The SeedMaster Seed Rate Calculator will allow a grower to rapidly and effectively calculate a seed rate to achieve a desired plant population within a given field. It will also allow a grower to calculate how many pounds of seed that is required and the total cost associated.

Calibration Estimator is associated with SeedMaster machines that are controlled by the Raven Viper in-cab monitor. A “cal weight” number controls the rate of the granular metering system. Every granular product requires a calibrated cal weight number to allow the product to be metered at the desired rate.

The Cal Weight Estimator will allow a grower to receive an estimated calibration number for a specific product being metered, meter type used, and drill width. SeedMaster recommends that an initial calibration catch test be performed to ensure calibration accuracy. The purpose of providing this tool is to alert a grower of a potential error during the calibration process before unwanted field results can occur. This tool will be especially valuable for new operators or when new products are metered.

The Cal Weight Info Submission will allow growers to very easily and quickly send their calibration information to SeedMaster. This will allow SeedMaster to provide a more accurate estimated calibration number to all users of the App. Not only yourself will benefit in the future, but all users of the App. All submissions are reviewed by SeedMaster to ensure validity before becoming a component of the Cal Weight Estimator.

The Cal Weight Note Book is a grower’s own personal notebook with saved calibration values from his or her own specific machine(s). All Cal Weight submissions are automatically stored for the grower for future reference at any time
