NW Iowa | Nothing wrong with trying a differant lab. I would take more tissue samples same day same time and ship off to the different labs. If they both come back low then you know it s not the lab. As for testing one sample doesn't do much for me. If I get 5 or more tests saying the same thing then it's worth looking at.
If it really is deficient then the manganese is getting tied up with something in the soil. If that's the case I would band it next to row and test that to see what happens. | |
