Incorporating Lime to depth on duplex Wheatbelt soils

The aim of this trial is to quantify the value of lime applications using different incorporation methods and compare the economic and agronomic returns of each. This trial also includes an application of a rapidly acidifying Elemental Sulphur to demonstrate how soils and crops will perform 10-years into the future if no action is taken to maintain pH levels. The trial also aims to analyse the interactions between each incorporation technique and its effects on ameliorating other crop constraints.The objective is to give growers a greater understanding of different methods of lime incorporation and the most cost-effective practice locally and to extend on these findings with other research being conducted on varying soil types throughout the state, so that growers can make informed decisions for implementing their own liming strategy.

本试验旨在量化不同土壤混入方式下石灰施用的效益，并对比各方式的经济与农艺收益。本试验还增设了速酸化元素硫（Elemental Sulphur）施用处理，用以模拟未来10年内若未采取任何维持土壤pH值的措施时，土壤与作物的生长表现。此外，本试验亦旨在分析各类石灰土壤混入技术之间的交互作用，及其对缓解其他作物生长限制因素的效果。本试验的核心目标是帮助种植户更全面地掌握各类石灰土壤混入方法，以及本地最具成本效益的施用方案；同时结合全州范围内针对不同土壤类型开展的其他相关研究，进一步拓展本次试验的研究结论，助力种植户制定科学合理的自有石灰施用策略。
