Abstract: A fertilizer is provided to promote plant growth that provides needed nutrients to a crop at planting that has a depressed freezing temperature relative to conventional liquid fertilizers. The fertilizer has a first fertilizer product including a bio-available nitrogen source, a bio-available phosphorus source, and a bio-available potassium source that is blended with a second fertilizer product including an amount of ammonium acetate. The first and second fertilizer products being present in synergistically effective amounts, such that the coordinated amounts of the first and second fertilizer products give crop yields greater than a mere additive effect obtainable through the use of the respective first and second fertilizer products alone in the same amounts. The synergistically effective amounts of the first and second fertilizer products are directed to particular crops, and depend upon the crop in question, soil conditions, ambient weather, and other factors.

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.

Abstract: A water soluble liquid fertilizer concentrate is provided that includes a bio-available phosphorus source, said phosphorus source consisting essentially of a phosphite salt. At least one of a bio-available nitrogen source and a bio-available potassium source are also provided. At least one micronutrient of calcium, magnesium, cobalt, iron, manganese, copper, boron, zinc, or molybdenum is present in the concentrate as an aqueous solute or soluble chelates. In some embodiments, the at least one phosphite salt is present at between 30 to 57 total weight percent dissolved in water and optionally contains a phosphate salt. A process of fertilizing a crop includes diluting the fertilizer concentrate with water to obtain a liquid fertilizer solution. The liquid fertilizer solution is then applied to the crop and after by allowing sufficient time, the fertilizer solution promotes growth of the crop.
