Saturated Riparian Buffers with Dr. Morgan Davis and Dr. Tyler Groh

Saturated Riparian Buffers are a relatively new conservation technique that aims to reduce water quality issues caused by traditional riparian buffers and tile drainage. However, their installation could potentially lead to increased levels of incomplete denitrification, resulting in excess nitrous oxide, a potent greenhouse gas, being released into the atmosphere. Drs. Morgan Davis and Tyler Groh work together to examine saturated buffer design and these potential environmental tradeoffs.

Tree Harvesting, Biomass Removal, and Soil Nutrient Reserves with Dr. Dave Morris

The potential impact of forest harvesting operations on environmental conditions for tree regeneration and growth can be substantial. Dr. Dave Morris, in collaboration with colleagues from the Canadian Forest Service, has studied the potential impacts of forest biomass removal on the sustainability of harvesting practices for 25 years.

Blooper Reel and Listener Survey

Happy birthday to us! In honor of our first birthday, we’ve put together a blooper reel. And to keep the good times rolling, we’ve developed a short, five minute survey to help us improve. Please take the time to fill it out, and enjoy some of our favorite flubs! Thank you to all of our amazing guests from year one! https://www.surveymonkey.com/r/N8V2YSL

High-Throughput Seed Phenotyping with James Clohessy

A Rube Goldberg machine is a machine intentionally designed to complete a task using complicated steps. James Clohessy and his team are doing the opposite. Using machine learning, web cameras, open software, and photogrammetry techniques, they’re developing low cost, high-throughput, high efficiency phenotyping systems, saving researchers hours of time on taking individual seed measurements by hand, such as height, width, and color, all while gaining greater detail about the seed such as volume and densit

Vadose Zone Gas Migration and Leaking Wells with Olenka Forde

Olenka’s research is related to hydraulic fracturing. She is interested in how we can safely extract oil and gas resources without negative impacts on fresh water supply, wildlife, and even humans. She does this by monitoring the fate and transport of gases in the subsurface and emissions at the ground surface at a controlled natural gas release experiment, essentially simulating what happens when a gas well leaks.

Turfgrass Colorants with Drew Pinnix

In kindergarten, we’re taught that colors can be one of seven colors of the rainbow. In reality though, color is much more complex, a mixture of hue, brightness, and saturation. Garland (Drew) Pinnix thinks a lot about color, specifically in relation to turfgrass colorants, products used to keep fields green through the winter months. This episode we discuss his work rating colorants by color, longevity, staining power, and viscosity to develop guides for turfgrass managers.

Hydrological Observatories with Dr. Heye Bogena

“Toward Better Understanding of Terrestrial Processes through Long-Term Hydrological Observatories” with Dr. Heye Bogena. Hydrologists gather as much information as they can about water in order to understand current water trends and to predict potential water patterns in the future. In a changing climate, this is more crucial than ever. In this episode, we’ll take a deeper look at how hydrological observatories are making strides in understanding water and its movement around the world.

Precision and Sustainable Agriculture with Dr. David Clay

Precision Agriculture Basics with Dr. David Clay Across any farm field, there are discrepancies in how given points of the field react to similar management practices. If farmers understand what causes those discrepancies, they can fine tune management to optimize fertilizer and pesticide use, inputs, and time. Dr. Clay discusses how tech has made it possible to make great management decisions from data obtained miles above a farm.

The OSU Hand Planter with Dr. Bill Raun

“Hand Planter for the Developing World: Factor Testing and Refinement” with Dr. Bill Raun In Central America, South America, and Africa, thousands of acres of land have landscapes unsuitable for mechanized agriculture. But while technology in chemical seed treatments has advanced, technology in hand-planting techniques has not, resulting in farmer exposure to seed-friendly chemicals that can lead to sickness and even birth defects in humans. Dr. Raun discusses a new hand planter to address this.

Sediment and the Health of the Great Barrier Reef with Dr. Peter Hairsine

“Review: Sediment-Related Controls on the Health of the Great Barrier Reef” with Dr. Peter Hairsine. Climate change and human-caused pollution have amplified threats to the Great Barrier Reef (GBR), but Dr. Peter Hairsine is working on monitoring and researching the reef’s responses to these changes with an ultimate goal of its preservation. This episode, we discuss current stresses to the GBR, including warming ocean temperatures, deteriorating river water quality, and tropical storms.
