Zinc oxide nanoparticles coated urea enhances nitrogen efficiency and zinc bioavailability in wheat in alkaline calcareous soils.

Nitrogenous fertilizers have low efficiency in alkaline calcareous soils due to volatilization and denitrification. These losses cause economic environmental constraints. Coating of urea with nanoparticles (NPs) is an innovative strategy to improve crop yields by sustaining N availability.
