Demonstrating the benefits of break crops in northern Mallee no-till cropping systems

Agronomic constraints threaten the sustainability of intensive cereal no-till cropping systems. Local research has shown these constraints can be managed by diversifying rotations with break crops, however as this research was conducted at only one site, farmers wanted to know whether the same results would be observed on a commercial scale at a whole of paddock level. In 2014, the Mallee Catchment Management Authority (Mallee CMA) funded a project to compare the impact and profitability of the inclusion of broadleaved break crops in paddock rotations in the Northern Victorian Mallee.

农艺限制因素会威胁集约化谷物免耕种植系统的可持续性。本地已有研究表明，通过在轮作体系中引入间隔作物（break crops）以实现轮作多样化，可缓解此类农艺限制因素。但由于该研究仅在单个试验点开展，农户希望了解在商业规模化的全田块尺度下，是否能够重现相同的试验结果。2014年，马里集水区管理局（Mallee Catchment Management Authority，缩写Mallee CMA）资助了一项研究项目，旨在对比维多利亚州北部马里地区在田块轮作体系中纳入阔叶间隔作物（broadleaved break crops）所产生的影响与经济效益。
