Personal profile
Research interests
I am a soil scientist and currently involved as a grassland and forage researcher at the SRUC Dairy and Innovation Centre investigating methods to improve grass and forage yields through improved soil health. My current main areas of interest are:
- Maintaining and improving soil quality
- Developing management tools to aid improved soil quality
- Use of precision and novel methods to improve grassland and forage yield through reduction of soil physical damage - Controlled traffic
- Inclusion of legumes as mixtures and in rotations to enhance soil quality and for a more resilient protein source
- Greenhouse gas emissions (N2O, CH4 and CO2) mitigation from grassland and forages
- Use of laser methane detector to monitor emissions from livestock
- Use of multispecies swards for greenhouse gas mitigation and soil health improvement
