This week's interesting observation: On our local potassium rate trial, we compared before and one-year-after soil test data to see if we could spot a correlation in soil ppm changes across our 0–260 lb potash rates.
Resampling the exact same spots a year later gave us a nice correlation: it took roughly 9.8 lbs of potash to move soil test K up 1 ppm. Small dataset on one soil type? Definitely. But it's always great observing real field data that makes sense.
