Potential title: Evaluating the profitability and productivity of enhanced efficiency fertilizers (EEFs) on irrigated winter wheat systems
Barrier: There is limited data on the cost-benefit analysis of the use of EEFs on a fall-seeded cereal crop under irrigation in the Prairies.
Field Trial description:
This study aims to evaluate the use of EEFs in irrigated winter cereal systems in southern Alberta. A replicated strip trial will compare two rates of fall-applied urea (at 100% and 80% the recommended rate) with and without the use of a dual inhibitor (Anvol and Centuro U-Pro) to a check (with no nitrogen). Soil samples, emergence counts, canopy closure, vigour, biomass and aerial imagery will be captured, grain yield and quality will be measured and nitrogen use efficiency and profitability will be calculated. The project assesses strategies to reduce nitrogen losses, reduce operational expenses while maintaining yields for overall increased profitability.
