For $14, you get 7 data points. For $11 more, you can get that and the other 14 missing tests @ Midwest Labs
What's missing:
Base saturation K
Base saturation Ca
Base saturation Mg
Base saturation H
Base saturation Na
Copper
Boron
Sulfur
Manganese
Excess Lime
Sodium PPM
Buffer pH
Zinc
and they don't tell you what kind of phosphorus number they're giving you.
Granted, if you're not gonna use all the info, it doesn't pay to get it. But if you're after a proper lime recommendation or fertility recommendation, you need those base saturation numbers and your buffer pH. Sulfur and boron can tell a story even if you don't plan to address them as well.
