Kerikeri's Steve McNally could not resist donning a gown, (a little larger perhaps than the one he wore in 1981 as a newly-graduated Bachelor of Agricultural Science) when his son Sam graduated from Waikato University last month as a Doctor of Philosophy.
Sam had previously completed Bachelor and Master's degrees in science, continuing his Master's thesis theme of soil science for his PhD, studying carbon inputs to soils under two pasture types, establishing whether increased root mass could increase soil carbon (which he found some scope for).
Professor Louis Schipper, BSc, MSc, PhD Waikato, whose research interests include long-term changes in soil organic matter in pastures and nitrogen saturation of organic matter, and factors controlling organic matter decomposition, including the role of temperature, described Sam's PhD submission as addressing the contribution of roots of different pasture swards to stable soil organic matter.
Sam, who received funding for his doctoral studies from the NZ Agricultural Greenhouse Gas Research Centre, Dairy NZ and a University of Waikato Doctoral Scholarship, acknowledged the assistance of various academic mentors, the people who assisted him with field and laboratory work and the staff at Scott Farm, in the Waikato, where he completed the trial work.
"While I acknowledge his hard work, and the guidance and assistance of all the people he recognised, I will have to show him the photo I took of him with his up-close viewing of soil structure, soil type etc in a post hole I had dug and explained to him back in 1995, when he was still at primary school," Steve said.
