Excerpt from The Reclamation of Alkali Soils

However, counteracting forces are often present. For example, if the soluble salts which accumulate in the soil or are applied as constituents of the irrigation water are composed in considerable part of calcium compounds, the adverse chemical and physical edects just alluded to fail to materialize to any great extent. Under such conditions soluble salts do not produce excessive chemical changes in the clay and humus of the soil.' Where this is the case, mere drainage and leaching will suffice to produce complete reclamation of the soil. An example of this type of soil condition is found in the Imperial Valley. As Thomas) has shown, the excessively saline soils of certain parts of the Imperial Valley can be reclaimed readily and be caused to produce large yields of crops by the simple expedient of drainage and leaching without applying any chemical treatment whatever. These soils contain relatively large quan tities of soluble calcium salts as well as large amounts of sodium salts.
