Guidance for calibrating an 800-gallon hydroseeder to apply Profile® mulches and Biotic Soil Media™ at specified rates. Tables outline mulch mix rates, load sizes and area covered per tank for HP-FGM®, ET-FGM™, BFM, EFM™, Base Mulch and Biotic Soil Media™ using centrifugal or gear/positive displacement pumps. Step-by-step instructions explain how to calculate and stake a calibration rectangle, then apply slurry evenly from two directions to achieve the desired pounds-per-acre coverage and a clear visual reference. Users are reminded that final determination of suitability and use is the sole responsibility of the user.
Key Points
- Provides application rates, mulch mix rates and tank coverage for multiple Profile hydraulic mulches and Biotic Soil Media in an 800-gal (3,028 L) hydroseeder.
- Details a nine-step calibration process, from selecting an application rate to loading the correct number of bales and spraying until the tank empties.
- Explains how to size and stake a calibration rectangle by using tank coverage area, slope length and calculated width.
- Emphasizes spraying slopes from two directions to help achieve more even hydraulic mulch coverage.
