Which type of spreader applies uniformly sized dry particles to various surfaces for precise application?

The choice of a drop spreader or gravity spreader is indeed the correct answer when considering the application of uniformly sized dry particles for precise application. This type of spreader operates by allowing material to fall straight down through a series of openings as it is pushed or pulled across a surface. The result is a direct deposition of the applied material in a consistent and controlled manner.

This precision is particularly beneficial for applications such as grass seed, fertilizers, or other granular products that require even distribution to promote healthy growth and minimize waste. The drop mechanism ensures that the material lands only in the intended area, which is critical for targeting specific patches of lawn or flower beds without overspreading or risking application to unwanted areas like sidewalks or driveways.

In contrast, other types of spreaders may not provide the same level of accuracy. Broadcast or rotary spreaders, for example, distribute material in a fan shape, which can lead to uneven coverage if the spreader is not calibrated or operated correctly. Hand spreaders, while convenient for small areas, generally lack the ability to apply material uniformly over larger spaces.
