Sandy soils in low and medium rainfall areas
Farmer Co-operator: Mark Siviour and family. Spader: University of South Australia, Roger Groocock. This work is funded under the GRDC project “Increasing production on Sandy Soils in low and medium rainfall areas of the Southern region” (CSP00203); a collaboration between the CSIRO, the University of South Australia, the SA state government through Primary Industries and Regions SA, Mallee Sustainable Farming Inc. and AgGrow Agronomy.
|Other trial partners||University of South Australia, the SA state government through Primary Industries and Regions SA, Mallee Sustainable Farming Inc. and AgGrow Agronomy.|
|Sow rate or Target density||60 kg/ha Razor CL at 25.4 cm row spacing|
The site is located on a broad sand dune running WNW-ESE at Murlong on eastern Eyre Peninsula. The trial comprises 11 treatments x 4 replicates and compares an unmodified control to spading or ripping with inclusion plates (IP) to two depths (30 cm and 41 cm) with and without the addition of high rates of mineral fertiliser or lucerne pellets.
60 kg/ha Razor CL at 25.4 cm row spacing + DAP @ 60 kg/ha (all treatments) + banded Urea @ 81 kg/ha (on non OM and nutrient package treatments only).
RainDrover wetter with the seed @ 2 L/ha.
|Sow date||20 June 2018|
|Harvest date||3 December 2018|
|Plot size||25m x 2.3m|
N 167, P 14, K 105, S 12, Cu 0.03, Zn 17, Mn 0.18 kg/ha. NPKS applied as granular and trace elements as fluids
Treatments applied evenly across the surface on spaded plots or in bands to correspond with ripper tyne spacings, immediately prior to spading and ripping.
DAP @ 60 kg/ha (all treatments) + banded Urea @ 81 kg/ha (on non OM and nutrient package treatments only).
20 June: Triflurex @ 1.5 L/ha, Roundup Weedmaster (540 g ai) @ 2.5 L/ha, Nail @ 80 ml/ha, LI700 @ 300 ml/ha
12 August: Agrityne 750 @ 1.5 L/ha, Zn 2 L, Cu @ 1 L and Mn @ 3 L/ha
