Managing urea price risk is a concern of firms in the urea supply chain due to high price volatility and relatively slow transportation. This study develops urea price forecasting models as a way to reduce price risk. The forecasting models are evaluated based on multiple accuracy measures and compared to Fertilizer Week, a commercial forecast. An autoregressive model with exogenous variables (ARX) using a window size of 48 months outperforms the other models. No statistical difference exists between our best model and Fertilizer Week. Encompassing tests show that a combination model using the two models outperforms using Fertilizer Week forecasts alone. A combined model using 66.8% of $$ Fertilzer\, Week $$FertilzerWeek and 33.2% of the ARX brings about the minimum forecast error.
