Description
Accurate crop yield prediction is critical for sustainable food production amid growing climate variability. This study assesses whether integrating UAV-derived surface reflectance, terrain attributes, and subsurface soil properties improves yield prediction in a terraced agroecosystem in the U.S. Midwest. A machine learning framework was developed using multispectral and RGB imagery, terrain metrics (slope, curvature, topographic position index), volumetric water content (VWC) from ground-penetrating radar, and apparent electrical conductivity (ECa) from electromagnetic induction. Surface reflectance alone produced limited predictive accuracy (R2 = 0.42), while adding terrain attributes significantly improved model accuracy (R2 = 0.86). Subsurface soil properties further enhanced prediction, with ECa providing the strongest improvement (R2 = 0.95). The highest performance was achieved when all datasets were integrated (R2 = 0.96). These results demonstrate that combining surface and subsurface information improves yield prediction and supports data-driven management to enhance agricultural productivity while preserving resources.
