Environmental consulting with emphasis on soil science, re-use of treated wastewater, behaviour of heavy metals in soils, as well as teaching a very general course on terrain to 1st year landscape architecture students. I have a website that tells you more: www.vandegraaff-soilshorizons.com.au.My professional training started at Wageningen Agricultural University, The Netherlands, where I obtained a BSc ('56) and MSc degree ('59), and afterwards I was awarded a PhD in soil science from Cornell University, Ithaca, NY ('71). I have worked a lot in developing countries with great pleasure but I am based in Melbourne, Australia. I started off with CSIRO in Canberra in 1959 and after working with various government departments I became self-employed in 1988. It is my goal to remain useful in every aspect of life so long as I can do it, so I am still working almost full-timeSpecialties: Interpretation of soil science for practical purposes, "detective" work on heavy metals in soils; My students at Royal Melbourne Institute of Technology seem pretty pleased with what I bring to them.
