Recorded 2/12/24Certain weeds seem to be tough to control no matter what we do, and for many row crop farms in Pennsylvania, pokeweed and burcucumber certainly fit this description. If you’re struggling to manage one, or both, of these weeds, then this episode will give you some valuable management recommendations on how to get these nuisances under control. We are joined again by one of our resident weed control experts, Mr. Dwight Lingenfelter, who helps shed light on how to alter herbicide...
Recorded: 2/5/24Many farmers have expressed interest in trying to grow hemp in recent years, but understanding the agronomics of producing this crop is essential. In this episode, Dr. David Suchoff joins us to discuss the many aspects of what it takes to grow a successful hemp crop for fiber. We get into his research experience, new possibilities, obstacles, and how to go about growing hemp for the first time.

Recorded: 1/19/2024When it comes to fertilizer, we often discuss things like urea, potash, MAP, and DAP. However, a whole world of organic fertilizer sources exists outside of the traditional inorganic fertilizers most large-row crop producers are accustomed to using. In this episode, we are joined by two very knowledgeable members of our Penn State team to go over the benefits and drawbacks of organic fertilizers. We also discuss how folks interested in organic production might go about maki...
Recorded: 1/5/2024I was once asked a question about whether fungicidal seed treatments negatively impacted beneficial soil fungi. While researching this question, I came across the work of Dr. Jim Germida from the University of Saskatchewan. In this episode, we get into a broad-ranging conversation about the many aspects of soil microbiology with a true expert. This is a valuable conversation for anyone looking to learn more about what’s happening below the soil in their fields! Links:James J...
Recorded: 12/19/23In this episode we are joined by Dr. Glen Harris from UGA to discuss how, when, and why to apply foliar fertilizers. If you think your crop may be deficient in a key nutrient, a proper foliar fertilizer application can remediate the deficiency and help to achieve higher yields. If you’ve ever considered a foliar fertilizer application, this episode will help give you some great foundational knowledge. Links:Plant Tissue (Total) AnalysisFoliar ApplicationGlendon HarrisH...
Recorded: 11/30/23In this episode, we are joined by two very knowledgeable researchers from UC Davis to discuss the effects fertilizer can have on soil microbial populations. Often, we are told that mineral fertilizers are deleterious to soil microbes, but you might be surprised to find that it’s not quite that simple! In addition to fertilizer impacts, we also discuss the effects of tillage practices, organic matter levels, and how microbes behave in agricultural field settings versus more n...
Recorded: 11/13/23Senior agronomist Kevin Fry shares his take on the 2023 growing season in this episode. Everything from the spring drought and Candian wildfire smoke to soybean white mold and weed escapes in corn were covered in the show. Join us to reflect on the 2023 growing season to help you better prepare for the year ahead! Host: Joseph Akins, Penn State ExtensionGuest: Kevin Fry, Pioneer Follow us on Facebook!
Recorded: 11/6/23Tune in as tackle the management of winter wheat from two perspectives, general agronomics and soil fertility. From planting dates and seeding rates to nitrogen applications in fall and spring, we go over all the basics of successfully growing a crop of winter wheat.
