- The orientation of straw tracers did not significantly affect the straw
displacement.
- A trash-board was found to bury significantly more residue than a
moldboard plow without a trash-board.
- Straw near the shear cut has a larger displacement at the same
conditions with and without a trash-board.
- Straw length, tillage depth, and the use of a trash-board impact the
straw burial.
