Highlights: [•] Emissions of N2O and NH3 from cattle excreta on a Brachiaria pasture were compared. [•] Seasonal differences in N2O and NH3emissions from cattle excreta were assessed. [•] Fractions of N2O–N and NH3–N lost from urine were greater than from dung. [•] N2O emissions were greatest during the rainy season and minimal in the dry season. [•] Volatilization of NH3 was greater from urine than from dung and increased in the dry season. [Copyright &y& Elsevier]
