ABSTRACT:
The disclosure is directed to methods of making and using a water treatment composition for improved water infiltration during irrigation of agriculture. These methods include combining additives with an aqueous fluid to create a treated irrigation water, wherein the additives comprise a preselected amount of a surfactant and a preselected amount of a displacement ion. The improved infiltration is obtained through a constant, or substantially constant, application of the treated irrigation water to the soil during the irrigation.
