Living Mulches in Organic Corn with Ben Brockmueller
Organic farming is a rich and rewarding challenge for farmers, but without the use of herbicides and other conventional methods, weed suppression can be a problem. Cover crops functioning as living mulches can be one way to overcome this challenge, but what works in one crop may not necessarily work in another. In this episode, Ben joins me to discuss cover crop management in corn as a means of weed suppression.

Sorgoleone with Drs. Sakiko Okumoto, Bill Rooney, and Guntur Subbarao
When we fertilize our crops, some of the nitrogen from that fertilizer gets converted into different forms through processes called nitrification and denitrification. When non-plant available forms of nitrogen exit the soil through water or as gas, it's a serious environmental problem. Thankfully, plants have some pretty nifty ways to prevent nitrification, such as biological nitrification inhibition or BNI, a process that manages the bacteria that cause nitrification. In this episode, Sakiko, Bill, and Guntur join me to discuss sorgoleone, a product of sorghum roots that plays a key role in the BNI process.

Connections, January 2026 with Drs. Wade Thomason, Felix Fritschi, and Aaron Daigh
We’re trying something a little bit different. In addition to our regular episodes with Abby, we’ll be adding a monthly bonus episode with Jim Cudahy, the CEO of the Societies. In this first episode, Jim has a chat with the three Society presidents, discussing current challenges and opportunities for the Societies, including ways that members can get the most out of our programs, but guests will vary a lot from there! Please give a listen and let us know what you think. If there are specific guests or topics you want us to cover, let us know!
