Soil Set Summary Sheets – So

• Use R for research.
• If a test isn't in the Fee Schedule, put it in parentheses.
• For S20, S24, S42 tests, include the element symbol(s).
  When multiple parameters are requested for a test, list each test and its parameters separately.
  (See examples #9 and #10.)
• Sort the tests. (See example #9.)

1. County Routine: Leave blank
2. Research Routine: R S1
3. County Routine plus Organic Matter: S1 S6
4. County Routine + Heavy Metals: S2
   [S2 includes S1, so don't list them separately.]
5. Research CaST: R S1C
6. Research Sodium Nitrate: R (NaNO3)
7. County Greenhouse: S11
8. Research Greenhouse pH only: R S12
9. Research Trace Lab selenium, arsenic, and mercury: R S17 S42As S42Se
10. County carbon + nitrogen: S21

There are five methods under which we run soils:

• S1 test: Mehlich 1
• NH₄OAC: Ammonium acetate
• NaHCO₃: Sodium bicarbonate
• NaNO₃: Sodium nitrate
• SrNO₃: Strontium nitrate

Example: R (NH₄OAC)

The non-Mehlich methods are gaining popularity based on Dr. Sumner's research, but they're not in the Fee Schedule.

When logging in non-Mehlich soils, put the tests in parentheses, and use the symbols above. They'll generally be written like that on the paperwork, but NH₄OAC may sometimes be written like "Amm Acet."
