  • Patent number: 11242293
    Abstract: A biofertilizer is disclosed that include specific formulations of algae biomass and a mycorrhizal fungus. This biofertilizer may be a useful way of utilizing algae biomass created for carbon sequestration purposes for a productive agricultural purpose. The combination of algae biomass and mycorrhizal fungus may provide advantageous effects to a crop, as the algae may be a nutrient source for both the crop itself and also for the mycorrhizal fungus that allows the fungus to grow and form a mycorrhizal relationship with the root system of the crop. The biofertilizer may be pelletized with rice hull filler and have a specific range of moisture content, so as to be compatible to agricultural fertilizer delivery equipment. Methods of manufacturing the pelletize biofertilizer are also provided.

The silver compound is silver nitrate, silver acetate or silver phosphate; the primary amine is methylamine, ethylamine, monoethanolamine, tris(hydroxymethyl)aminomethane, 2-amino-2-methyl-1,3-propanediol, 2-amino-2-ethyl-1,3-propanediol, .alpha.-aminooxyacetic acid or aminoethoxyvinylglycine; and the nucleic acid-related substance is nucleic base, nucleoside, nucleotide, oligonucleotide, polynucleotide, purine derivative or pyrimidine derivative.The present freshness retentive for cut flowers demonstrates an extremely excellent effect on cut flowers highly sensitive to ethylene, e.g. carnation, Gypsophila elegans, sweet pea, etc., as well as on cut flowers low sensitive to ethylene, e.g. chrysanthemum, rose, orchid, etc., for their freshness retention.
