Summary
- 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.
