What is the primary function of a blower type spreader?

The primary function of a blower type spreader is to release granules into a blast of air. This method effectively distributes granular fertilizers, seeds, or pesticides across a designated area. The blower creates a stream of air that propels the granules, allowing for even and efficient coverage over large surfaces. This method is particularly useful in situations where precise application is necessary, as it can help avoid clumping and ensure that the material is spread uniformly.

In contrast, the other options focus on different functions that are not applicable to a blower type spreader. Releasing liquid pesticides in a fine mist pertains more to spray equipment designed for liquid application, while collecting soil samples and measuring soil moisture levels are associated with different tools specific to those tasks. Thus, the function of a blower type spreader aligns strictly with the dispersion of solid materials using air for optimal coverage.
