Abstract
This symposium on 'Boron in Soils and Plants' completes a quartet of reviews of the behaviour in soils and plants of four trace elements, copper, manganese, zinc and boron, selected for their importance in agriculture. The series had its genesis in a suggestion from Professor Robin Graham of the Waite Agricultural Research Institute that it would be appropriate in 1981 to celebrate the Golden Jubilee of the publication in 1931 of the first definitive evidence for the essentiality of copper in plants. The previous decade had seen a resurgence of interest in copper deficiency and toxicity in agriculture and an expansion of our understanding of the behaviour of copper in soils and plants. We therefore decided to promote a review of our understanding of the behaviour of copper in soils and plants by inviting appropriate authors to prepare reviews of 14 topics for publication in a book and presentation at a Golden Jubilee International Symposium on 'Copper in Soils and Plants'. Posters of current research were also displayed and published. Murdoch University, Perth, Western Australia was chosen as the venue because of its then current research on copper, the importance of copper in Western Australian agriculture, and the presence in Perth of many international nutritionists due to the fortuitous scheduling in 1981 of the 'Fourth International Symposium on Trace Element Metabolism in Man and Animals'.
