Solving Soil’s Microscopic Mysteries: Introduction to Metagenomics

Like your gut microbiome, the soil counterpart is composed of all the microorganisms (or “microbes”) that live there. Having this information is incredibly valuable to those who are interested in measuring soil health, including: farmers, agronomists, scientists, and any business invested in agriculture.

How do we know what microbes are in the soil?
There are a few different technologies that can shine a light on the invisible world of microbes. Because it provides the most clear picture, Trace Genomics uses DNA sequencing to understand the soil microbiome. In order to understand how that works, let’s back up a little bit…

What is DNA?
DNA is known as the “blueprint of life” because it contains all the information necessary to “build” a living organism. It’s a biological molecule made up of four different chemical building blocks called bases; you can think of it like a language with four letters in the alphabet.

Video: Soil Under Siege | Black Dot, Microbial Health & the Future of Fumigation

Black dot is on the rise. Soil health is under pressure. And growers are caught in the middle: trying to protect their crops while keeping the biology beneath their boots alive.

In this unscripted expert panel, Spud Smart brings together three top minds in potato production to tackle the biggest questions in soil management today:

•Dr. Gary Secor (North Dakota State University) — Renowned plant pathologist with deep expertise in black dot and soilborne diseases

•Joy Youwakim — Soil microbiologist focused on microbial communities and crop resilience

•Dr. Chad Hutchinson (TriCal Group) — Global leader in fumigation, agronomy, and sustainable soil solutions

What they cover:

• What’s actually working against black dot

• How fumigation affects soil microbes

• Whether “living soil” and chemical tools can work together

• How to measure ROI in disease control
