10. Trees and Soils

 Postponed - 50th Anniversary Symposium Wed/Thu 1-2 Sep 

Due to the current Covid-19 lockdown, unknown timing of alert level changes, and because we would prefer a face-to-face celebration of 50 years of the Society, the Agronomy Society Council took the decision on 25 Aug to postpone the 50th Anniversary symposium scheduled for next week (Wednesday/Thursday 1-2 Sep). 

The Symposium will be postponed until April 2022 (dates to be confirmed shortly).  A message will be sent out to sponsors, registrants & members on Thu 26 Aug.

Immediately below are PDF files of individual papers from the Agronomy Society of New Zealand Special Publication No. 10 published in 1995 from the Proceedings of the Trees and Soil Workshop held at Lincoln University, Canterbury on 28 February to 2 March 1994.
