bring up P and K - I'd have to look at my food plot book, but I thought they recommended 30 and 150 ppm respectively. That is going off my questionable memory though, but I think that is pretty close. Your organic matter and pH are good, so once you correct P and K you will get a good brassica crop. But to be honest I'm surprised you haven't had decent luck recently since your numbers aren't too bad at all overall. When and how did you plant your brassicas before and what happened? Usually plant middle of July northern Wisconsin. Think being cheap on the N was the biggest problem

Two opportunities I see for ya.
1. Don't spray quite so far in advance. 2. Switch to ammonium sulfate at 250 lbs/ac or throw on ~l50 lbs/ac gypsum with your urea. You're low in sulfate sulfur, and that's a key part of getting nitrogen into your plant.

I've had good luck disking my plot first a month before my expected planting date. Then I broadcast the brassica seeds, cultipack and then spray. The spraying step at planting time will kill all competition and give the new seeds a jump start on the weeds.
I think adding more nitrogen and spraying just prior or after planting will improve your luck. The sulfur suggestion is a good one as well.
I've also had decent luck skipping the disking step and simply broadcasting seed and fertilizer then spraying round up on the freshly seeded plot. That option requires timely rain though, but it certainly can work well. You might need to increase your seeding rate with that option though.

It's not on your test. There's some Bobcat wizardry going on there. If you're not putting it on, and you're not in soggy anerobic soil, you're likely low and it's just cheaper to put it on than go back and get a complete test done.

Is that something you should do every year or every couple with the gypsum?

Is that something you should do every year or every couple with the gypsum? I do it every year to feed the soil all year at a rate of around 250 lbs/ac. If/when I get my OM over 5%, I'll probably quit with it and let the critters do the work. I just try to do it at the same time each year, and I usually screw that up if I'm protesting the humidity.
