Agricultural Water Management | calSOL

Supplier: Organic Crop Protectants

Agricultural Water Management | calSOL can be injected into irrigations systems or applied directly to the soil.


Agricultural Water Management | calSOL contains a unique blend of organic polymers specifically developed to free-up Calcium (Ca++), Magnesium (Mg++) and Phosphate (PO4 3-) ions in soil and irrigation lines.


Agricultural Water Management | calSOL Technical Information

Problem: Saline Irrigation Water high in bicarbonates

Sodium ions (Na+) take up residence on soil cation exchange sites where Ca++ and Mg++ normally reside. As a result, calcium phosphate, calcium carbonate, and magnesium carbonate form insoluble salts and the soil turns sodic (sealed). Soil sodicity reduces the movement and uptake of water, air, and nutrients by plant roots.


Solution: calSOL

The introduction of calSOL soil balancing polymer makes calcium carbonate, calcium phosphate and magnesium carbonate “disassociate” (dissolve), releasing Ca and Mg ions so that they once again become available in soil solution. This also reduces calcium deficiency issues.

Also an excellent addition to lime and gypsum for rapid release of Ca and Mg.


Result: Sodium is Leached. Nutrient, air and water availability is restored

Mg and Ca ions become available displacing Na ions from soil particles. This makes the Na leachable and with further irrigation or winter rains Na is leached away from the root zone. Cation exchange capacity and soil porosity is restored and air, water and nutrient uptake by plant roots is optimised.


Grapes, Citrus, Stonefruits, Apples, Pears, Cherries, Avocados:
Meter 10 to 20 litres of calSOL per hectare in the first irrigation of a season prior to bud break.  Each irrigation during fruit formation meter 1 to 2 litres of calSOL per hectare. At post-harvest meter 2 litres of calSOL per hectare, every irrigation.
