Project Title:Increasing production on sandy soils in the low-medium rainfall areas of the southern region
Peer Review: Therese McBeath (CSIRO)
- Deep ripping reduced soil penetration resistance and resulted in a grain yield increase of 0.85 t/ha.
- Deeper placement of nutrients had no effect on production above the physical impact of ripping.
- Spading nitrogen rich organic matter resulted in a yield increase of 0.6 – 1 t/ha.
- Grain protein was significantly increased where available nitrogen was increased by either fertilisers or organic matter.
- Ground cover was rapidly established following a one pass spade and sow system; however, establishment counts were lower and more variable compared to normal no-till sowing methods.
