high-level fusion. Feature-level and score-level approaches were grouped as mid-level fusion, whereas decision-level and ensemble-level approaches were grouped as high-level fusion.</p><p dir="ltr">The dataset supports the analyses, figures, and tables presented in the associated review manuscript on XRF-based soil property prediction and data-fusion strategies. The value of n reported in the manuscript refers to the number of model-level entries, not the number of unique articles.</p> 2026-09-14T14:21:45Z Dataset Dataset 10.6084/m9.figshare.33742555.v1 https://figshare.com/articles/dataset/Model-level_dataset_from_a_quantitative_review_of_XRF-based_soil_property_prediction_and_data-fusion_approaches/33742555 CC BY 4.0
