Abstract:
1. A method of irrigating soil comprising: combining additives with an aqueous fluid to create a treated irrigation water, wherein the additives comprise a preselected amount of a non-ionic surfactant in an amount as low as about 0.0000057% by weight and a preselected amount of a displacement ion in an amount ranging from about 0.00002% to about 0.03% of the displacement ion by weight in addition to the amount of any other displacement ion present in the aqueous fluid before the combining; and, applying the treated irrigation water to a soil for an improved penetration of water into the soil during the irrigation, wherein the improved penetration is obtained through a constant, or substantially constant, application of the treated irrigation water to the soil during the irrigation; and, wherein, the penetration of water into the soil during irrigation is improved over processes that do not apply (i) the non-ionic surfactant in an amount as low as about 0.0000057% by weight and (ii) the displacement ion in an amount ranging from about 0.00002% to about 0.03% by weight using the constant, or substantially constant, application; and, the application is substantially constant when a brief interlude in the applying of the treated irrigation water does not significantly affect the improved penetration of the water into the soil.
