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.
