Process-Model-Supported Offline Reinforcement Learning for Water–Fertilizer Management: Two-Model Closed-Loop Production–Nitrogen-Loss Trade-Offs

Nitrogen leaching threatens groundwater quality, making production retention and efficient water–fertilizer use joint management priorities. Field trials evaluate a limited set of treatments, while adaptive policies generate long sequences of decisions. We propose counterfactual rollout-constrained offline reinforcemen...
