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. |

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). |
