Promi-Sal® Extra contains calcium salt of polihydroxycarboxylic acid (PHCA) in its formulation. It is the best solution when used for irrigation with saline water, excessive salts from previous fertilizations, or naturally saline-sodic soils. Furthermore, Promi-Sal® Extra promotes soil flocculation, counteracting the dispersing effect of sodium ions. Through these aggregates, air, water, or roots can easily penetrate, giving the soil a structure suitable for high-yield production. This is critical in soils with low organic matter levels, where the soil is highly unstructured, and the availability of water and nutrients for absorption is less than optimal
