Join soil productivity research officer Giacomo Betti [1] 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 [2] 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.
