ID Farm Pioneers Regenerative Ag Practices for Potato Growing

Apr 27, 2023

By Eric Tegethoff

A farm in Idaho is pioneering a new way to grow the state's most famous crop: potatoes.

The pioneering method is being demonstrated on Ladd Wahlen's fourth-generation farm and will involve using regenerative practices to grow potatoes. Wahlen, who researched regenerative practices in college, said using such methods for potatoes is uncharted territory, but he argued it will ultimately benefit the land.

"I want my soil to be healthy and I want it to be sustainable for the generations to come," Wahlen stressed. "Because it's a family farm, family enterprise, and we want it to continue and we want to be able to have good, healthy soil that's capable of producing good, healthy products."

Wahlen and his wife also own a potato chip company called Roots Potato Chips. He noted more consumers are looking for products which have been made sustainably and provide benefits to the environment.

Brad Johnson, agriculture strategy manager for The Nature Conservancy in Idaho, which is partnering with Wahlen on the demonstration farm, said the farm will use techniques like reduced tillage, cover crops and pollinator plant species to reduce the use of insecticides. They are also testing plant companion species to reduce the use of fertilizers.

Video: Dr. Emerson Nafziger: Nitrogen Fertilizer Rates for Corn

The Crop Science Podcast Show, Dr. Emerson Nafziger from the University of Illinois breaks down decades of nitrogen research. From the evolution of N rate guidelines to how soil health and hybrid genetics influence nitrogen use efficiency, this conversation unpacks the science behind smarter fertilization. Improving how we set nitrogen fertilizer rates for rainfed corn is a key focus. Discover why the MRTN model matters more than ever, and how shifting mindsets and better data can boost yields and environmental outcomes. Tune in now on all major platforms!

"The nitrogen that comes from soil mineralization is the first nitrogen the plant sees, and its role is underestimated."

Meet the guest:

Dr. Emerson Nafziger is Professor Emeritus of Crop Sciences at the University of Illinois at Urbana-Champaign, with degrees in agronomy from Ohio State, Purdue, and Illinois. His research has focused on nitrogen rate strategies and crop productivity. He co-developed the Maximum Return to Nitrogen (MRTN) model, which is widely used across the Midwest. His research spans N response trials, hybrid interactions, crop rotation effects, and yield stability.
