Living Mulches in Organic Corn with Ben Brockmueller 20.03.2026 38min

"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.

Sorgoleone with Drs. Sakiko Okumoto, Bill Rooney, and Guntur Subbarao 20.02.2026 51min

"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 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. Tune in to learn: · What sorgoleone is · How it helps · What challenges breeders face in increasing it · What challenges researchers face in moving this research out into farms If you would like more information about this topic, this episode's paper is available here: https://doi.org/10.1002/csc2.70066 This paper is always freely available.

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 go in the future. Tune in to learn: · How genomic selection was developed · Why genomic selection should be seen as an innovation in rather than alternative to plant breeding · Why growing out crosses still matters · How AI could be integrated to further genomic selection If you would like more information about this topic, this episode's paper is available here: https://doi.org/10.1002/tpg2.70053 This paper is always freely available.

Precision Turfgrass Management with Dr. Briana Wyatt and Dallas Williams 16.05.2025 34min

"Using electromagnetic induction to inform precision turfgrass management strategies in sand-capped golf course fairways" with Dr. Briana Wyatt and Dallas Williams Golf courses are well known for their beautiful greens, but overusing fertilizer and water to keep them looking pristine can lead to inefficient, expensive, and environmentally damaging waste. Precision turfgrass management can help, but only if we can find the right methods to put it into use. In this episode, Briana and Dallas join me to discuss their research on how electrical conductivity can be used to help determine golf course needs. Tune in to learn: · How many management zones might be in a fairway · How turfgrass type can effect electromagnetic induction correlations · Which properties are most correlated with electromagnetic induction readings · How researchers can get readings on large areas of a golf course fairway If you would like more information about this topic, this episode's paper is available here: https://doi.org/10.1002/agg2.70020 This paper is always freely available.
