Boom Sprayer Calibration

Calculations for boom sprayer calibration are tedious at best. This Boom Sprayer Calibration Spreadsheet was designed by Ron Patterson, Carbon County Extension Agent to help take the headache out of calibration calculations (for large boom sprayers (21-120 nozzles) download the Large Boom Sprayer Calibration Spreadsheet). There are five worksheets in the spreadsheet. The first contains instructions on how to use the spreadsheet. The second and third worksheets are to print so you can record the data collected in the calibration exercise--use the "Blank form oz." worksheet to record ounce collection data or the "Blank form ml." sheet to record metric collection data. The fourth and fifth worksheets are for entering data so the computer can do the calculations for you. Use "Formulas-oz." worksheet for ounce calculations or use the "Formulas-ml." worksheet for metric calculations.  Click on the link above to download the spreadsheet and then save it to your own computer for repeated use.
