Prediction of Soil Properties at Field-Scale for Site-Specific Management: Model Comparison and Spatial Diagnostics

This study compared machine learning (ML), geostatistical, and hybrid methods for predicting soil organic matter (SOM), cation exchange capacity (CEC), and nitrogen using remotely sensed, topographic, and soil survey covariates to support targeted soil management at the field-scale. Using nested cross-validation, we fo...
