    Improving Maize Pollination Efficiency with Dr. Dylan Schoemaker

    Improving Maize Pollination Efficiency with Dr. Dylan Schoemaker

    “A practical method to improve the efficiency of pollination in maize breeding and genetics research” with Dr. Dylan Schoemaker
    Mismatched pollination times can make desirable genetic matches beyond the reach of practical plant breeders. Storing pollen is one solution, but limitations in cost and feasibility can make viable pollen storage tricky. This episode, Dr. Dylan Schoemaker shares his work developing cheaper, easier methods of pollen storage to extend shelf life, increase flexibility in breeding workflows, and bring those plant matches back within reach.
    Tune in to learn:
    ·         What issues make pollen preservation difficult
    ·         How long this method can extend pollen life
    ·         How clumping can affect pollen preservation
    ·         How plant breeders avoid cross-contamination

    Bioenergy Cropping on Marginal Lands with Dr. Dileepa Jayawardena

    Bioenergy Cropping on Marginal Lands with Dr. Dileepa Jayawardena

    “Comparative productivity of six bioenergy cropping systems on marginal lands in the Great Lakes Region, USA” with Dileepa Jayawardena.
    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. 
    Tune in to learn more about
    ·         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?

    Soil-Landscape Rehabilitation with Dr. Sharon Schneider

    Soil-Landscape Rehabilitation with Dr. Sharon Schneider

    “Key soil properties and their relationships with crop yields as affected by soil-landscape rehabilitation” with Dr. Sharon Schneider.
    Soil erosion is one of the major issues in agriculture that causes loss of the topsoil layer, reducing soil health and crop productivity. There are several ways to check soil erosion and its impacts on crop and soil health. One of the potential strategies to reduce the effect of past soil erosion is to reverse the soil erosion process by moving soil from where it was deposited by erosion to where soil was lost by erosion. In this episode, Dr. Sharon Schneider shares her research on replacing topsoil in eroded landscapes.
    Tune in to learn more about
    ·         What are the impacts of soil erosion on crop productivity and soil properties?
    ·         What are strategies for reducing soil erosion?
    ·         What is the importance of soil organic carbon?

    Recalibrating the Pennsylvania PSNT with Dr. Charlie White

    Recalibrating the Pennsylvania PSNT with Dr. Charlie White

    “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

    Precision Agriculture for Improving Wheat Yield and Quality with Olga Walsh

    Precision Agriculture for Improving Wheat Yield and Quality with Olga Walsh

    “Precision nitrogen management for improving yield and protein content in wheat” with Dr. Olga Walsh.
    Nitrogen is one of the most important nutrients for crops, which is required in large amounts for crop production and demands precise nutrient management methods due to its highly mobile property in plants and soils and high chances of leaching. Precise nutrient management is also important for improving the yield and quality of grains, minimizing the input, and maximizing the efficiency. Assessing the real-time plant growth, biomass production, and nutrient depletion in the soil using different precision agriculture techniques like drones, remote sensing, unmanned aerial vehicles (UAVs), and other camera-based devices helps optimize nutrient management. In this episode, Dr. Olga Walsh shares her research on precision nitrogen management for yield and protein content estimation on spring wheat and sugar beet by using different hand-held sensors, drones, and remote sensing approaches.
    Tune in to learn more about
    ·         What values are best to look for when doing remote sensing in wheat
    ·         How drones, remote sensing, and camera applications are helping predict biomass and nutrient requirements
    ·         What yield and protein content was estimated from the sensors tested
    ·         How hand-held and UAV sensors compare

    Mitigating Coastal Eutrophication with Drs. Wafa Malik and Patrick Durand

    Mitigating Coastal Eutrophication with Drs. Wafa Malik and Patrick Durand

    “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
