Maybe spatial variables maybe you hit more bottoms las time and more slopes summits this time. Throw that out, and my question is are you sieveing the samples. Because your lab is probably not, and if you want accurate comparison you need to look at 2" samples over time.

What analysis is the lab using? Loss on ignition is affected by carbonates but is the quick and dirty they often use.
