“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.

“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
