What is Manure Injection???

Placing manure directly into the soil root zone increases nutrient recovery leading to a reduction in commercial fertilizer costs, reduced crop damage and application costs.

Did you Know? Your local Soil & Water Conservation District offers Cost Share or Tax Credit for manure injection.

  • Cost Share: $45/acre reimbursement
  • Tax Credit: If cost share is not taken, a state tax credit of 25% of out-of-pocket expenses is available
  • Updating your Nutrient Management Plan to reflect manure injection application is required
    • Interested participants are encouraged to contact their NMP planner ASAP regarding updates
  • No-till planting methods are required on all fields receiving manure injection application
  • Participant must provide an invoice that indicates acreage injected, application rates and type of equipment used
  • Requires sign up before injection occurs


Why inject dairy slurry?

  • Doubles the plant available Nitrogen from slurry compared to broadcast application
    • 114 lbs available N injected vs. 50.4 lbs available N broadcast (6Kgal application rate)
    • At 2023 Nitrogen prices, that is nearly a $50/ac. fertilizer cost savings! (~$0.80 x 64lbs)
  • Increases availability of P, K, Ca, Mg, S, Zn by placing nutrients in the root zone
  • Meets no-till criteria by maintaining soil structure
  • Injected manure and starter at planting minimizes crop damage
  • Reduction in odors
  • Returns effective carbon to soil, enhancing soil health
  • Better on-farm nutrient balance, reduce purchased inputs
  • Potentially eliminates the need for sidedress Nitrogen
