The Lush Green Lie: Ireland's Famous Pastures Have a Potent Gas Problem
A deep dive into new research from the Journal of Environmental Management on how fertilizer choices for Ireland's pastures impact nitrous oxide emissions. Lear
By Foodie Pundit Newsroom - Published - Updated - Section: Agriculture Supply
Key points
- The type of nitrogen fertilizer used on pastures significantly changes when and how much nitrous oxide, a potent greenhouse gas, is released.
- High-nitrate fertilizers cause rapid, intense emission spikes in wet soil, while high-ammonium fertilizers lead to delayed, larger emissions later in the season.
- Simply switching fertilizer types is not enough; timing the application based on weather and soil moisture is crucial for reducing climate impact.
- Current short-term monitoring may underestimate the total environmental footprint of ammonium-based fertilizers due to their delayed emission patterns.
