  • Fertilizer/plant vitalizer
    Patent number: 7592465
    Abstract: Contamination by microorganism of an aqueous proline solution is prevented by adjusting a proline concentration of the solution to 20% (W/W/) or more. Such solutions are useful as fertilizers and/or plan vitalizers. Preservation of the novel solutions are possible over a significant period of time, allowing for more flexibility in the distribution and application of commercial products made from the solutions.
    Type: Grant
