New technologies that enable a reduction in NH3-N volatilization losses should be developed to increase the N use efficiency of urea. The incorporation of boron and copper into urea can reduce these effects by inhibiting urease activity. The experiment was conducted in a greenhouse, testing the application of different N fertilizers (urea pellets with and without boron and copper, ammonium sulfate, urea with urease inhibitor NBPT, granulated urea and urea coated with boron and copper) to the surface of a […]
