FormulaMixture moisture wet basis = 100*(a*ma/100+b*mb/100+water)/(a+b+water); Dry solids mass = a*(1-ma/100)+b*(1-mb/100)

How to use this tool

  1. Enter ingredient a wet mass, ingredient a moisture, ingredient b wet mass, ingredient b moisture, and added water in the displayed units.
  2. Calculate and use each labeled result for compost moisture mixing balance. Compare the result with a measured sample before committing materials.

{
  "a": 20,
  "ma": 70,
  "b": 10,
  "mb": 20,
  "water": 2
}

Accuracy and scope

Mass balance only; ingredient moisture must be measured or estimated. Does not assess pathogens, maturity, aeration or suitable compost conditions.
