Nitrogen Strategies for a New Year
In this episode we explore nitrogen: its different forms, how to retain it in the soil, application timing, and why nutrient balance is important to the health of your soil and crops.
Listen along as guest presenter Jeremy Swanson of Agronomy Rx (Webster City, IA) discusses several aspects of nitrogen and its proper use in your agronomy program.
2:31 Jeremy's nitrogen presentation begins
3:49 Introduction to the different types of nitrogen used in farming
6:05 Discussion of UAN and its 3 components
8:40 How to protect against the offgassing of urea
11:12 Biological reactions that convert nitrogen into plant-available forms
12:40 The role of carbon in holding nitrogen in the soil
18:15 Preferred nitrogen sources (and why)
23:23 Products/strategies to reduce leaf burn from nitrogen application
24:55 When to apply various forms of nitrogen
33:00 Importance of sulfur to corn germination
36:25 Importance of amino acids; plant-based amino acids as nitrogen source
41:33 Notes on sulfur use
47:42 When is it too late to apply nitrogen?
50:23 Floury vs. flinty corn and nitrogen applications
52:32 Importance of healthy microbial populations in the soil
59:55 Importance of balanced soil biology to crop health
1:15:00 Relationship between potassium and nitrogen; "luxury consumption" and lower yields
1:23:23 Soil fungi and plant health: Mother Nature's "clean up crew"
1:29:55 Why is ammonium important for grain fill?
