Which type of spreader is known for its adjustable sliding gate for precise placement?

A drop spreader is specifically designed to deliver granular herbicides and fertilizers with accuracy due to its adjustable sliding gate. This gate controls the flow of the material as it falls directly down onto the soil or turf beneath the spreader. The precise placement provided by a drop spreader makes it particularly effective for ensuring even distribution in targeted areas, reducing the risk of product waste and minimizing the chance of applying herbicide to unwanted areas.

The adjustable feature allows applicators to customize the amount of product dispensed based on their specific needs and the width of the area being treated; therefore, it is especially useful when working near sensitive plants or in tight spaces where over-application could be detrimental. This capability enhances both effectiveness in weed control and environmental safety, aligning well with integrated pest management practices.

Other types of spreaders like rotary and broadcast spreaders apply materials more broadly, which may lead to less precise placement, and pneumatic spreaders typically utilize air pressure for dispersal, which can also contribute to less targeted application.
