Effect of fertiliser sown with wheat seed on Mallee soils

There are major opportunities to improve crop performance on Mallee sands, opportunities to invest in the transformation of poor sands and opportunities to improve yield through more targeted agronomy of sandy soils. In 2015 wheat plant establishment was significantly better on non-wetting sand (crest and dune) plots that received no fertiliser with the seed compared with those that received 50 kg DAP/ha. Similar effects were measured in trials established by Jack Desbiolles at Moorlands in 2015 (McBeath et al. 2016).

在马利（Mallee）砂质土上提升作物表现、投资改良贫瘠砂质土，以及通过针对砂质土的精准农艺技术提高产量，均存在可观的发展机遇。2015年，在未随种子施加种肥的非润湿性砂质土（丘脊与沙丘区域）试验小区中，小麦出苗率显著高于施加50千克/公顷磷酸二铵（DAP）的试验小区。2015年杰克·德比奥利斯（Jack Desbiolles）在穆兰兹（Moorlands）开展的试验中，同样观测到了类似结果（McBeath等，2016）。
