TL;DR
This study introduces a novel sampling design that integrates local soil heterogeneity in both geographical and feature spaces to improve farm-level soil property mapping. It addresses limitations of current methods by considering both spaces simultaneously for more robust sampling.

Sampling design plays a crucial role in managing soil variability at the farm level by ensuring the collection of reliable soil samples. Current methods focus on optimizing sample size and locations within geographic or feature space, taking a global perspective. However, treating geographic and feature space separately diminishes the robustness of the sampling design against deviations from the a...
