Colleges, private athletic field complexes, and other higher-end baseball fields need infield mixes that form a very firm playing surface, are free
of stones for player safety, and have minimal dust for player and fan
comfort.
The infield mix should contain higher amounts of silt and clay,
so it holds more moisture. It should contain a lower percentage of sand, which loosens the surface when dry.
The amount of maintenance your field receives, and the playability
expectations of its users help determine the right ratio of sand, silt,
and clay for your field.
Proper grading and maintenance of a
field is a must. No infield mix will perform properly if it is built
incorrectly or maintained poorly. However, choosing the right mix for
your level of play allows your field to meet its performance
expectations.
