Z is for Podzol

“Podzol Soils occur in areas of high rainfall and are usually associated with forest trees with an acid litter. The soils occur mainly in materials from silica-rich rocks. They cover 13% of New Zealand.”

In the Labs for Lincoln Uni’s Level 1 Soil Science course this week we have been looking at different soil profiles, describing horizons and classifying them to the NZ Soil Classification. Podzol is one that the students get to and ponder for a while. It’s abundance of different horizons can be quite confusing at first, but after working through them, can be appreciated as a beautiful.

A Podzol generally has an Ah horizon, followed by a E, then all or one of; Bh, Bs, Bfm, making for a colourful soil description and something to get fresh soil science minds working. The E horizon is an eluviated horizon, where the weathering over thousands of years has leached any nutrients, organic matter, iron and aluminium oxides out of it making it a very pale horizon.

Staff Intro – Senior Lecturer Carol Smith

Main Research Areas: Paleoclimate. Land-reclamation. Pedology.

Carol is originally from the UK, growing up in South-East England, before moving to New Zealand in 1993. She completed a BSc. (Hons) in geographical science at Portsmouth, followed by a MSc in pedology and soil survey at Reading and then a PhD in soil science at Aberdeen.

Paleoclimate – a climate prevalent at a particular time in the geological past.

Pedology – the study of soils in their natural environment. The scientific study of soils and their weathering profiles.

It was her undergraduate focus on geomorphology, pedology, combined with micro-morphology while at Reading, that got her into the area of research she follows today. “The paleoclimate record in soils and landscapes is relevant to our understanding of the extent of past climate change; it offers a point of reference to computer models of future climate”. Carol is also passionate about land rehabilitation and the opportunities that using recycled organic materials can have on improving soil quality.

“Looking at New Zealand’s past climate through soils is very exciting.”

Carol Smith at Soil Judging Comp 2016

Carol started at Lincoln University as a tutor alongside the legendary Phil Tokin in 1993. Following a move to Sydney in 1997 with her young family and a stint in the private sector as an environmental consultant, she returned to Lincoln in 2005 as a lecturer in soil science. She was appointed to her present role as HoD in 2017. Carol’s inspiration in this role is being able to work with people and help them do their job to the best of their ability; whether that is through teaching, research or university management.

“It’s all about the people – the staff and students in the Soil Department; we all work together as a good team. We are small enough to know each other and we also have a few adventures along the way.”

In her down time Carol makes the most of the outdoors, seeking a balance between a busy work week and active relaxation on the weekends, when she can be found hitting the Port Hills on her bike. Skiing and tramping are also favourites when the seasons allow, as well as catching up with her two young adult children (when they’re not asking for money or to borrow the car). “Exploring NZ, all those hidden, beautiful corners.”

PhD Postgrad Intro – Monica Giona Bucci

Monica Giona Bucci has just completed her PhD in the department of Soil Science at Lincoln University. Professor Peter Almond (Lincoln University), Dr. Pilar Villamor (GNS Science), Dr. Martitia Tuttle  (Tuttle & Associates) and Dr. Carol Smith (Lincoln University) have supervised her research.

I come from Italy where I completed a Bachelor and Master degree in Earth and Environmental Sciences at “La Sapienza” University of Rome. During both my final dissertations I learnt the importance of studying pedology and GIS mapping and these skills were particularly useful during my PhD.

My PhD project was about studying the sedimentary architecture of two settings (alluvial and coastal) affected by liquefaction features triggered during the 2010-2011 Canterbury Earthquake Sequence. My PhD research was very interesting because it allowed me to learn different techniques for liquefaction investigations and to contribute in improving the understanding of the susceptibility to liquefaction across the Canterbury Region.

State of the Nation’s Environment 2017

Staff Intro – Professor Leo Condron

Main Research Areas: Phosphorus. Micro-organisms. Chronosequences.

Leo grew up in Glasgow, Scotland. After completing a Bachelor of Science with Honours at the University of Glasgow he moved to New Zealand to further his education at Lincoln University. 1980 – 1984, PhD in Soil Science at Lincoln. Reaching for the highest possible qualification, Leo also completed a Doctor of Science in Soil Science at Canterbury. Returning to Lincoln in 1989 he’s never left, and is now a Professor of Biogeochemistry; 50% research (including PG supervision), 30% teaching, 20% admin.

Why soil science? “My father was a farmer, I always had an interest in Agriculture and while doing my degree I developed a greater interest in soil science.” Working at Lincoln University has allowed for Leo to focus on one area of research for more than 30 years, meaning that he has been able to continue to develop it. ‘It’ being phosphorus, or a combination of all his passions; phosphorus, micro-organisms and chronosquences where possible. This is what keeps him going, having never lost interest in it or agriculture.

Continuity is Leo’s favourite thing about the Soil’s Department at Lincoln. The Lincoln University Soil Science Department has been able to sustain the continuity of research even though there has been a lot of changes, allowing for a coherent department that is great to work in. Maintaining this number of Soil Scientists together has been really lucky, “There is no other group of soil scientists this big in the world that I know of.

Outside of University Leo’s time is taken up being a father to three kids and some tropical fish. Also enjoying music, Cuban cigars and a good bottle of Bourbon whiskey.

Staff Intro – Professor Timothy Clough

Professor Timothy Clough.

Main Research Areas: Green House Gases (GHG), Nitrogen (N) and Carbon (C).

Lincoln University has been lucky enough to have Tim here for 20 years! Tim’s enthusiasm for research and teaching in soil science hasn’t waned, saying “there’s no ground hog days, it’s always different, there’s variety and it’s very interesting. The discovery of new findings keeps me going.”

Tim is a Christchurch man, born and breed in Canterbury. After working on a Sheep station one summer he was inspired to go to Lincoln University, where he pursed a degree in Agricultural Science. Completing a BAgSc with Honours he went to work at MAF in Hamilton, before returning to Lincoln for a PhD in Soil Science. Tim’s PhD research looked at “Bovine Urine N in Peat Soils”, this lead onto nitrous oxide and where he is today, specialising in GHGs.

Tim’s role at Lincoln University includes scientific research, teaching and postgraduate supervision. The things that stand out for Tim about working in Lincoln University Soil Science Department are; the open door policy, collegiality and the expertise within the department. “We’re world leading in some of the work we do. When I came to Lincoln, you’d heard of the guys who worked here, they were well known for what they were achieving on the world stage.”

‘Collegial – an adjective describing a work environment where responsibility and authority is shared equally by colleagues. You know you work in a collegial environment when your co-workers smile at you, and you don’t have to hide from your supervisor.’

When he’s not hard at work at Lincoln University unearthing new scientific discoveries, teaching young minds and supervising postgrads, Tim enjoys the outdoors. Spending his down time; tramping, fishing, swimming and biking, also enjoying his music, having played saxophone. Who knows how he fits it all in!
