Proser Ca


Quality and shelf life

Allowed in organic farming

PROSER CA is a specific product for the quality (color and dry substance) and shelf-life of the fruit. The calcium present is conveyed and completely assimilated thanks to the action of low molecular weight carboxylic acids. PROSER CA acts as an acidifier, improving the effectiveness of the products combined with it.


  • More storable, firm and compact fruits both on the plant and in the post-harvest;
  • Increased production, greater dry matter;
  • Greater strength of the plant, thanks to the high absorption and transmission of calcium;
  • Balanced development of the plant, due to the biostimulating action of the carboxylic acids;
  • Improvement of the effectiveness of combined products (fertilizers and/or pesticides), by acidifying the solution.
