I started my career in 1974 as a research scientist in Agriculture at Rothamsted Agriculture Experimental Station in Harpenden, UK. This evolved into doing a PhD in Soil Science, the first year at Rothamsted and then the three subsequent years, 1975-1978, in the Department of Soil Science and Plant Nutrition at the University of Western Australia, Perth, Australia.
