Been putting on a good rate via broadcasting on top every year since 2017 to corn and bean ground, but the crop prices really aren't supporting investments that won't fully pay off the following year. Still intending to do a full rate of nitrogen for corn, sulfur, full herbicide cocktail for excellent weed control, and fungicide in 2025. To anyone who skips a year of broadcast P and K, do you notice much difference? Should I just risk the crop prices being the same next year, and put on a full rate regardless? Or am I not losing much yield just skipping one year? The way I see it, either crop prices fall next year, and P and K prices have to tank. Or crop prices rise, and I can put on a double rate next year. Thanks!
I would look at most recent soil test to see what you have in the bank. Then calculate removal from this years corn(include grain and stover). 200 bu/a corn removes more P and K than you think in grain and stover combined. 250 bu/a corn removes a tremendous amount of P and K. Another thing to consider is the impact if this dry weather pattern continues into next year. K can get trapped in clay layers in dry weather and become unavailable. |
Considering not applying P and K this fall.
