A two-year study in a Sichuan citrus orchard found polyurethane-coated urea cut ammonia losses by 51.1% and nitric oxide emissions by 36.3% versus conventional urea, and raised fruit yield in the second year. Humic acid urea increased nitrous oxide emissions by 16.1%.
Controlled-release urea improves nitrogen efficiency, which could modestly reduce demand for conventional urea over time. Urea prices in Brazil are rising after a thin Indian tender, keeping nitrogen costs high for growers.
After 26 past neutral report events, Urea moved a median -0.4% over 5 sessions (42% higher; middle half -4.1% to +1.5%), and +0.9% over 20.
