      A major responsibility of the research staff at Johnstown Castle has been the publication of leaflets, booklets and manuals giving nutrient and trace element advice for grassland and crops. This began in the 1940s and was the scientific basis for soil analysis (Coulter 2000), since then, further updates were published by Coulter in 2004 (2nd edition), by Coulter and Lalor in 2008 (3rd edition) and by Wall and Plunkett in 2016 (4th edition. This version has now been enhanced and expanded to produce the present volume (5 th edition) published by Wall and Plunkett in 2020. New sections and information and updates based on the latest scientific findings have been made to grassland fertiliser advice section including nitrogen advice for grass–white clover swards. Many of the chapters have been reorganised to make them easier to consult and the advice and tables have been redesigned to be compliant with the latest European and Irish legislation.
    • Precise Application of Fertiliser

      Forristal, Dermot; Plunkett, Mark (The Fertilizer Association of Ireland in association with Teagasc, 2017-05)
      The role of the fertiliser spreader is often under estimated in the delivery of fertilisers (N, P & K) as evenly and as accurately as possible. Fertilisers are a significant cost in grassland and tillage farming systems, representing between 20 to 30% of total production costs for either a cereal or grass silage crop. There are many steps involved in determining the actual rate of fertiliser from soil sampling to preparing a fertiliser plan. To profit from fertiliser planning it is essential that fertilisers are applied precisely and accurately. There are a number of factors to consider before spreading fertiliser such as: 1. Selecting the correct machine for the bout width and fertiliser to be used 2. Using good quality fertiliser 3. Correct setting of the machine Technical bulletin No. 3 produced by the Fertilizer Association of Ireland in conjunction with Teagasc identifies the steps to consider for the precise application of fertilisers to optimise farm profitability and sustainability.
    • Teagasc submission made in response to the Consultation Paper on Interim Review of Ireland’s Nitrates Derogation 2019

      Spink, John; Buckley, Cathal; Burgess, Edward; Daly, Karen M.; Dillon, Pat; Fenton, Owen; Horan, Brendan; Humphreys, James; Hyde, Tim; McCarthy, Brian; et al. (Teagasc, 2019-06-04)
      This submission was made in response to the consultation process run jointly by the Department of Housing, Planning, Community and Local Government (DHPCLG) and the Department of Agriculture, Food and the Marine (DAFM) inviting views and comments on proposals for the Interim Review of Ireland’s Nitrates Derogation Programme in 2019. It has been prepared by Teagasc’s Water Quality Working Group in consultation with the Gaseous Emissions Working Group. These working groups have members drawn from both the Knowledge Transfer and Research Directorates of Teagasc. It was prepared following consultation with colleagues across Teagasc using their collective knowledge and expertise in agri-environmental science and practice and the implementation of the Good Agricultural Practice (GAP) and Nitrates Derogation Regulations.
