Multispecies Swards: Benefits of Diversity for Farming

Growing high-quality grassland swards is vital for milk and meat production in Irish agriculture. For better harvest yields, nitrogen fertiliser is typically added to grassland. However, high levels of nitrogen fertiliser is associated with high levels of greenhouse gas emissions, and there is considerable pressure to reduce fertiliser use. At Teagasc, we are investigating more environmentally sustainable grassland swards by mixing grass with different clovers and herbs, which can bring multiple benefits to both farmers and the environment.
