- Glyphosate applied in fall 2001
- Site deep-tilled once followed by light cultivation
- Glyphosate applied in spring 2002
- Site deep-tilled twice and rocks removed
Note: A pre-emergent herbicide was not incorporated into the soil at these sites, which led to severe levels of weed competition. It is recommended that a trifluralin-metrabuzin pre-emergent be applied during site preparation.
