During eleven years at Cranfield University he has been involved in soil research from the nano (zero-valent iron: Pawlett et al 2012) to landscape (Corstanje et al 2008) scale. His research interests include: sustainable management of soil biological systems (farms, horticultural, grass-turfs), environmental impact of nanoparticles, and effects of using organic fertilisers (such as biosolids, organo-mineral fertilisers, and anaerobic digestates) on soil functioning in terms of nutrient cycling, soil health, crop production and turf-grass health. He has gained experimental research in the laboratory, greenhouse and field-scales and is currently supervising two full-time PhD students and one part-time MSc by research.
Current research projects:
- Anaerobic Digestate Application onto Sport Turfs (WRAP)-Co-investigator with a focus on delivering the field-trial component
- Wastes and Organic Matter improve Soil Structure (HGCA)-Co-investigator
- Noordenveld Heathland Restoration, University of Groningen, Netherlands. Co-investigator
- Soil Resilience (BBSRC)-Co-investigator
