EC Nebraska | I don't have the links anymore, but I seem to recall that when Illinois redid the recommendations a few years ago, they found the P content varied widely across samples. Which seems to indicate that P removal per bushel may vary widely from field to field and region to region.
You would need to have samples from your farm tested to have any idea if they are accurate for your farming methods and soils. | |
