Podcasts about soil physics

Solar has been getting a lot of attention in the past couple years and counties across Virginia have been passing stringent regulations on new solar developments. This week we spoke with Dr. Lee Daniels, Professor Emeritus of Land Rehabilitation and Dr. Ryan D. Stewart, Professor of Soil Physics & Hydrology, both at Virginia Tech about the effects of solar farms on the land and soil. And in the second half of the episode, Nathan Moore is back to talk about some other solar farm considerations.     Read the white paper: Soil-Site Management Protocols & Best Management Practices (BMPs) for Utility Scale Solar Site (USS) Development and Management in Virginia  https://www.deq.virginia.gov/home/showpublisheddocument/24050/638531957239470000

Michael Box from Sustainable Village is BACK and code GROWCAST is live for 10% off Blu Mats for this month only! Michael joins the program again for another banger of an episode all about watering and irrigation. Michael starts off with a brief history of irrigation practices, and how the brilliant ancient practices were eventually evolved into our modern irrigation products. This leads to a conversation about how water operates within a medium physically, and why it's more complicated than just measuring "how much" water is in your soil. Michael also recaps on his work with moisture retention curves AKA moisture release curves- and how water doesn't dry out of all mediums equally! Michael points out the finer points of understanding soil saturation, and how the different properties of your medium affect the physics within.

It may be a surprise how complex and system soil environments are. Given how important it is to growing food and it and the more general impact of agriculture on climate change, I thought it an important topic. I discuss the science of soil and the role of sustainable farming practices with my guest Mahdi Al-Kaisi. Dr. Mahdi Al-Kaisi is a Professor Emeritus of Soil Physics at Iowa State University . He has over 30 years' experience in soil carbon dynamics and climate change mitigation using Climate Smart Agriculture practices. Currently, he is providing consulting services in these areas through Soil Carbon Metrics, LLC.

Visit our sponsor: https://www.sound.ag/ LandScan: https://landscan.ai/ Today's episode with LandScan founder and CEO, Dan Rooney. We could spend the entire episode going through Dan's background and expertise in this field, but I wanted to get right to the interesting work he's doing at LandScan, a company they've been working on quietly since 2019. They've developed what they call “the most advanced and practical site characterization and analysis technology. These multiple layers are a series of digitally synchronized tools and techniques that create a unique understanding of the relationship between crop performance and the growing environment”. Dan will tell us all about this in today's episode and makes a compelling case for why this is a critical missing piece in digital agriculture.  Just a little bit on Dan's impressive background: He is a scientist, inventor, and entrepreneur who has a PhD in Environmental Monitoring with an emphasis on remote sensing and spatial information analysis from the University of Wisconsin-Madison and a master's in Soil Physics from Texas A&M. Following his master's Dan's early career with with a geotechnical firm where he built sensors for deep subsurface characterization. He was drawn to apply his discoveries from that field to near-surface applications which of course led him to agriculture. After his PhD, he dove right into entrepreneurship. And that is where today's episode begins.

Inaugural episode of The Houseplant Coach Podcast, where Veronica of Oh Happy Plants nerds out real hard on all things houseplant!

This week’s podcast, sponsored by Yetter Equipment, features Aaron Daigh, Associate Professor of Soil Physics & Hydrology, North Dakota State University. Daigh discuss why deep tillage is never the answer to alleviate soil compaction, what visual indicators mean growers have soil compaction issues, the yield impact soil compaction can have and more.

“We’ve been having significant rain events the last couple of years. 2 inches, 3 inches, 5 inches at a time. And I’m just curious, what can I do in my soil health program to ensure that the soil keeps as much rainfall as possible? I hate to see soil leaving my fields after working so hard in no till and cover crops to keep it in place.” - Bill Spiegel, Kansas Farmer and Successful Farming Magazine Editor Dr. Aaron Daigh is an Associate Professor of Soil Physics and Hydrology at North Dakota State University in the Soil Science Department. His focus is studying how things move in the ground including water, chemicals, heat and the soil itself. “When you get very heavy rainfall…..you can count on no matter what you’re doing out in the field that some portion of that is going to go to runoff because most soils just simply cannot take in that much water in that short of a period.” - Dr. Aaron Daigh The water that is absorbed by the soil then adds value based on where it is stored. If it is stored shallow, in the first 6 inches, you can run into issues with “root rot, fungal diseases, wilting and drowning of that crop. “The portion of the water that goes deeper into the soil profile is ideal because you put water to where it can be stored for later for that crop when it’s needed.” Another added benefit to having water infiltrate deeper in the soil profile is keeping the soil stronger which will reduce future erosion and support equipment during harvest. Dr. Daigh suggests farmers make every attempt to not disrupt the soil anymore than necessary in order to increase its strength and contribute to water infiltration. “Reducing the amount of disturbance that you have to that soil through aggressive tillage practices, helps get more water down these big macro pores that move water down deeper into the soil profile to be stored and prevent abundance of runoff and water erosion.” Dr. Aaron Daigh Cover crops will also reduce disruption of soil by major rainfall which can be substantial. “The higher the residue rate, the slower that water’s going to move across and have a chance to infiltrate down into the soil and prevent what is running off from picking up speed as it goes down the landscape.” Follow the link www.NDFieldCheck.com to participate in our next question and answer segment to share your questions and get them answered by the experts!

Soil compaction is always going to be a hot topic following a trying harvest season. That holds true for much of the eastern Prairies and northern U.S. states this spring. Aaron Daigh, assistant professor of Soil Physics at North Dakota State University says that the 2019 growing season started off wet in the spring, which... Read More

Explore the scientific principles forming the foundation of soil health. Dr. Aaron Daigh of North Dakota State University joins us to discuss the impact of movement and distribution of water, heat, and nutrients in the soil. Dr Daigh draws an analogy between pores in the soil and plumbing in a building. Through the natural processes of freezing, wetting, drying, and thawing pores are developed in the soil. These pores are crucial to nutrient and water retention. He shares the effect that tillage practices have on heat transfer and retention within the soil as well as to the pore size and distribution. Understanding these scientific principles can lead to more informed decisions on farming practices. Dr. Daigh shares the ongoing research in this field and where the focus is shifting. “It’s kind of like taking all the piping in your house or the building or in a chemical plant and rearranging it to the way that you want…..When you go in and you till a soil you are kind of homogenizing everything. You’re making all the pipes kind of very similar to each other at least in the depth that you’re tilling at.” - Dr. Aaron Daigh “When you go into a no-till or reduced till system…. you have a whole bunch of small pores and those pores are what can really hold onto water longer. They can hold onto nutrients longer and keep it available in a spot that the plant can use later on.”  - Dr. Aaron Daigh This Week on Soil Sense: Meet Dr. Aaron Daigh and learn what it means to be a soil physicist Explore how tillage disrupts the natural pores in the soil and affects the movement of water and nutrients Dr. Daigh teaches us how the different sized pores are developed in the soil and the benefits they provide.
