    Episode 6- The Rule of 1.2

    Welcome back to this 6th, bonus, episode of “The Story of Nitrogen”! This episode is all about nitrogen fertilizers and how we decide what rate of fertilizer to apply to our ground. This is a question I and many others have tried to tackle in our careers, and one whose answers regularly surprise and humble us. This episode is also about another question, one which anyone can relate to regardless of whether they work in agriculture or not, one which every person will have a different answer to: “How good is good enough?” Interviewees: Emerson Nafziger, Fabian Fernandez, Paul Trcka
