Demonstrating the Benefits of Soil Amelioration ("Ripper  Gauge") locations
Aims

To evaluate and demonstrate the benefit of soil amelioration and controlled traffic farming. To evaluate differences in deep ripping timing over subsequent years.

Key messages

• Deep ripping can provide a significant yield benefit which can last for several years. • Deep ripping does not always provide statistical or economic yield benefit immediately. • Subsoil nutrient recovery and redistribution following deep ripping can be significant and should be considered when planning fertiliser applications. • Controlled traffic can prolong the effect of deep ripping on subsoil strength (compaction).

Acknowledgments

 This project (WMG1803-002SAX) is a GRDC investment that is led by the West Midlands Group and this site is managed by the Liebe Group. This site is one of four trial sites across the Wheatbelt that has investigated the use of early post-emergent (EPE) deep ripping on grain yield. Thank you to the Hirsch family for hosting the trial site.
