Current applications of my work include (1) promoting carbon sequestration in agricultural systems and understanding the factors regulating carbon cycling and greenhouse gas emissions, (2) developing ways to improve nutrient use efficiency in cropping systems with specific focus on nitrogen and phosphorus, (3) nutrient dynamics in polar (Arctic and Antarctic ecosystems), (4) devising strategies for the effective reuse of wastes for land restoration and remediation (heavy metals and organic pollutants), (5) soil microbial diversity and ecosystem functioning, (6) modelling nutrients dynamics in the plant-soil-microbial and freshwater ecosystems, (7) understanding the barriers to technology adoption by farmers, and (8) the impact of flooding, drought and ozone on ecosystem functioning (including tipping points) and potential strategies to enhance ecosystem resilience.
He has published more than 375 scientific journal articles (H-index = 61; 14,700 citations) and has advised government on both their waste and climate change policies. His research is mainly funded via NERC, BBSRC, Welsh Government, Defra and the European Union.
