Join soil productivity research officer Giacomo Betti live on Monday 27 November from 12-12.30pm as he delivers Cost-effectiveness of combinations of clay spreading and strategic tillage for management of repellent soils.
To watch the recorded version of this webinar, vist the Broadacre agronomy webinar series page.
Clay spreading is a proven method for the amelioration of water repellent soils but it requires high initial capital investment and the outcomes can be quite variable.
A field trial at Moora in Western Australia was established in early 2016 on a water repellent sand in order to identify the most cost-effective combination of clay spreading (at 0, 100, 150 and 250t/ha) and subsequent incorporation methods (off-set discs and rotary spader).
The trial will continue to be evaluated for a further three seasons (until 2019) in order to better assess the longevity and cost-effectiveness of all treatments in the medium to long term.
