Producer's Comments

Pros

Cons

  • Low disturbance method of warming and drying soil ahead of planter.
  • Reduced horsepower/fuel/labour compared to conventional tillage.
  • Maintains a high amount of residue.
  • High operation speeds (increased acres/hr).
  • Has allowed us to move to “no-till” corn.
  • Soil remains level for easier traveling when spreading fertilizer or applying herbicides.
  • In dry weather, soil can get hard which can make it difficult for RTS to penetrate.
  • Must be careful under wet conditions – RTS looks like it’s doing a good job but you may actually be causing some soil structure damage.
  • Must have starter nitrogen on planter.
