Areas of expertise


Guy Kirk joined Cranfield in February 2003. Before that he spent 13 years at the International Rice Research Institute (IRRI) in the Philippines, initially as Soil Chemist and later as Head of the Soil and Water Sciences Division. Prior to IRRI he did doctoral and post-doctoral research in the Soil Science Laboratory, University of Oxford, and between IRRI and Cranfield he was on sabbatical in the Department of Plant Sciences, University of Cambridge. He is a core member of BBSRC Research Committee B, Associate Editor of European Journal of Soil Science, and a Fellow of the Royal Society of Chemistry.

Current activities

 Professor Kirk's research focusses on physical, chemical and biological processes in soils; how to quantify soil properties and functions; and how to model soil systems at scales from the microbial to the continental.

Current/recent projects include:
  • Long-lived radionuclides in the surface environment. Collaboration with Manchester University, Southampton University and others. Funded by NERC
  • Rice germplasm for high grain Zn content and tolerance of Zn deficient soils. Collaboration with IRRI Philippines, JIRCAS Japan, Imperial College London and Southampton University. Funded by BBSRC/Gates Foundation/DfID
  • A field laboratory for measuring whole-soil carbon balances and greenhouse gas fluxes under controlled temperature and moisture. Funded by Royal Society/Wolfson Foundation
  • CarboExtreme - The terrestrial carbon cycle under climate variability and extremes - a pan-European synthesis. Funded by EU-FP7
  • An improved empirical model of soil carbon dynamics in temperate ecosystems. Funded by NERC
  • Comparison of soil carbon changes across England and Wales estimated in the Countryside Survey and the National Soil Inventory. Funded by Defra
  • Calcium carbonate formation in soils. Collaboration with British Geological Survey. Funded by NERC/EPSRC
  • Towards a general method to 'scale up' process models in the arable landscape. Collaboration with Bioinformatics & Biomathematics Division, Rothamsted Research. Funded by BBSRC
  • Modelling integrative behaviour of soil-plant systems: plant uptake of strongly-sorbed solutes. Collaboration with Mathematical Institute, University of Oxford, and School of Environment & Natural Resources, Bangor University. Funded by BBSRC
