摘要：A Microsoft Excel-based software was developed to help Extension professionals with spreader calibration. Small, turf-used ground spreaders as well as spinner-type spreaders used in row crop agriculture can be calibrated using this software. Spreaders used in aerial application of urea and seed rice can also be calibrated. The software calculates the most commonly sought information during a calibration such as: total swath, optimized swath according to coefficient of variation (CV), and application rate.
