This guide supports accurate calibration of a 300-gallon hydroseeder for various Profile® hydraulic mulches and Biotic Soil Media™. It provides mulch mix rates, load sizes and coverage areas for HP-FGM®, ET-FGM™, BFM, EFM™ and Base Mulch at multiple application rates, plus Biotic Soil Media™ rates for centrifugal and gear/positive displacement pumps. Step-by-step instructions show how to stake a calibration rectangle, calculate slope width and apply mulch from two directions for uniform coverage. It notes, “To the best of our knowledge, the information contained herein is accurate… Final determination… is the sole responsibility of the user.”
Key Points
- Mulch mix rates, tank loads and coverage areas listed for HP-FGM, ET-FGM, BFM and EFM mulch products in a 300-gallon hydroseeder.
- Base Mulch calibration includes 50 lb (22.7 kg) per 100 gal (379 L) mulch mix rate and 3-bale or 150 lb (68.0 kg) loads with corresponding coverage areas.
- Biotic Soil Media™ calibration tables compare 75 lb and 100 lb per 100 gal mix rates for centrifugal and gear/positive displacement pumps with distinct coverage per tank.
- “Steps to Calibrate your Hydroseeder” outline selecting an application rate, calculating a calibration rectangle, loading the correct number of bales and spraying from two directions until the tank is empty.
