Conservation Conversations: Dec. 15

Join us for a Conservation Conversation Dec. 15

You’re invited to learn about conservation practices members have tried through casual conversation on the farm.

2:30-3:30 pm Conservation Conversation on Tuesday, Dec. 15 hosted by Kinnard Farms

Topic: Bark bed bioreactor for safely removing dissolved nutrients and purifying tile line water before it’s discharged.

Details: Meet at Kinnard Farms conference room, N8200 Tamarack Rd., Casco. No RSVP required.

Field Tile line drainage systems  play an integral role in the adoption of conservation cropping practices in the Midwest, and an installation of this type of drainage is often necessary to successfully convert a field from conventional tillage practices to a no till/cover crop system. Sediment and nutrient loss from a farm field can be substantially lowered with a properly installed tile drainage system, but nutrients, especially Nitrogen, can be inadvertently removed from the field under certain weather conditions.

A bark bed bioreactor appears to offer one possible solution to this issue, safely removing dissolved nutrients and purifying tile line water before it is discharged.

Lee Kinnard will share the following:

  • Their reasoning behind the installation of the bioreactor
  • The monitoring system, how it works and how they evaluate and interpret the results
  • Cost per acre for installation
  • Data collected to date
  • Long range plans for monitoring and interpreting this data
  • What they hope to learn from this installation and monitoring
  • Changing agronomic practices based upon data collected
