Impact of contrasting fertilizer technologies on N dynamics from subsurface bands of 'pure' or blended fertilizer applications

Autor: C. K. Janke, M. J. Bell

Publikováno v: SOIL, Vol 9, Pp 243-259 (2023)

Enhanced efficiency fertilizer (EEF) technologies that employ product coatings to delay nitrogen (N) release or are chemically stabilized to inhibit key steps of N transformations in soil offer potential for improving N use efficiency (NUE) in agricu

Agricultural soils: a sink or source of methane across the British Isles?

Autor: Dominika Krol, Daniela Famulari, P.R. Hargreaves, Ute Skiba, Stephanie K. Jones, Nicola Hinton, M. J. Bell, Juliette Maire, Rachael Murphy, Joanna M. Cloy, Margaret Anderson, Peter Levy, Alison Carswell, Julia Drewer, Nicholas Cowan, Philip E. Stack

This study summarizes a large diverse dataset of methane (CH4) fluxes measured from agricultural sites across the British Isles. A total of 53,976 manual static chamber measurements from 27 different sites were investigated to determine the magnitude

Towards Country-Specific Nitrous Oxide Emission Factors for Manures Applied to Arable and Grassland Soils in the UK

Autor: Laura M. Cardenas, Cairistiona F.E. Topp, Tom Misselbrook, Joanna M. Cloy, Robert M. Rees, John R. Williams, F. A. Nicholson, Rachel E. Thorman, M. J. Bell, David R. Chadwick, Cathy J. Watson

Publikováno v: Frontiers in Sustainable Food Systems, Vol 4 (2020)

Nitrous oxide (N2O) emission factors (EFs) were calculated from measurements of emissions from livestock manures applied to UK arable crops and grassland as part of a wider research programme to reduce uncertainty in the UK national agricultural N2O

Agricultural soils are the primary source of nitrous oxide emissions due to management practices including fertiliser application. While fertiliser rates are one of the main drivers of nitrous oxide emissions, emissions are also dependent on other va

Nitrous oxide emissions from fertilised UK arable soils: Fluxes, emission factors and mitigation

Autor: Cairistiona F.E. Topp, Colin P. Webster, David R. Chadwick, N. J. Hinton, Andrew P. Whitmore, Laura M. Cardenas, H. Balshaw, R. W. Ashton, Joanna M. Cloy, F. Paine, Tony Scott, M. J. Bell, John R. Williams, Robert M. Rees, Keith Goulding

Cultivated agricultural soils are the largest anthropogenic source of nitrous oxide (N2O), a greenhouse gas approx. 298 times stronger than carbon dioxide. As agricultural land covers 40–50% of the earth’s surface agricultural N2O emissions could

A generic model of growth, energy metabolism, and body composition for cattle and sheep1

Autor: I. R. Johnson, J. France, J. H. M. Thornley, M. J. Bell, R. J. Eckard

Publikováno v: Journal of Animal Science. 90:4741-4751

A generic daily time-step model of animal growth and metabolism for cattle and sheep is described. It includes total BW as well as protein, water, and fat components, and also energy components associated with the growth of protein and fat, and activ

Publikováno v: Nutrient Cycling in Agroecosystems. 92:161-181

The global warming potential of nitrous oxide (N2O) and its long atmospheric lifetime mean its presence in the atmosphere is of major concern, and that methods are required to measure and reduce emissions. Large spatial and temporal variations means,
