A new scientific paper from Teagasc has shown that getting soil pH right through a liming program can significantly reduce emissions of nitrous oxide (N2O), a potent greenhouse gas. The paper from researchers at the Teagasc Environment, Soils and Land-Use Department in Johnstown Castle, County Wexford has just been published in the scientific journal Agriculture, Ecosystems and Environment (AGEE). It concludes that increasing soil pH reduces fertilizer derived N2O emissions in intensively managed temperate grassland.
