  • Crop residue management is essential for successful direct seeding.  
  • The most practical way to manage crop residue is with the combine.  
  • The residue should be spread uniformly over the entire width of the header cut.
  • Chaff spreading must occur with the combine.  
  • Stubble height should not generally exceed the row spacing, until some experience is gained in different crop conditions on the farm. 
  • Harrowing can spread straw but not chaff. It is better to harrow in the fall before straw settles.  
  • Mowers and shredders have high power requirements, but they produce a more uniform residue cover and can correct a residue problem. 
  • Seeding equipment must have increased residue clearance.  
  • Crop type and variety influence the amount of crop residue.
