EX TRAC TION PRO CE DURE

1. Fill a test tube (0755) to line 7 with *Universal Extracting Solution
(5173).

2. Use the 0.5 g spoon (0698) to add four level measures of soil to the
test tube. Cap and shake for one minute.

NOTE: When adding samples with high concentrations of
carbonates to *Universal Extracting Solution (5173), swirl tube to
mix for 30 seconds before capping to allow gases to escape.

3. Fold a piece of filter paper (0465) in half, then in half again. Press
corners together to form a cone. Place in funnel (0459). Pour
extract solution into funnel, collecting extract. This clear extract is
used for the test.

IRON TEST

1. Use a transfer pipet (0364) to add four drops of clear filtrate to a
large depression on a spot plate (0159).

2. Use the 0.05g spoon (0696) to add one level measure of *Iron
Reagent Powder (5275). Stir with a stirring rod (0519).

3. Use pipet (0392) to add one drop of *Ferric Iron Test Solution
(5116). Stir with a stirring rod (0519).

4. Match sample color to a color standard on the Ferric Iron in Soil
Color Chart (1348). Record as pounds per acre Ferric Iron.

IN TER PRE TA TION OF FER RIC IRON TEST

Most soils will contain iron in sufficient quantities to satisfy the needs of
most plants. A deficiency of iron is sometimes noted in alkaline soils,
and is indicated by a chlorotic condition of the plants. High tests may
be obtained on acid soils.
