Journal ArticleDOI
Management, regulation and environmental impacts of nitrogen fertilization in northwestern Europe under the Nitrates Directive; a benchmark study
H. van Grinsven,H.F.M. ten Berge,Tommy Dalgaard,B. Fraters,Patrick Durand,Alwyn Hart,Georges Hofman,Brian H. Jacobsen,S. T. J. Lalor,J.P. Lesschen,Bernhard Osterburg,Karl G. Richards,A.-K. Techen,Françoise Vertès,J. Webb,W. J. Willems +15 more
TL;DR: In this article, the authors compared the implementation of the Nitrates Directive (NiD) and its environmental impacts for member states in the northwest of the European Union (Ireland, United Kingdom, Denmark, Ireland, the Netherlands, Belgium, Northern France and Germany).
Journal ArticleDOI

Mohammad M. R. Jahangir,Mohammad M. R. Jahangir,M. I. Khalil,M. I. Khalil,Paul Johnston,Laura M. Cardenas,D. J. Hatch,Mark Butler,Maria Barrett,Vincent O'Flaherty,Karl G. Richards +10 more
TL;DR: In this article, the potential denitrification rates and ratios of N2O/(N2O+N2) were investigated in intact soil cores collected from 0.30m depths representing A, B and C soil horizons, respectively from three randomly selected locations within a single intensively managed grazed grassland plot in south eastern Ireland.
Journal ArticleDOI
Reducing nitrous oxide emissions by changing N fertiliser use from calcium ammonium nitrate (CAN) to urea based formulations.
Mary Harty,Patrick J. Forrestal,Catherine J. Watson,K.L. McGeough,Rachael Carolan,C. Elliot,Dominika Krol,R. J. Laughlin,Karl G. Richards,Gary Lanigan +9 more
TL;DR: Switching from CAN to stabilised urea formulations was found to be an effective strategy to reduce N2O emissions, particularly in wet, temperate grassland.
Journal ArticleDOI
Microbial Contamination of Fresh Produce: What, Where, and How?
Bernardino Machado-Moreira,Bernardino Machado-Moreira,Karl G. Richards,Fiona Brennan,Florence Abram,Catherine M. Burgess +5 more
TL;DR: There is a critical need for standardized datasets regarding all aspects of disease outbreaks, including how foodstuffs are contaminated with pathogenic microorganisms, to allow food business operators to implement better strategies to improve safety and quality of fresh produce.
Journal ArticleDOI
Modelling soil phosphorus decline: Expectations of Water Framework Directive policies
TL;DR: In this paper, the authors used soil plot data from eight common soil associations to develop a model of Soil Test P (STP) (Morgan's extract) decline following periods of zero P amendment.
