"Transitioning from conventional to cover crop systems with minimum tillage does not alter nutrient loading" with Drs. Joby Czarnecki and Beth Baker of Mississippi State University

Cover crops are often lauded as agricultural heroes boasting of a variety of ecosystems services and benefits to farmers and the world. But are these crops always the best option and do they always provide benefits wherever they go? In this episode, Joby and Beth join us for a more nuanced look at the benefits of cover crops and how research can make sure farmers are really applying the best strategies for their farms.

Tune in to learn:

· Which environmental factors can undercut conservation practices

· What trade-offs can exist when adding cover crops to an optimized system

· How cover crops affected water quality in the study

· What factors farmers should consider when introducing cover crops

Global Reliance on Corn Belt Dent with Dr. Stephen Smith May 19, 2023

Show notes

"Global Dependence Upon Corn Belt Dent Maize Germplasm: Challenges and Opportunities" with Dr. Stephen Smith, Affiliate Professor at Iowa State University

Plant breeders are constantly trying to find the best crosses to increase the traits farmers and consumers want. However, continually crossing the same varieties can decrease the genetic gene pool over time, making plants susceptible to certain pests, diseases, and other stressors. To help understand the depth of the gene pool and to better understand how reliant we are on certain crop varieties, Dr. Stephen Smith and his team attempted to survey which maize varieties are bred and used the most. On this episode, we dive deep to discover what his team turned up.

Tune in to learn:

· What obstacles can exist for researchers trying to gather worldwide breeding data
· Why pre-breeding is a crucial complement to the newest tech
· Which countries keep the best maize breeding records
· How reliant we are on certain maize varieties

The Roots of Drought Resistance with Dr. Maryse Bourgault and Jessica Williams Feb 17, 2023

Show notes

"Relationships between roots, the stay-green phenotype, and agronomic performance in barley and wheat grown in semi-arid conditions" with Dr. Maryse Bourgault and Jessica Williams.

Roots are an important factor in drought-resistance as they are the primary way by which plants uptake the water they need to survive. However, measuring roots can be a difficult, time-consuming, and destructive process. In this episode, we discuss Dr. Maryse Bourgault and Jessica William's work to better understand how drought, root systems, and other traits relate by partnering across studies in greenhouses and the field to study traits that get to the roots of drought resistance.

Tune in to learn:

· How root system traits relate to drought resistance

· Which root traits work best for different cereal and pulse crops

· How to make a root roll-up

· How minirhizotrons can help gather root trait data without damaging the plants and soil

3D Fruit Form Reconstruction with Dr. Mitchell Feldmann Jan 20, 2023

Show notes

"Cost-effective, high-throughput phenotyping system for 3D reconstruction of fruit form" with Dr. Mitchell Feldmann

Various research and breeding programs study phenotypical traits—or traits that can be discerned via the five senses—to evaluate the quality of their target crops. However, getting data on these traits, often via human-made measurements, can be time-consuming, subjective, and inaccurate, hampering research efforts. This episode of the Field, Lab, Earth podcast, Mitchell discusses his work developing a high-throughput, affordable way to capture one important phenotypical trait: fruit shape.

Tune in to learn:

Why it's important to accurately measure fruit shape
How consumers consider shape, size, and color when making purchasing decisions
How Mitchell and his partner developed their system
What kinds of fruits and other shapes they tested
