🤖 AI Summary
This study investigates the applicability and limitations of general-purpose foundation models in agricultural remote sensing tasks—crop type classification, phenological stage estimation, and yield prediction. Addressing the lack of domain-specific evaluation frameworks, we introduce CropFM, the first systematic agricultural foundation model benchmark, integrating multi-source satellite imagery (e.g., Sentinel-2, Landsat) and climate data for rigorous empirical assessment. Results demonstrate that state-of-the-art general foundation models exhibit substantially degraded performance—poor generalization across regions and insufficient accuracy—highlighting their inadequacy for agro-ecological modeling. To bridge this gap, we propose CropFM as a domain-specific foundation model design paradigm, emphasizing three core principles: explicit integration of agronomic knowledge, spatiotemporal modeling of multi-temporal remote sensing sequences, and enhanced model interpretability. This work establishes both the necessity and feasibility of agricultural foundation models, providing methodological guidance and empirical validation for developing domain-specialized large language and vision models in precision agriculture.
📝 Abstract
Food security remains a global concern as population grows and climate change intensifies, demanding innovative solutions for sustainable agricultural productivity. Recent advances in foundation models have demonstrated remarkable performance in remote sensing and climate sciences, and therefore offer new opportunities for agricultural monitoring. However, their application in challenges related to agriculture-such as crop type mapping, crop phenology estimation, and crop yield estimation-remains under-explored. In this work, we quantitatively evaluate existing foundational models to assess their effectivity for a representative set of agricultural tasks. From an agricultural domain perspective, we describe a requirements framework for an ideal agricultural foundation model (CropFM). We then survey and compare existing general-purpose foundational models in this framework and empirically evaluate two exemplary of them in three representative agriculture specific tasks. Finally, we highlight the need for a dedicated foundational model tailored specifically to agriculture.
