RETROSAL®

SOIL CONDITIONER

GENERAL INFORMATION

Organic acid mixture characterized by a high level of carboxylic groups, which is able to attack and
render the calcium carbonates present in the soil soluble.
Calcium let off and carried by RETROSAL substitutes sodium in absorption complex so that
sodium itself passes in solution and it is washed away. So RETROSAL reduces sodium content in
soil and, meantime, meliorates its chemical and physical properties (structure, aeration, cationic
exchange capability etc.). The presence of Zinc promotes root system development and it
increases resistance to conditions of salinity.
