Your planter evaluation also should include whether to apply starter or nitrogren with the planter. “If corn on corn is part of your cropping plan, or maybe down the road, odds are good that you could benefit from an at-planting nitrogen boost,” Blunier says.

You should consider these components when choosing a fertilizer application system:

  • Coulters or knives for starter and nitrogen placement.
  • Tank size: Match fertilizer tank size to seed bin capacity to synchronize fills.
  • Pump system: Be aware that ground drive planters that are also running a pump can transfer vibration to your meters.
  • Other attachments: Row cleaners, downforce systems, parallel arms, and other modifications can limit the types of fertilizer systems available. Factor in these add-ons when choosing a fertilizer system.
