From Simulation to Discovery: AI Enabled Probabilistic Emulation of Mechanistic Crop Systems
arXiv:2605.22848v1 Announce Type: cross Abstract: Global food security depends on predicting crop responses to climate variability, yet process based crop models remain too computationally expensive for large scale exploration of genotype and environment interactions. Here we develop a probabilistic neural emulator of APSIM that reproduces key maize growth processes across 13 outputs with high fidelity (with R^2 of 0.93) while reducing simulation time by several orders of magnitude. Trained on two million simulations spanning diverse genetic, soil, and management conditions, and augmented with
Advances in AI, particularly neural emulators, are reaching a point where they can significantly accelerate complex scientific simulations, moving from research to practical application in critical fields like agriculture.
This development can drastically improve global food security by enabling rapid, large-scale prediction of crop responses to climate models, leading to more resilient agricultural practices and optimizing resource allocation.
The computational barrier to exploring genotype and environment interactions in crop systems is significantly reduced, opening new avenues for agricultural research and decision-making that were previously too expensive or slow.

AI-accelerated crop models will enable faster development of climate-resilient crop varieties and optimized farming strategies.
Improved predictive capabilities will lead to more stable food production, potentially mitigating price volatility and reducing instances of famine caused by climate variability.
The success in agriculture could inspire similar AI emulation approaches across other complex biological and environmental systems, leading to a new era of 'in silico' scientific discovery.
