"Redesigning traditional weed management practices in faba bean fields to optimize food-feed production in the smallholder system" with Peter Thorne.

Researchers work hard to develop best practices and recommendations for farmers. However, cultural practices may affect how farmers do or are able to implement these recommendations on their farms. This episode, Peter discusses his work bridging the gap between researcher recommendations and farmer needs in smallholder Ethiopian farms.

Tune in to learn:

• What kinds of farmer requirements may impact researcher recommendations
• How regional traits can impact farmer implementations
• What to consider when balancing food-feed production
• Tips for approaching sustainable intensification in smallholder farms

There are multiple tools for farmers to work with when deciding Nitrogen recommendation rates. All of them operate on the spectrum between mechanistic and empirical approaches. In this episode of the Field, Lab, Earth podcast, Drs. Brian Arnall, Josh McGrath, and Wade Thomason discuss the key differences between these approaches, how they interact with accuracy and precision, how they intertwine with each other, future research for recommendation tools, and how farmers can best make decisions for their farms. Tune in to learn:

• What the difference is between accuracy and precision
• What the difference is between mechanistic and empirical approaches
• How these approaches interface with Big Data and environmental concerns
• What factors most impact which approaches farmers use

"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

"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

"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
