  • Formulation of phosphorus fertilizer for plants
    Patent number: 6896714
    Abstract: Concentrated phosphorus fertilizers are disclosed that comprise a buffered composition of an organic acid and salts thereof and a phosphorous-containing acid and salts thereof. The concentrated phosphorus fertilizers can be diluted with water of pH ranging from about 6.5 to about 8.5 at ratios of concentrate to water at about 1:40 to about 1:600 to result in a fertilizer having a pH in the range acceptable for foliar uptake of phosphorus.
    Type: Grant
    Filed: October 14, 2003
    Date of Patent: May 24, 2005
    Assignee: The Regents of the University of California
    Inventor: Carol J. Lovatt

  • Formulation of phosphorus fertilizer for plants
    Patent number: 6113665
    Abstract: Concentrated phosphorous fertilizers are disclosed that comprise a buffered composition of a phosphorous-containing acid or salt thereof. The concentrated phosphorus fertilizers can be diluted with water of pH ranging from about 6.5 to about 8.5 at ratios of concentrate to water at about 1:40 to about 1:600 to result in a fertilizer having a pH in the range acceptable for foliar uptake of phosphorus. Methods of supplying phosphorus to plants are also disclosed where the concentrated phosphorus fertilizers are delivered to plants and then sufficient water is applied to achieve a pH suitable for phosphorus uptake by the plant.
