I 've used Timberleaf for years. I think they contract with A&L for their
lab work. You can get the same data by just submitting a soilsa mple to A&L
and getting the results.

Where I've found Timberleaf to be superior is in their reccomendations.
They list what you need to add and how much. They also include a whole lot
of information on soil management. All their reccomendations are acceptable
for organic certification. The only trouble I have ever had with
certification was a certifying agent who saw that I was adding Boron and
knew it was on the "Resricted" List. I explained to him that use was
restricted (not prohibited) because Boron can supress plant growth at low
concentrations. I showed him my test results and recs. from Timberleaf and
I think he understood.

Here's the list of what they test for and their website:
Basic Soil Test: Tests for Organic Matter, Estimated Nitrogen Release,
Reserve Phosphorus, Available Phosphorus, Potassium, Magnesium, Calcium,
Hydrogen, Sulfate Sulfur, Soil pH, Buffer pH, Cation Exchange Capacity,
Soluble Salts and Sodium, Percent Base Saturation for Potassium, Magnesium,
Calcium and Sodium.
Includes a copy of our Supplemental Guide to Soil Management.
Trace Mineral Soil Test: Tests for Zinc, Manganese, Iron, Copper and Boron.
