What cover crops were used? N immobilization is expected from grass cover crops like rye. Would include a winter-hardy legume to prevent immobilization. Here in the southeast, we typically see mild to substantial yield improvements w cover crops.

Early termination is critical, IMO.

Looking at The source of this study before a guy even watches it. You know that this video will be stereotypical ignorance About yield and cover crops with 0 talk about soil structure and soil. Zero talk about inputs, soil health will be mentioned but not measured, and full rate of chemicals, fungicides, fertilizer will still be used let's roll the tape Why did you select cereal rye and barley? You never spoke about a goal of using cover. What are they using to determine success or failure? If you are using yield? Yield is the worst way to quantify a define. Cover crop success or failure. what are you not doing in your current system? That would allow a cover crop to increase your yields? Especially on the first year of a trial. Oh well thank god you did a bunch of replicated trials. Let's mention water infiltration, reduced erosion, Reducing inputs because you have increased Nutrients in the soil. But give zero input of them to dollars in vs dollars out. Not one mention about being in the field sooner because you have less mud. Thousands of replicated trials have been done in iowa to show zero yield response between your conceal versus surface.
