A weekend feature for you - Horses to horsepower

How much has the type of agricultural equipment available to you, determined how you farm? How much did the type of machinery available to your father or grandfather influence the way they farmed?

Obviously, the kind of equipment available to farmers has changed a lot over the decades, and so have general farming practices. But did we change how we farmed and looked for machinery to accommodate those changes, or did the machinery available to us at the time change our methods?

Throughout the last century, a handful of inventors saw a way to do things better, and created machines that could improve farming practices. Then the rest of us changed what we did when those new and innovative machines became available.

Dr. Emerson Nafziger: Nitrogen Fertilizer Rates for Corn

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.
