Managing Fertiliser Decisions in Dry Conditions

John O’Loughlin, Head of Sustainability at Grassland Agro, joins Stuart Childs to discuss the impact of CBAM, fertiliser advice in dry conditions and two upcoming farm walks that will be worth attending this July. John first explains the EU's Carbon Border Adjustment Mechanism (CBAM) which is adding approximately €50/t to urea in 2026, with the potential to rise significantly in future years. While there has been discussion about suspending the charge during periods of high fertiliser prices, he believes this now looks unlikely, meaning farmers should expect CBAM to remain a factor in fertiliser costs. John recommends that farmers measure grass regularly and make decisions based on their own farm’s situation, as drought conditions are varying widely across the country from his perspective and one size won’t fit all in terms of advice.  Where soil moisture deficits become severe, nitrogen applications should be reduced or paused, but where growth remains good, protected urea is still a good choice as it will absorb water from the atmosphere. John stresses that potassium (K) and lime are essential for helping grass cope with drought and recover quickly afterwards. John describes K as the "engine oil" of the plant because of the role it plays in the movement of water and nutrients, and he says that correcting K and lime deficiencies are among the biggest, most cost-effective improvements farmers can make to maximise grass growth and resilience. Finally, John says listeners should consider attending two good days later this month in the Clonmel area with the Irish Grassland Dairy Summer Tour taking place on the farms of Michael and Ollie O’Gorman on the 21st and then the Tipperary Dairy Calf to Beef Open Day the following day at the Ballyvadin Farm near Fethard. For more episodes from the Dairy Edge podcast go to the show page at:https://www.teagasc.ie/animals/dairy/the-dairy-edge-podcast/ The Dairy Edge is a co-production with LastCastMedia.com
