pH Determination (Silage Only) in Feed and Forages

  1. Fill a 150 mL beaker half full with fresh silage and add sufficient water to set sample leaving about 1/2 inch of free water over the top.
  2. Stir and let stand 30 minutes.
  3. Stir and remove the water from the silage by pouring into another beaker.
  4. Read the pH of the solution immediately using a calibrated pH meter and buffers, pH 4.0 and pH 7.0. Record value with one decimal.
