Knowing spread pattern and proper swath overlap is essential to reduce streaking that often occurs in application of granular materials. The UK Coverage Calculator is a simple online tool that calculates the optimum overlap for an applicator based on data collected through a common pan test. It allows the operator to visualize the spread pattern from the machine and know the proper swath width to use to minimize streaks of over- or under-application of granular material.
