Diatomaceous earth and palagonite are naturally occurring mined minerals that have value as soil amendments and novel trace-element fertilisers for horticulture, agronomy or organic farming operations. These minerals can increase water holding of soils and/or supply trace minerals to crops. These studies will involve either one or both of the minerals. You'll determine the effect of the minerals on physical and chemical properties and crop growth either in pot trials or field trials. This project will suit you if you're interested in production horticulture, agronomy, plant nutrition or soil science.

Location: St Lucia and Gatton

Expected outcomes: in-depth understanding of plant nutrition, design and implementation of trial

Supervisors: Dr Ryo Fujinuma, Dr Bernhard Wehr
