A study by Teagasc state-backed agency Irish revealed fertiliser use between 2005 and 2015 declined as prices increased. The data examined the use of nitrogen, phosphorus, potassium and lime, and found in grasslands, nitrogen, phosphorus and potassium fertiliser application was between 11% and 16% higher during the earlier years of the study period, with declines of between 23% and 52% toward 2015. The lowest use was found during the high price period of 2008-2009. However, between 2005 and 2015, nitrogen application rates increased by 10% on cereal land.
