Description

Polisal Properties

• Polysal is a specialized compound for treating saline and alkaline lands with high calcium or sodium content.
• Polysal works to replace the calcium ion in the soil with sodium, and its absorption by the plant leads to the production of high-hardness fruits suitable for storage and handling for relatively long periods.
• Polysal works to break up the calcareous lands into individual carbonates and calcium. The carbonates combine with water to form carbonic acid. It lowers the acidity of the soil and releases calcium, which facilitates absorption by the roots of plants.
• Polysal contains polycarboxylic organic acids that increase the cationic capacity of soil particles. Sodium is freed and easy to wash with irrigation water.
