It was last landformed in 2012 when cut areas of more than 10 cm were deep ripped and at least 5 cm of topsoil was applied. The deepest cuts were up to 26 cm. The soil was a transitional red brown earth and the paddock historically had low water use. The previous two crops were grazing oats. Single super was applied at a rate of 200 kg/ha to the last oat crop to build up phosphorus in the soil. Fertiliser Both urea and a starter fertiliser were broadcast before spreading the seed. In the fill areas, urea was applied at 250 kg/ha and Rice Energiser at 150 kg/ha; and in the cut areas, urea was applied at 315 kg/ha and Rice Energiser at 225 kg/ha. Liquid zinc fertiliser was applied to the seed (in the auger) immediately before sowing. The grower was unsure if the zinc seed treatment had much effect on the seedling growth but because he has had trouble with establishment in the past, he was willing to apply it at the cost of $3.75/ha. Sowing Reiziq seed was broadcast at 160 kg/ha. The seed and fertiliser were rolled in after spreading. The grower aimed to bury the seed to stop seedling drift in windy conditions and to prevent crop damage by ducks. The number of ridge roller operations depended on the firmness of the seedbed.
