An environmental and economic assessment on the impact of possible reductions in the maximum chemical nitrogen allowances for main arable crops

Environmental and economic modelling of the impact of adjustments in the maximum stocking rates permitted under Ireland’s Nitrates Derogation

Teagasc was asked by the Department of Agriculture, Food and the Marine to model the environmental and economic impacts of potential changes to stocking rates under Ireland’s Nitrates Derogation. The research will inform the 2026–2029 Nitrates Action Programme and Government’s discussions with the European Commission and fellow Member States on securing an extension to Ireland’s Nitrates Derogation.

Improving slurry nutrient distribution on dairy farm holdings

This report modelled milking platform stocking rates where nutrients must be distributed to other parts of the farm outside the milking platform in order to optimise nutrient use efficiency and reduce potential loss to the environment, based on the platform stocking rates, chemical N application rate and cow banding.
