Fontanelle, IA | Your available P1 phosphorous pool is low relative to reserve p2 soil phosphorous. Typically p1 is about 50% of p2 reserve. That is across all 3 samples that look to come from 3 different soil types (looking at Cec values).
I would say that you MAY have a phosphorous availability issue for your small grains.
With your high pH levels, might be tying up available phosphorous?
