Stubble management to improve crop yield

Over recent seasons adoption of stubble retention has plateaued in the Mallee and some growers are reducing the area of stubble retained until the next growing season. An experiment was undertaken to identify potential improvements in stubble management so this trend could be reversed. The experiment examined how different amounts and types of stubble impact on subsequent water availability and crop yield.

近年来，马尔利（Mallee）地区的作物残茬还田（stubble retention）技术应用已趋于平稳，部分种植户正缩减留存至下一生长季的残茬面积。为探明残茬管理的潜在优化路径以扭转这一趋势，本试验探究了不同用量与类型的作物残茬对后续土壤水分有效性及作物产量的影响。
