Calibrating Biophysical Models for Grape Phenology Prediction via Multi-Task Learning

arXiv:2508.03898v2 Announce Type: replace Abstract: Accurate prediction of grape phenology is essential for timely vineyard management decisions, such as scheduling irrigation and fertilization, to maximize crop yield and quality. While traditional biophysical models calibrated on historical field data can be used for season-long predictions, they lack the precision required for fine-grained vineyard management. Deep learning methods are a compelling alternative but their performance is hindered by sparse phenology datasets, particularly at the cultivar level. We propose a hybrid modeling appr

Why this matters
Why now

The increasing availability of AI techniques and the pressing need for resilient agriculture due to climate change are driving innovations in biophysical modeling.

Why it’s important

Improved predictive accuracy in agriculture, particularly for high-value crops like grapes, can significantly enhance resource management, yield, and overall economic stability for growers.

What changes

The precision and reliability of vineyard management decisions can be substantially improved through hybrid AI-biophysical models, reducing waste and optimizing output.

Winners
  • · Viticulture industry
