2015 Manawatu Lecture

Sustaining the productive capacity of our soils

Professor Mike Hedley, Massey University

7.30 pm Thursday, 27 August, Te Manawa – Art Gallery, 326 Main Street, Palmerston North

 2015 is the International Year of Soils, which aims to increase awareness and understanding of the importance of soil for food production and essential ecosystem functions. In this, our seventeenth Manawatu Lecture, Professor Mike Hedley will talk about the work that he and his co-workers are doing here in the Manawatu to sustain the productive capacity of our soils.

Mike Hedley is the Professor in Soil Science at Massey University and the Director of the University’s Fertiliser and Lime Research Centre. Mike’s research is focussed on soil-plant interactions; fertiliser development and evaluation; soil fertility; and nutrient cycling in grazed pasture systems and nutrient budgeting.

The Manawatu Lecture was established by the Royal Society of New Zealand Manawatu Branch as its annual prestigious lecture to recognise aspects of science particularly relevant to the Manawatu.

All warmly welcome

Going super heavy – the end of the periodic table of elements

Distinguished Professor Peter Schwerdtfeger, Massey University

7 pm Thursday, 13 August, PNBHS Speirs Centre, Featherson Street, Palmerston North

The first periodic table of the elements was proposed in 1869. It was compiled by arranging the elements in ascending order of atomic weight, grouped by chemical properties. At that time it was not known how high in atomic weight the elements could go before becoming too unstable and decaying.  But in the last decade we have seen the production of new elements up to nuclear charge 118.  So just how heavy can elements go and what can chemists do with such exotic elements? Where does the periodic table end?

All warmly welcome.
