  • 4c – improves the milk yield


area of focus: fermentation

harvest international pH: pH, days of fermentation
  • dominant, homofermentative lactic acid bacteria
  • fast production of lactic acid in order to rapidly lower the pH
  • low sugar consumption, preserves nutrients
  • better digestibility of organic substances
  • high palatability, improves feed intake

Usage recommendations

  • wet grass silages
  • protein plants (clover, lucerne)
  • late cuts of grass in autumn (low sugar)

Application: Apply harvest INTERNATIONAL® pH with 1.5 g per tonne of forage.

Usage instructions

Dissolve the freeze-dried powder in a sufficient amount of water and apply evenly over the forage using the suitable amount of water for your applicator.
The mixed solution should be used up within 48 hours.
