Agricultural practices are always under natural
disaster risks since farms are open areas to meteorological factors. These
risks can be classified as snow, hurricane, flood, tornado and frost. Frost,
one of the most important one of these risks, especially affects fruit gardens
and has a 30% of total damage in vegetable production. Till now farmers have
used to burn bales or plastic wheels to produce a heat cover in the gardens to
protect trees. Today more technological method of frost protection which is wind
machine is used to avoid frost. Wind machines are commonly used in Adana since
fruit gardens are so susceptible due to wide open gardens and often frost occurrences
in season changes. In this research 3 different make and model of frost
protector wind machines’ technical specifications and performances are
determined. According to the results it was found that two different power
groups of wind machines are commonly used. It was also determined that these
machines have protection radius of between 100 to 136 meters and protection
area between 3 to 6 hectares. According to the test results, the air flow has
an effect between 2 to 5 meters from the ground. The sound pressure levels of
these machines were over 85 dBA which is determined as the highest sound
pressure exposure level by ILO (International Labor Organization).
