Background and Aims Subsoil constraints are a widespread limitation to agricultural production in southern Australia, reducing rooting depth and access to water and nutrient resources. The addition of organic amendments and gypsum to dispersive soils has been shown to enhance soil structure and crop nutrition, with potential to significantly increase crop yields. The spatial variation of soil types and constraints within paddocks necessitates zone-specific amelioration strategies that are more cost-effective. Methods Intact soil columns were collected from two distinct soil zones of a single paddock to explore the variation in crop response to several traditional and novel ameliorants under controlled conditions. Ameliorants were incorporated at a depth of 15—30 cm, prior to planting wheat ( Triticum aestivum L. cv. Mace). Resulting changes in physicochemical soil properties and yield components were then quantified. Results The performance of amendments on soil properties and plant productivity depended on the soil zone. In Soil Zone 1, combinations of organic amendments and selected biochar products increased root growth into the dispersive subsoil, and increased yields by up to 55% relative to the control. In contrast, although all amendment combinations reduced dispersion in Soil Zone 2, no benefits to crop growth or grain yield were observed. Conclusions These findings highlight that the agronomic effectiveness of soil amelioration depends strongly on underlying soil characteristics. Tailored interventions that account for within-paddock soil variability are essential for maximising crop response and ensuring the economic viability of amelioration in heterogeneous landscapes.
背景和目的底土约束是南澳大利亚农业生产的普遍限制，减少了生根深度和获得水和养分资源。在分散土壤中添加有机改良剂和石膏已被证明可以改善土壤结构和作物营养，并有可能显著提高作物产量。围场内土壤类型和约束的空间变化需要更具成本效益的区域特定改良策略。方法在同一围场的两个不同土壤区收集完整的土壤柱，研究在控制条件下作物对几种传统和新型改良剂的响应变化。在种植小麦（Triticum aestivum L. cv）之前，在15-30 cm的深度加入改良剂。梅斯)。由此产生的土壤理化性质和产量组成的变化随后被量化。结果改良剂对土壤性质和植物生产力的影响与土壤带有关。在土壤1区，有机改良剂和选定的生物炭产品的组合促进了根系向分散的底土生长，相对于对照，产量提高了55%。相比之下，虽然所有改良剂组合都减少了土壤2区的分散，但对作物生长和粮食产量没有任何好处。这些发现表明，土壤改良的农艺效果在很大程度上取决于土壤的潜在特征。考虑到围场内土壤变异性的量身定制的干预措施对于最大限度地提高作物反应和确保异质景观改良的经济可行性至关重要。
