| | WQWM-152 : Water Quality Sprayer and Spreader Calibration |
 | | Rotary spreaders have distribution patterns that are more forgiving of operator error, require a lower push effort, have better ground clearance, and have less delicate rate mechanisms, allowing them to hold their calibration longer over time. |
 | | Drop spreaders have uniform and consistent patterns, low drift potential, and precise control of the edges of the patterns which is useful for edging around small areas such as driveways and flower beds or near environmentally sensitive areas such as ponds or streams. |
 | | Unlike the drop spreader, some overlap of the pattern will be required to achieve a uniform distribution of the material, due to the bell-shaped nature of the distribution pattern of the rotary spreader. |
