I took a pasture, added 3-4 inches of compost, tilled it and my results look like this:

Soil pH: 7.2
EC: 0.64
OM: 8%
Nitrates: 101
CEC: 19
P: 231
K: 1205
Ca: 3520
Mg: 55

I'm concerned about the K levels. I've worked with hundreds of soil samples but haven't seen levels that high. Will it cause me issues? Not just the K itself, but obviously the cation ratio is not where it should be.
I've added sulfur to pull that pH down a touch but it will take time, also added some BMO, Cu, and Mn... I'm pretty good on micros.
I'm assuming I may not be applying any N this year?
