What to do, what to do
Got some soil tests back a few days ago. Grid sampled on an 80 that had a good bit of hog manure knifed in several years ago. P and K numbers all over the place without a pattern. P reading from 30 to 120 lbs per acre and K from 230 to 420 lbs per acre. Average CEC about 15 and only varies by plus or minus 2. I do not have planter fertilizer units so broadcast all P and K. Would like to get the low spots up to snuff, but so spotty sample to sample, that I am not sure it is possible to map accurately for variable rate application. Also the low P and low K spots are mostly uncorrelated with each other, so would require seperate application trips. Considering just broadcasting replacement rate, but wondering if anyone has dealt with a similar situation or has a better idea.

Re: What to do, what to do
Thanks Shaggy. That is what I am going to do with the lime recommendations. The co-op has a VRT spreader and the soil test ph changes follow the contour lines and soil type changes rather nicely. The P and K changes however, seem to be random and I am guessing that if I move 50 feet in any direction from where the probes were taken the readings would likely change by over 30%.
