Highlights
• Grazing pastures when soils are wet increases N2O emissions from cow urine
• Duration controlled grazing (DCG) was applied when a soil ϴv threshold was reached.
• Different durations were assessed for farms on poorly and imperfectly drained soils.
• For poorly drained soils, DCG reduced N2O and manure-derived CH4 emissions.
• For imperfectly drained soils, DCG increased N2O and manure-derived CH4 emissions.
