208: Can You Cut Your Nitrogen Rate
October 30, 2023
In today’s episode, Rod sets down to talk with Dr. Richard Mulvaney to talk about the new research that he is doing with nitrogen. Can your farm cut nitrogen usage rates? Listen in as we tackle one of the top nutrients used by farmers. Can you regain control of your farm inputs to maximize your profits by cutting your rates? Discover the results from four studies that show low uptake efficiency from fall-applied ammonia, even with high nitrogen-supplying power. This is an eye-opening discussion that goes against the grain of conventional farming practices and asks us to reevaluate our practices.
