To evaluate the grain yield and economic benefit of soil amelioration and controlled traffic practices on a broader range of soil types across the grain growing region of WA.
The treatments applied in this demonstration are to alleviate multiple soil constraints, including non-wetting, subsoil water infiltration, subsoil acidity and compaction. Prior to the commencement of this trial in 2018, the soil had never been deep ripped. The results of the trial currently indicate that the four different soil amelioration methods do not impact on the grain yield or quality of the cereal crops grown.
