“Soil degradation and crop yield declines persist 5 years after pipeline installations” with Theresa Brehm.
Underground pipeline installations are crucial for energy supply, helping to meet rising demand. However, these installations can significantly impact agricultural lands due to soil excavation, heavy machinery use, and resulting soil disturbances. Although companies typically offer support to farmers for up to five years, claiming that soil health and productivity are restored within that period, many farmers report ongoing issues with soil degradation and reduced crop yields. This highlights the need to evaluate the true impact of pipeline installations on soil health and crop productivity and to assess the effectiveness of remediation efforts in restoring soil vitality. In this episode, Theresa Brehm shares insights from her research on assessing the impacts of pipeline installations on soil health and agricultural productivity in Ohio state, along with insights from farmers' experiences.
Tune in to learn:
· What are the impacts of underground pipeline installations on soil health and crop productivity?
· How are farmers compensated for their losses?
· How do pipeline installations affect soil texture, porosity, and crop yields?
· How effective are company-led land remediation efforts in restoring soil health and productivity?
· What are the long-term challenges of restoring soil health after pipeline installations?

Bioenergy crops present a promising source for biofuel production, offering a potential solution to reduce reliance on fossil fuels. However, they face criticism for potentially encroaching on arable land essential for food production to sustain growing populations. To address this issue, there is a growing focus on utilizing marginal lands for growing bioenergy crops, which are less suitable for crop production. Marginal lands typically suffer from poor soil health and low nutrient and water availability. Therefore, it is crucial to identify and develop bioenergy crops that can thrive in such conditions and produce biomass for biofuel production while also confirming which marginal lands are best suited to these uses. In this episode, Dileepa Jayawardena, a Research Associate at The Great Lakes Bioenergy Research Center, Michigan State University, sheds light on his research aimed at finding suitable bioenergy cropping systems for marginal lands in Michigan and Wisconsin for producing biomass for long-term bioenergy production while minimizing the competition of land for food crops.

· What are bioenergy crops?
· What is the importance of bioenergy crops?
· Why marginal lands can be suitable for bioenergy crops?
· Which cropping system is better for marginal lands?
· How to make sustainable biofuel production?

“Recalibrating the Pennsylvania pre-sidedress soil nitrate test recommendations for modern corn production” with Charles White.
Nitrogen management is one of the most important agronomic practices in modern crop production systems. The Pre-Sidedress Soil Nitrate Test, also known as the PSNT, gives farmers an estimation of plant available nitrogen in the soil, allowing them to calculate how much nitrogen the plants still need. The existing PSNT method was developed during the 1990’s. Now, farming practices are improved, altering the amount of nitrogen fertilizer plants need. Thus, it is important to re-calibrate the test so farmers can have a more accurate estimation of nitrogen requirements and reduce the cost of production. In this episode, Dr. Charlie White shares his insights on re-calibrating the pre-side dress soil nitrate test for modern corn production systems.
Tune in to learn more about:
· What the Pre-Sidedress Soil Nitrate Test does
· The importance of Nitrogen mineralization
· Which improved practices have impacted the test’s accuracy
· Which factors most impact the test results now

“Nitrogen mitigation scenarios to reduce coastal eutrophication” with Wafa and Patrick.
Eutrophication is a state of overgrowth of aquatic plants, such as algae and seaweeds, in water bodies due to the excessive pouring of nutrients from different sources like agriculture, industry, and human settlements, causing disturbances to the ecosystems. Coastal eutrophication is a major issue worldwide due to the increasing discharge of nutrient emissions from agricultural activities into coastal ecosystems. Several efforts have been made to reduce eutrophication, achieving up to 35–40% reduction, but these measures are not sufficient to eliminate the problem. For more sustainable and effective solutions, the root causes of the nutrient emissions, especially nitrogen, need to be addressed in current agricultural practices. In this episode, Drs. Wafa Malik and Patrick Durand share their research on the reduction of coastal eutrophication in Brittany, France, focusing on changing cropping systems and reducing the sources through modeling the effectiveness of different approaches and taking into consideration the interests of farmers and the local community.
Tune in to learn more about
· How eutrophication happens
· What are the causes and consequences of coastal eutrophication
· What are the agricultural impacts of eutrophication
· How we can change cropping systems to reduce eutrophication
· What mitigation challenges exist in reducing coastal eutrophication

“Focusing the GWAS Lens on days to flower using latent variable phenotypes derived from global multienvironment trials” with Sandesh Neupane and Derek Wright.
Lentil, a pivotal pulse crop, is recognized as an important part of food and nutrition security in the world. It has rich sources of important nutrients, is easy to cook, and thrives well on the farm. Due to its rich dietary benefits, lentil has been introduced to North America, especially in Canada. Originating as a warmer climate crop, domesticated in the Middle East and North Africa, and widely adopted in Southeast Asia, lentil can face adaptation issues in the cooler Canadian climate. This struggle directly impacts flowering, pod-bearing, and overall yield. What precisely are the adaptation constraints hindering lentil introduction in North America? How do varying photoperiods and temperatures exert influence on lentil production? Delving deeper, what genes govern the crop's sensitivity to photoperiods and temperatures? In this episode, Sandesh Neupane and Derek Wright share insights into their research on lentil adaptation and how they dissect the genetic mechanisms orchestrating the photoperiod and temperature sensitivity in lentils with multi-location trials and advanced image-based phenotyping. This groundbreaking work promises to contribute significantly to the breeding of well-suited lentil varieties tailored to thrive in North American conditions.
Tune in to learn about:
· Lentil and its nutritional value
· Lentil’s history
