Chris Armstrong

North Bend, Neb. strip-tiller Chris Armstrong was just over the age of 30 when he made the switch to strip-till in 2014 and that same year, enrolled in a nutrient management program, investing $10 per acre in creating a database with a goal of more accurately applying fertilizer based on field-specific prescriptions.

While he admits it was somewhat of a gamble, it’s one that contributed to an overall yield boost of 10 bushels per acre in corn and lowered his ratio of applied nitrogen to less than 1 pound per bushel across his 1,900-acre corn and soybean operation.

“We can determine how much N is needed for a particular soil type and climate. It’s been a key component in our pursuit of input savings,” Armstrong says. “It takes about 2.6 bushels per year to see a return on investment and even with cheap corn, I’ve made up far more than 2.6 bushels on average between the N and fertility savings.”

During a classroom session at the 2018 National Strip-Tillage Conference, July 26-27 in Iowa City, Iowa, Armstrong will discuss how he’s deployed data-driven tools to evolve his strip-till system, including return on investment and opportunities for improvement.

The 5th annual National Strip-Tillage Conference will be held at the Marriott Coralville Hotel & Conference Center and feature 2 days of strip-till education through an array of thought-provoking general sessions, strategy-packed strip-till classrooms and highly collaborative strip-till roundtable discussions.

Registration is available for just $269, and attendees who register their farm and family members receive additional savings. For more information and to register for the conference, visit
