Agnes Chepkorir
Project Title: Quantification of nitrous oxide emissions associated with cover cropping and organic manure management activities
Biography Agnes Chepkorir is a Walsh PhD scholar and researcher in Botany at Trinity College Dublin, carrying out her research at Teagasc Johnstown Castle, Wexford. Her research focuses on understanding nitrous oxide (N₂O) emissions from soils and how these emissions are affected by cover crops and organic manures, including slurry and crop residues. Nitrous oxide is a powerful greenhouse gas, and agriculture is a major source of these emissions. Agnes’s research aims to improve understanding of when and why N₂O emissions occur following the application of organic materials and the use of cover crops. The findings will help identify practices to reduce greenhouse gas emissions and nitrogen losses while supporting sustainable agriculture. This work contributes to reducing the environmental impact of farming and helping Ireland meet its climate targets. Agnes has experience in soil fertility management, biological nitrogen fixation, organic amendments and sustainable crop production. She has experience in field experimentation, soil and plant sampling, and data analysis using R. She has gained hands-on experience using static chambers for greenhouse gas measurements and is developing her skills through her PhD research. Originally from Kenya, Agnes is passionate about agricultural research and its role in improving food production while protecting the environment.
