RaicoSil Hay

RaicoSil Hay is the first preservative for hay that contains a unique combination of salts of selected preservatives. Due to its special product formulation RaicoSil Hay is neither corrosive nor aggressive and is classified as a neutral salt. The use of acid-proof application systems is therefore not necessary. The dosage itself takes place during the pressing process, in the pickup of the press.



  • significantly shorter harvest timeslot (minus two days)
  • better quality
  • better hygiene status
  • lower losses (mechanical and non-mechanical)
  • Avoidance of the Maillard reaction (sugar and protein) (ADL)


Direction of use
