I have tissue and soil sampled over 2500 corn fields the past 20 years and collected yield data on these fields. We had the tissue tested for N%-P%-%K-S% and NO3 N ppm and have found no correlation between tissue sample results and yields unless there actually is a deficiency except for NO3-N there is trend of yields going down as NO3-N increases.
