Abstract
A liquid fertilizer adjuvant composition is provided that includes a fertilizer, a pH buffering agent, a surfactant, and one or more color indicator that produce a first color change that indicates when an pre-selected first level of field treatment has been achieved. The composition is provided as a single solution. A second color change occurs when a pre-selected second, higher level of field treatment is required. The color change indicative of a pre-selected pH, water hardness, or a combination of both. The composition is particular well suited for inclusion of a urea fertilizer.
