Episode Title: Organic Certifications with Harriet Behar

Show notes:

Getting organically certified is one of the first and most important steps to transitioning to organic farming, but how does one actually go about it? Harriet Behar has worked in organic systems for over thirty years and is an expert on the regulations, processes, and requirements for getting organically certified. Join us and host Dr. Erin Silva as we discuss this crucial process in part one of our four part series on transitioning to organic farming.

Tune in to learn more about:

• What goes into creating an Organic System Plan
• How knowing the requirements ahead of time can save time when transitioning to organic farming
• How to avoid comingling of organic and non-organic crops and seeds in parallel organic and conventional operations
• What happens during an organic inspection
• How crop rotations differ in conventional and organic systems

In North America, standards for soil health and fertility in organic systems are regulated at the federal level. But for those transitioning to organic farming, it can be difficult to know how to meet those standards without access to the same toolkit they used while practicing conventional farming. Join us and moderator Chris Boomsma in this last installment of our four part series on transitioning to organic farming, where we discuss tips and trends to organically manage soil health, fertility, and biology, as well as some closing thoughts from series moderator Dr. Erin Silva.

Tune in to learn more about:

• What are the current regional and national trends in organic farming
• How manure and cover crops can be used in nutrient cycling in organic systems
• What the current literature has to say about organic management of key nutrients such as nitrogen and phosphorus

"Genome-Wide Association Studies in Apple Reveal Loci for Aroma Volatiles, Sugar Composition, and Harvest Date" with Dr. Zoë Migicovsky, Dr. Carsten Pedersen

Apple breeding can take a long time. Because each seed is the progeny of two different trees and each tree takes five to six years to produce its first fruits, breeders can be waiting years, if not decades, to see the results of their hard work. Drs. Zoë Migicovsky and Carsten Pedersen are working to change that. By comparing the genomes of varying apple cultivars and their phenotypic data (traits you can discern via the five senses), Zoë and Carsten aim to pinpoint which genes are responsible for which traits. With that information, simple DNA testing may be able to shave years off of each round of breeding, helping breeders create better apples for your shelves in far less time.

Listen in to learn:

• What is a genome wide association study?
• What is the Pometum?
• Why is it important to pair both genomic and phenotypic data?
• How can knowing differing sugar ratios improve apple products, such as ciders or wines?

"Winter Phosphorus Release from Cover Crops and Linkages with Runoff Chemistry" with Dr. Merrin Macrae

Cover crops can offer a variety of ecosystem services, including reducing soil erosion. However, in colder climates, where cover crops can freeze and die over the winter, there is the possibility that the Phosphorus within cover crops can then leach into surface runoff. Dr. Merrin Macrae and her team decided to dive deep and discover whether or not this trade-off exists and, if so, to what extent.

Listen to learn:

• What do Nalgene bottles and ping pong balls have to do with research?
• What is it like to do field research in the winter?
• How can Twitter lead to working research relationships with farmers?
• Which factors contribute most to surface P runoff?

"Plant Species and Hydrology as Controls on Constructed Wetland Methane Fluxes" with Karla Jarecke and Dr. Terry Loecke

Wetlands are important ecosystems that provide many important services, such as assisting in water quality, flood control, erosion protection, carbon removal and storage, and biodiversity. Hydrology is the study of water, specifically in how it moves throughout the landscape.

Combine them with the conundrum of methane production in wetland plant species, and you've got the makings of a fascinating research project. Specifically, Karla Jarecke and Terry Loecke's project. By testing methane production in two common wetland species under both lab and field conditions, they worked to answer important questions about not only how methane production, hydrology, and wetland species work together, but also how we can better plan for the creation and care of constructed wetlands.

Listen in to learn about:

• The lifecycle of methane within wetlands
• The different kinds of flora and fauna that live in them
• How a parks program turned a would-be landfill into a new wetland
• How field and lab conditions can differ, both in logistics and results

"What We Talk about When We Talk about Soil Health" with Dr. Ryan Stewart.

Soil health is an important topic for today's scientists, but how do we quantify it, and when we talk about "healthy soils," what do we even mean?

Dr. Ryan Stewart and his team set out to answer just that. Doing a meta-analysis on dozens of studies listed in The Soil Health Institute's Research Landscape Tool, Ryan and his team compared different soil health indicators to determine what scientists are measuring, how they're measuring it, and which are the most valuable in actually determining soil health.

Join us to learn:

• How measuring soil health is similar to measuring health in humans
• What kinds of soil health indicators scientists measure
• How these indicators can be grouped and compared across multiple studies
• Which indicators are the most helpful in measuring soil health

"Celebrating the 350th Anniversary of Phosphorus Discovery: A Conundrum of Deficiency and Excess" with Drs. Andrew Sharpley, Helen Jarvie, Don Flaten, and Peter Kleinman.

350 years ago, German alchemist Hennig Brandt accidentally discovered phosphorus during his quest to find the philosopher's stone. As it turns out, phosphorus can't turn base metals into gold, but it is one of the most important elements for sustaining life on earth. Join us for this episode as we discuss the discovery of phosphorus, its uses, how we harvest it, and interesting facts about its storied past.

Listen to find answers to questions such as:

• How was phosphorus originally discovered?
• Why was it called the "Devil's Element"?
• What do urine, guano, and human bones have to do with mining phosphorus methods?
• How can we efficiently and wisely manage phosphorus today?

"Nitrous Oxide Emissions from Saturated Riparian Buffers: Are We Trading a Water Quality Problem for an Air Quality Problem?" with Dr. Morgan Davis and Dr. Tyler Groh.

Riparian buffers are areas of perennial vegetation planted around stream banks and other riparian zones to protect against soil erosion and nutrient leaching. However, tile drainage systems—piping laid under fields to keep them from becoming too saturated—are designed to bypass riparian buffers, leading to potentially harmful levels of nutrient leaching. Saturated Riparian Buffers are a relatively new conservation technique that aims to reduce those water quality issues by redirecting excess water back into the soil. 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.

This episode, listen in to find answers to the following questions:

• What is tile drainage, and how is it installed?
• How does denitrification work, and why is it a necessary process?
• In what ways can we attempt to improve saturated riparian buffer design?
• Is there really a tradeoff in air and water quality when installing saturated riparian buffers?
