Ausplow South Australian dealer Ramsey Bros’ Murray Bridge branch hosted a deep tillage day recently. It was supported by local Elders rep Craig Bell and was held on Peter Rose’s property at Karoonda (east of Murray Bridge). Several of the local farmers have since used the trial unit on their properties and will be monitoring crop progress through the year. In addition to the deep fracturing of the soil, Peter has recently been trialing deep banding trace elements down to 350mm (14in) into an infertile band of soil with very good results. Trials have also been started using inclusion plates on the back of the tines allowing top soil to fall down the slot behind the ripper tine. According to Ausplow sales and marketing manager Chris Blight, there is increasing interest by Eastern States farmers in deep tillage. “There’s a lot more understanding now, based a lot on the yield results achieved by WA farmers over more than three decades,” he said. “The biggest yield increase is on sandy soil but we’re also seeing yield lifts in lights loams. “While a lot of emphasis at the moment is on going deeper, we think a more incremental approach is of more value and less costly. “The plant roots should tell the story about hardpans and compaction issues and that’s generally the best guide as to how deep do you go. “DBS owners are seeing really great changes to their soils over a period of years and soils are holding more moisture while plants roots are contributing to a more structured soil which contributes to crop yield increases.”
