Potato Farming Isn’t About Inputs. It’s About Energy.

For years, potato production has been measured by inputs—fertilizer, water, fuel, and crop protection products. While these investments are essential, they don’t tell the whole story. A more useful way to think about potato farming is through the lens of energy. Every potato harvested begins as captured solar energy. The crop’s ability to intercept sunlight, […]

Before You Plant: Key Potato Seed Decisions That Shape the Season

Potato seed decisions often happen fast. Planting windows tighten, field conditions shift, and growers may have limited options available. But even under pressure, these early decisions can have a major impact on crop establishment and season-long performance. I recently joined Don Northcott for a Spud Smart panel discussion on potato seed quality. The conversation focused […]

What Are Your Seed Decisions Really Costing You?

Every grower knows seed matters—but how much does it really matter? Seed isn’t just another input. It sets the trajectory for the entire season. Emergence, stand uniformity, and ultimately yield all trace back to the decisions made before planting. But “good seed” isn’t always straightforward. Growers are constantly balancing quality, cost, disease risk, storage, and […]

A New Framework for Soil Performance: Introducing the Catalyst-Activated Cycle (CAC) Manuscript Series

Agriculture is entering a new era—one where soil is no longer evaluated solely by inputs or practices, but by measurable performance. Recently, I published a six-part research series on the Catalyst-Activated Cycle (CAC) through Zenodo, an open-access platform widely used across European research and policy communities. Each manuscript carries a permanent DOI and is freely […]

Why Ongoing Learning Pays Off—Season After Season

Spud Smart recently published an article that reinforces something I’ve seen consistently across growing regions and seasons: ongoing learning is one of the most productive investments a grower can make. When we talk about productivity, the conversation often turns quickly to inputs, equipment, or acreage. But some of the most meaningful gains happen off the […]

Why Marketable Yield Matters More Than Total Yield

Earlier this month at Potato Expo 2026 in Texas, I had the opportunity to participate in a panel discussion on potato quality alongside Seed World U.S. Editor (on behalf of Spud Smart) Aimee Nielson and Jeff Douglas of Douglas Agricultural Services. Our goal was simple: help growers with real solutions.Our point of emphasis: prioritizing marketable […]

New Webinars for Growers: Tackle Potato Quality Challenges Head-On

Potato growers today face a familiar—but evolving—set of challenges: soil-borne diseases, market pressure for higher quality, and the constant need to protect yield while managing risk. At Strike Fumigants, we believe better outcomes start with better information. That’s why we’re excited to highlight two new, expert-led webinars designed to help growers dig deeper into the […]

From South Africa to Canada: Four Lessons on Soil Fumigation

In my latest article for Spud Smart, I take a closer look at what I learned working with a frustrated potato grower in coastal South Africa—and how those same lessons apply to farms in Canada. By adjusting how Chloropicrin (known as Strike in Canada) was applied, we turned a struggling field into a success story. […]
