Two pails were filled with sand excavated from
the same location. Bermuda Tif
419 sod was cut from the same golf green and was placed on top of
the sand. Equal numbers
of drain holes were drilled in the bottom of each pail and equal
amounts of water were provided daily to each pail.
The pail on the left received an application of ACT.
The test began on 19 May and ended almost five months later
on 13 October. |

On completion of the test the sod samples were
removed from the sand. Every
attempt was made to protect the root structure of both samples.
This was made easier by using sand rather than sod.
This picture shows the difference ACT treated sample on the
left and the untreated sample on the right.
The treated roots were more than twice as long as the
untreated root sample. |
