Turf-Tec Penetrometer Applications

GOLF GREENS

When the Penetrometer is used in mid-moisture range of soil, 50% compaction

appears to be the average for good golf green soils. New USGA greens or

greens being top dressed with sand will average slightly higher, or nearer 60%

compaction. These are generalities and compaction percentages may run higher

or lower on your greens. Each green should be analyzed in relation to

playability. If a green plays well, compaction levels should be recorded for that

particular green. Subsequent readings with your Turf-Tec Penetrometer will then

show deviations from the norm. Often consistency from one green to another

green is more important then actual percentages as all greens will play and react

with the ball the same way.

DRY SPOTS

Dry spots can be detected before they cause wilting. They can be detected

visually when grass turns a bluish or purple, and when foot prints are visible on

the turf surface. To confirm that a dry spot is starting to form, the Turf-Tec

Penetrometer will register the difference in penetration.

LAYERS

Layers of sand, peat or thatch will be evident from wide fluctuations in depth

readings on the scale. Soil compaction layers, usually found in the two to four

inch zone will be evident on the scale. Rocks or stones will, of course, be quite

evident on the scale.

SURFACE COMPACTION

Perimeters of greens, walk-off areas, and cupping areas may show more

compaction than the rest of the green. These areas can be spot aerified with the

Aeriforke or mechanically aerified with a powered machine, without doing the

whole green.

ATHLETIC FIELDS AND OTHER SPORTS AREAS

These areas should be monitored with the Turf-Tec Penetrometer in relation to

the intensity of use.

FOOTBALL FIELDS

Readings should be made and recorded at each ten yard line from end to end

and at least four from side to side in each ten yard area.

BASEBALL FIELDS

Random readings should be made on the infield and outfield recorded and

compared to detect the development of problems.

OPEN PLAYFIELDS AND OTHER SPORTS TURF AREAS

Record Turf-Tec Penetrometer readings on the soils of each area. At least nine

readings should be taken (three on each side and three down the center).

Compare on regular monthly intervals.
