How can the rate of application with a hand-operated, granular applicator be increased?

The rate of application with a hand-operated, granular applicator can be effectively increased by adjusting the spread width. This involves modifying how widely the granules are dispersed from the applicator. When the spread width is increased, more area is covered per unit of time, thus enhancing the application rate.

Walking faster, while seemingly intuitive, does not necessarily correlate with a proper distribution of granules and can lead to uneven application. Walking slower would decrease the rate of application, which is contrary to the goal. Increasing the weight of the granules could impact the speed at which they are released but would not inherently improve the coverage or application rate. Therefore, adjusting the spread width is the most effective way to achieve a higher application rate with a hand-operated, granular applicator.
