Overview

May 2002–ongoing: Lecturer Land Resources Sciences, Senior Research Fellow, School of Land, Crop and Food Sciences; The University of Queensland, Australia

As lecturer of Land Resources Sciences at the University of Queensland, Dr Kirchhof has both led and collaborated on over half a dozen projects, and supervised numerous research staff and students. His research has focussed on:

  • Soil–Water relationships;
  • Conservation Agriculture and Irrigation scheduling
  • Soil erosion
  • Water and Nutrient Balances;
  • Spatial Variability of Soil Properties from Ped to Landscape Scales;
  • Dry-land Salinity Management;
  • Water Recycling
  • Computer Modelling of Water Flow with Special Reference to Variability and assessment of deep drainage
  • Knowledge Management;

2011-15 Course leader: Australia Awards in Africa Dryland Farming/Soil and Water conservation Short Course Awards, UniQuest; Australia and Africa, Dr Kirchhof led the design and delivery of the AusAID-funded Dryland Farming Short Course Award, contracted to UniQuest/UQ-ID through GRM International, which was delivered twice a year in 2011 and 2014.

Countries of work experience: Indonesia, Vietnam, Papua New Guinea, the Philippines, Burkino Faso, Côte d’Ivoire, Djibouti, Ethiopia, Nigeria, Tunisia, Uganda, Kenya, Tunisia, Australia.

Dec 1991–Mar 1996: Research Fellow, Department of Agriculture, The University of Queensland; Brisbane

Jan 1989–Dec 1991: Soil Scientist, CASSIRO Ltd, Wauchope, NSW

Research Interests

  • Soil and Water Management
    Water in the soil environment and landscapes: even though it is usually not considered a nutrient, it can in fact be seen as the most important nutrient. It drives productivity of our ago-ecosystems as well their sustainability. Water must be used efficiently, what can efficient water use achieve? What are the limits of this efficiency?
  • Conservation Agriculture
    Conservation Agriculture (CA) is considered the current best management practice for sustainable and productive ago-ecosystems. Is this correct? - May be not? We need to know more about practical suitability of CA in a range of environments, especially in Africa as wholesale promotion of CA can be detrimental to its adoption potential. The big questions are: is it a management method to satisfy world food demand? Can it be used to mitigate or manage climate change? What are its limitations?
