Trials and demonstrations involving soil mixing either with a spader or ripping with inclusion plates have been shown to increase yields on sandy soils on Eyre Peninsula (EP). Many of these trials have included the addition of organic material incorporated at rates of 5-10 t/ha. Whilst generally these treatments have provided yield increases for a number of years post application, the rates applied have proven to be uneconomic (EPFS 2019, p 71). This project was originally developed by the Lower Eyre Ag
Development Association (LEADA) with two major objectives being:
1. To test ripping with inclusion plates on a wider range of soils.
2. To trial rates and sources of organic matter that are practical for broadacre use.
Deep ripping with inclusion plates generally resulted in lower plant numbers than unripped plots.
• Yield increases to ripping were observed mainly in sandy and calcareous soils.
• Treatments including the incorporation of mineral nutrients and organic amendments delivered mixed results but were generally the highest yielding treatments
