Salinization is too much salt in the soil, blocking growth of plants.
In small trials Rebearth has shown to stimulate certain plants, like soy, to take up more Sodium from the soil. In this way de-salinization can take place, but it takes a long time to balance. Rebearth extends plant life on already saline soils. Causes of Salinization are sea level rises, artificial fertilizers and irrigation from wells and lakes.
