| abstract |
The invention relates to a novel biological fertiliser, a method for obtaining same and the use thereof as a plant growth stimulator, said fertiliser comprising a pure culture of strain C3 of Pantie dispersal, a pure culture of strain M3 of Azospirillum brasilense and indole-3-acetic acid, all of which are immobilised in a single solid medium acting as a slow release system. The method includes the following main steps: culture of the microorganisms; immobilisation of the cells, nutrients and other substances in the medium; and a single fluid bed drying step which enables lower temperatures to be used and lower moisture contents to be obtained, thereby providing the fertiliser with greater stability. The action of the fertiliser commences upon contact with the plant. |
