Hydroseed Slurry Mix and Tank Count
Seed, mulch, and tackifier solids for a hydroseed job and the tank loads to shoot it.
Example
You enter
- Area to hydroseed (acres) 3
- Seed rate (lb/acre) 5
- Mulch rate (lb/acre) 2000
- Tackifier rate (lb/acre) 50
- Hydroseeder tank capacity (gal) 3000
- Max solids loading (lb/gal) 0.4
You get
- Total slurry solids 6165
- Tank loads to shoot 6
Details, formula, and sources
solids = area x (seed + mulch + tackifier rates), tanks = ceil(solids / (tank gallons x loading limit)). A 3-acre stabilization at 2,000 lb/acre mulch is 6,165 lb of solids, 6 loads in a 3,000-gallon tank. The mulch rate (set by the slope) dominates; distinct from agricultural seed-rate.
seed_lb = area_ac x seed_rate_lb_ac; mulch_lb = area_ac x mulch_rate_lb_ac; tackifier_lb = area_ac x tackifier_rate_lb_ac; total_solids_lb = seed_lb + mulch_lb + tackifier_lb; tanks = ceil(total_solids_lb / (tank_gal x max_load_lb_per_gal)).
Slurry loading identity by name (per-acre solids over the machine loading limit); first-principles arithmetic.
The slurry loading takeoff is public hydroseeding practice; the rates come from the spec or agronomist.
Estimate. AHJ and licensed professional govern.
