Hi Rodger,
To tell you honestly I don't know how the lab tested tge soil. What they did ask for though is that I get soil samples from all 4 corners of the plot of land and mix them. They took about a 1-2 kg sample of soil and ran their tests.
I don't think there would be a data integrity issue, I just want to make sure that extra molybdenum won't negatively affect the kiwiberries I do plant next spring.
