Solution preparation and dosing
Aluminium sulphate is especially recommended for silage storage, therefore it can be fed to the dosage point in dry form or as a solution, by means of a continuous solvent. Aluminium sulphate is recommended to be dissolved in a 5-20% solution for continuous preparation and 5-40% for discontinuous preparation.
Aluminium sulphate is slightly hygroscopic, and it should be stored in a dry place. The product is stable for at least one year when packed in bags. When the solid aluminium is dissolved, the storage recommendations for liquid aluminium sulphate are followed.
