Contract notice CN4219206 · Grains Research and Development Corporation
Retained stubble can tie up early-season nitrogen as soil microbes break down residues, reducing availability for crop emergence and early growth. While traditional burning methods effectively remove residues, they are increasingly unpopular due to environmental concerns, social license issues, and the associated risks of erosion and nutrient loss. Stubble retention systems require robust research evaluating mechanical and chemical strategies—individually or combined— to improve trash flow at seeding, enhance weed control, and reduce disease risks.
