How important is straw for yield of no-till crops on heavy soils in the low rainfall southern Mallee?

To test if no-till crops grown on clay soils in the low rainfall, southern Mallee environment would yield better if more straw could be retained on the soil surface from the previous crop.

本研究旨在验证：在低降水的南部马尔利（Mallee）区域的黏质土壤上种植免耕作物（no-till crops）时，若保留更多前茬作物秸秆覆盖于土壤表面，是否可提升作物产量。
