What is a horn seeder primarily used for?

A horn seeder is primarily used for granule distribution, which makes it a valuable tool in agricultural practices, particularly for seeding and fertilizing crops. This device allows for even and precise application of granular materials, such as seeds or fertilizers, across a designated area. It is designed to accurately control the flow of granules, ensuring that they are distributed uniformly over the soil, which is crucial for optimal crop growth and resource efficiency.

Using a horn seeder can enhance the effectiveness of planting by allowing for better spacing between seeds and reducing waste. This method is advantageous when compared to other techniques, such as broadcasting, which may not achieve the same level of precision.

While other options like water application, herbicide spraying, or pesticide measurement serve important roles in crop management and pest control, they do not pertain to the primary function of a horn seeder, which is specifically focused on delivering granular materials effectively.
