Scale build-up on the surface of the soil forms a barrier and prevents the water from seeping down into the root system of the plants and causes much of the water to remain on the surface where it evaporates before it is able to soak into the ground. Since the water flowing through the Sidon Integro™ is free of scale crystals, there is no buildup of scale on the ground surface and the water permeates quickly into the soil, carrying nutrients to the roots effectively.
