Collect and weigh the material on the sheet.Measure the area covered as: distance x swath width.Operate the spreader over a large enough sheet of plastic, cloth, or paper, such as a painter's drop cloth, to capture all the material.Fill the hopper with material, at least half full.Select a setting for the spreader if available, use a manufacturer's recommendation as a starting point."Catch Sheet Method" Calibration Procedure: bags are required to treat an area and 3 bags have been used when half the area has been treated, something is wrong! Monitor application usage and treatment area during spreader operations to check calibration accuracy if ten 50 lb.Check for clogging clogging of openings in the bottom of the hopper is common when treating moist turf.Treat the strips at both ends of the area first this allows you to start in this strip and turn the spreader on/ off in this area.Avoid non-uniform spreading when turning always turn off spreader when turning corners.Avoid skips and excessive overlap only a slight overlap of the wheels is necessary.Walk at normal speed (5 ft per sec) a faster pace will result in a lighter application rate.Some basic 'rules for the road' are provided here along with calibration procedures for drop type spreaders. Always read manufacturer's directions for proper spreader operation and calibration procedures. The swath width of the spreader (the spreader hopper width) will vary with the model and make but may range from 22 to 42 inches or more. However, the calibration procedures are exactly the same for the single-pass and double-pass application strategy.ĭrop spreaders are uniform in the distribution pattern of granules across the swath width. The procedures outlined below are based on a calibration in which the material is to be applied in a single application. is reduced by half and the calibration rate is 2.5 lb. In our example, the recommended rate in order to apply 20-5-10 at 1.0 lb. If this strategy is used then the calibration rate is cut by half. ft.).Ī more uniform application can be obtained if the recommended rate is applied in two applications one half the rate is applied in one direction and the other half at right angles to the first as shown in Figure 1. (in this example when the calibration rate falls between 4.75 to 5.25 lbs. The spreader is properly calibrated when the calibration rate is within ± 5% of the recommended 5.00 lb. To achieve this desired N rate, 5.00 pounds of total material (TM) per 1,000 square feet needs to be applied. (1000 square feet is abbreviated as "M"). In the examples given below using different calibration methods a 20-5-10 fertilizer will be calibrated to deliver 1 pound of nitrogen (N) per 1,000 square feet.

Regardless of the material (fertilizer, seed, pesticides), spreader calibration procedures will be the same for any granular type material providing the material is free flowing. However, these recommended settings are "suggested" spreader settings and are a good starting point but should be validated by calibration

Most professional grade fertilizers and pesticides come with directions for calibration and recommended spreader settings.

The accurate application of lawn materials requires proper calibration of lawn spreaders of which there are two basic types:
