My experience is the test is pretty worthless. In a manure meeting a few years ago farmers shared their experiences using psnt and we all felt it was pretty useless as a whole. Best thing I have found is multiple years of testing on your farm with varying rates on nitrogen in side by side tests that run across about 10acres each to help take out field variability.
