Urban Food Forests with Dr. James Allen Apr 15, 2022

Show notes

"Urban food forests in the American Southwest" with Dr. James Allen.

Food forests are multi-level polycultures where fruit and nut trees, vegetables, shade trees, mushrooms, aquatic plants, and more can all exist in the same urban or rural space. They're known to have many benefits, both environmentally and socially; however, in more arid climates like the American Southwest, there are a few hurdles urban agroforesters must overcome. In this episode, Dr. Jim Allen discusses a recent survey of Southwestern food forests and how these mini-oases are learning to thrive in more arid climates.

Tune in to learn:

How food forests, agroforestry, urban agroforestry, and permaculture overlap
Success stories for food forests in the American Southwest
Ongoing challenges for food forest implementation
Future research and partnerships opportunities for food forests and agriculture at large

Microplastic Movement through the Soil with Yingxue Yu Feb 18, 2022

Show notes

"Current understanding of subsurface transport of micro- and nanoplastics in soil" with Yingxue Yu.

Microplastics can come from all kinds of sources, including broken down bottles, face and body scrubs, plastic bags, tire tracks, agricultural mulch films, sewage waste, and more. However, for as ubiquitous as these plastics can be, there's still much to be learned about how they move through our soils; how they're affected by their surrounding soils, weather, and animals; and their ultimate environmental impacts. This episode, Yingxue shares research from her recent review paper about what microplastic knowledge we already have and where we have yet to go.

Tune in to learn:

What shapes micro- and nanoplastics can come in
How water can impact micro- and nanoplastic transport
How weathering can impact micro- and nanoplastics
How micro- and nanoplastics interact with their surrounding plants and animals

Salt-Affected Roadside Grasses with Dr. Eric Watkins Dec 17, 2021

Show notes

"Review of cool-season turfgrasses for salt-affected roadsides in cold climates" with Dr. Eric Watkins.

Salt is commonly spread on roads in colder regions to help keep them clear of dangerous ice. However, salted roads can pose some environmental risks. Roadside turfgrasses can help alleviate some of those problems, but drought, heat, salt, ice, and more can mean a roadside is not always the happiest place for grass to grow. This episode, Dr. Eric Watkins walks us through some of the harsh conditions roadside turfgrasses face, the pros and cons of several popular grasses, and how we can wisely mix them for resilient roadside spaces.

Tune in to learn:

Why roads in Northern Climates get salted
What ecosystem benefits roadside turfgrasses provide
Which grasses perform best in roadside conditions
What are some tips for designing a healthy turfgrass mix
