Will controlled drainage help maintain a healthy nutrient cycle with extreme weather changes and improve yield and water quality? John McMaine and Anthony Bly are back to talk more about controlled drainage and in this episode they discuss:

-controlled drainage and tiling direction

-how controlled structures help weather the extremes

-how controlled drainage creates opportunity to maintain a healthy nutrient cycle

-potential effects on water quality and yield 

-automated controlled drainage and the future

 

Joining us for this week’s episode is Dr. Jeffrey Strock, a professor at the southwest research and outreach center in Lamberton, Minnesota.

How is controlled drainage a beneficial conservation practice in maintaining the water in your fields?

John McMaine and Anthony Bly introduce Controlled Drainage and discuss the following:

• Nitrate load reduction performance
• How controlled drainage reduces load even if it doesn’t reduce concentration
• Type of fields that control drainage works best on
• Potential for automated controlled drainage
• Ideal land conditions for controlled drainage to act as a cost effective tool

Joining us for this week’s episode is Dr. Matt Helmers, director of the Iowa Nutrient Research Center at Iowa State University and Dr. Jeffrey Strock, a professor at the Southwest Research and Outreach Center.

What are the challenges of a saturated buffer and can they work in other states?

John McMaine and Anthony Bly continue their discussion on saturated buffers by addressing the following:

• What factors can affect the performance,
• how do they compare to other conservation drainage practices,
• partnerships and other states that utilize this practice,
• and overall challenges and benefits of saturated buffers.

Joining us again for this week’s episode is Dr. Jeppe Kjaersgaard with the Minnesota Department of Agriculture.

What is a saturated buffer and how can they be beneficial to farmers?

John McMaine and Anthony Bly discuss saturated buffers this week, including:

• what they are,
• how effective can they treat the water,
• the various advantages of installing a saturated buffer and
• criteria that needs to be met to be able to install a saturated buffer.

This week’s guest speaker is Jeppe Kjaersgaard with the Minnesota Department of Agriculture.

Why are bioreactors unpopular and what can we do to incentivize farmers to put them in?

John McMaine and Anthony Bly discuss bioreactors:

• what they are,
• who can benefit from them,
• why they are important and
• what can be done to increase implementation of this practice.

This week’s guest speakers are Laura Christensen with the Department of Crop Sciences at the University of Illinois, Keegan Kult with the Ag Drainage Management Coalition, and Gary Feyereisen with the United States Department Agriculture Agricultural Research Services.
