STUDY DESIGN
Tracked systems for planters have become popular options for attempting to reduce soil compaction in the rows adjacent to the paths of equipment travel. Multiple combinations of these tracked systems were evaluated and the tested variations in equipment set-up can be observed in the table at the right. Planter was filled to 75% with seed.
