Wild Bee Sunflower Nectar Preferences with Dr. Jarrad Prasifka
Field, Lab, Earth
“Wild bee visitation unaffected by disparate nectar phenotypes in a sunflower inbred line population” with Dr. Jarrad Prasifka. Bees are important pollinators for sunflowers. But, just like humans, they also have preferences, which means it’s important for sunflower breeders to breed the kinds of sunflowers that bees like best. In this episode, Dr. Jarrad Prasifka joins me to discuss sunflower nectar and how much it affects wild bee preferences for sunflower lines. Tune in to learn: · How sunflower lines are bred ...

Living Mulches in Organic Corn with Ben Brockmueller
Field, Lab, Earth
“Mechanical management strategies improve corn production in organically managed living mulch systems” 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. Tune in to learn: ...

Sorgoleone with Drs. Sakiko Okumoto, Bill Rooney, and Guntur Subbarao
Field, Lab, Earth
“Synthesis, function, and genetic variation of sorgoleone, the major biological nitrification inhibitor in sorghum” 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...

Connections, January 2026 with Drs. Wade Thomason, Felix Fritschi, and Aaron Daigh
Field, Lab, Earth
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! Contact us at or on Twitter @FieldLabEarth if...

Rescuing Potato from Buckwheat Volunteers with Dr. Andrew McKenzie-Gopsill
Field, Lab, Earth
“The critical period of cover crop management: A framework for maximizing biomass potential and minimizing volunteers with buckwheat” with Dr. Andrew McKenzie-Gopsill Buckwheat can be a powerful driver of ecosystem services in potato rotations grown in Canada, but with its long-lived seeds and ability to make a whole lot of them in a short time, it can also pose a serious volunteer problem. In this episode, Andrew joins me to discuss how creating a framework to reduce volunteers can help keep this helpful plant from turning into a fearsome weed. Tune in to learn: ...

Optimizing Genomic Selection in Strawberry with Dr. Joshua Sleper
Field, Lab, Earth
“Within-family genomic selection in strawberry: optimization of marker density, trial design, and training set composition” with Dr. Joshua Sleper If plant breeding were a poker game, you’d have to play a lot of hands to beat the house. Quantitative genetics hopes to give players an advantage by recognizing patterns that can point to future success. In strawberry, a genetically complex and labor-intensive plant, this is particularly important. This episode, Joshua join me to discuss his work using quantitative genetics to help give strawberry breeders a hand. Tune in to learn: ...

Giant Ragweed Suppression with Guilherme Chudzik and Dr. Rodrigo Werle
Field, Lab, Earth
“Cereal Rye Biomass Effects on Giant Ragweed Suppression Inform Management Decisions” with Guilherme Chudzik and Rodrigo Werle. For farmers in the Midwest, giant ragweed can be a giant problem. In Wisconsin, where long emergence windows, aggressive growth, herbicide resistance, and power-packed seeds make suppression difficult, farmers are always looking for more hammers to hit this nasty nail on the head. In this episode, Guilherme and Rodrigo join me to discuss their work investigating cereal rye as an additional tool in this long-running fight. Tune in to learn: ...

Genomic Selection with Dr. Jianming Yu
Field, Lab, Earth
“Genomic Selection: Essence, Applications, and Prospects” with Dr. Jianming Yu Genomic Selection is a plant breeding innovation that aims to speed plant breeding by using predictions from a training model enabled by genomics and statistics to guide the breeding decisions. With around thirty years of history around this innovation, it was about time to develop a review on it. Enter Dr. Jianming Yu and his team of coauthors. This episode, we skate the surface of a topic that could go down for miles, covering key areas of genomic selection, what it is, how to use it, and where we can aim to...
info_outline“Microarthropods improve oat nutritional quality and mediate fertilizer effects on soil biological activity” with Dr. Ashley Jernigan
Microarthropods are little critters that can have a big impact on crop production, particularly when it comes to nutrient cycling and nutrient acquisition. However, there’s still much to learn about how the work these little helpers do is affected when paired with different types of fertilizers. In this episode, Dr. Jernigan joins me to discuss how microarthropods get along with different fertilizer treatments.
Tune in to learn:
· What other animal springtails look like
· How researchers count microarthropods
· What impacts organic fertilizers have on microarthropods
· How microarthropods can help crops thrive
