How we measure 'reads'
A 'read' is counted each time someone views a publication summary (such as the title, abstract, and list of authors), clicks on a figure, or views or downloads the full-text. Learn more
I am a Postdoctoral Research Officer in Environmental Science based at Bangor University, supervised by Prof Davey Jones and Prof Dave Chadwick. My PhD research investigated the environmental and agronomic benefits of multispecies leys, examining livestock productivity (e.g. liveweight gain), greenhouse gas emissions (e.g. nitrous oxide emissions), livestock excreta composition, urine-patch ammonia (NH3) volatilisation, forage quality, soil biochemistry, and soil structure (using X-ray CT).

- Research Support Technician / PhD student
- I was previously a PhD researcher and Research Support Technician on the BBSRC-SARIC funded "Restoring soil quality through re-integration of leys and sheep into arable rotations" project, led by Prof Jonathan Leake at Sheffield University. My role at Bangor is linked to my PhD project and includes greenhouse gas measurements and analysis, soil chemical analysis, livestock excreta composition analysis, livestock productivity and health measurements, and forage quality and yield analysis.

Agriculture is essential for providing food and maintaining food security while concurrently delivering multiple other ecosystem services. However, agricultural systems are generally a net source of greenhouse gases and ammonia. They, therefore, need to substantively contribute to climate change mitigation and net zero ambitions. It is widely ackno...
Agricultural intensification and the subsequent decline of mixed farming systems has led to an increase in continuous cropping with only a few fallow or break years, undermining global soil health. Arable-ley rotations incorporating temporary pastures (leys) lasting 1–4 years may alleviate soil degradation by building soil fertility and improving s...
The leaching of base cations in acidic soils can result in calcium (Ca²⁺) and magnesium (Mg²⁺) deficiencies, which are important for microbial cell function. We aimed to determine if microbial carbon use efficiency (CUE) and microbial biomass carbon (MBC) were limited in acidic soils due to a lack of base cations. Microbial CUE across a range of ag...
Ongoing specialization of crop and livestock systems provides socioeconomic benefits to the farmer but has led to greater externalization of environmental costs when compared to mixed farming systems. Better integration of crop and livestock systems offers great potential to rebalance the economic and environmental trade-offs in both systems. The a...
The microbial partitioning of organic carbon (C) into either anabolic (i.e. growth) or catabolic (i.e. respiration) metabolic pathways represents a key process regulating the amount of added C that is retained in soil. The factors regulating C use efficiency (CUE) in agricultural soils, however, remain poorly understood. The aim of this study was t...
