This seminar series showcases the excellent science our members, affiliates and collaborators are undertaking across the agriculture, food and wine sectors. Expand your network and find new collaborators!

Everyone is welcome – seminars are generally scheduled at 12pm on Thursdays, with some exceptions. Registration is required.

Dr Murray Unkovich  – Why and how do rainfed crops on sandy soils respond to deep tillage? 

School of Ag, Food and Wine

WHEN: Thursday 24th June 2021, 12pm

Abstract:  Coarse textured (sandy) soils, which by definition have a very ow clay content, represent approximately 30% of cropping soils in low rainfall SE Australia. Opportunities for increasing crop production on these soils are probably substantial because yields appear to be well below water-limited potential. In a number of field studies we have been  exploring crop responses to soil physical conditions. Crop responses to deep ripping on coarse textured soils are variable and may result from a number of possible mechanisms. While much attention has historically been focussed on increased total crop water use, examples of increased water and nutrient uptake being the primary reasons for responses to deep ripping in Australia are quite limited and this may be only one of several important mechanisms which operate. Amongst other possible effects, crop shoot (tillering or branching) responses to root conditions (high soil strength) may play an important role in reducing crop water use efficiency in low-rainfall south-east Australia, independent of the capture of water resources by roots. It is hoped the seminar will provide an opportunity to discuss possible ways to explore crop tillering independent of crop growth.

The seminar will be both face-to-face in Charles Hawker Conference Centre and as a webinar.
