These granules 1, each constituted by a coated core 2, are characterized in that the coating comprises two layers 3, 4, the one which is closest to the core (first layer) not providing by itself around the core 2 a single layer, autonomous and / or capable of retaining its properties, and the one immediately after (second layer) being a protective layer. By way of example, the core 2 consists of a natural or artificial seed, and the first layer, of beneficial microorganisms such as bacteria and fungi. The granules can be used in particular to introduce into the substrates and into the soils, in particular to regenerate the latter, bacteria and / or fungi which are beneficial for the plants, to constitute microbiological fertilizers for the plants, to obtain natural seeds or artificial coated with bacteria (bacterization) and / or beneficial fungi (fungization), or by substances which stimulate or delay germination. |
