The granules (1) are each comprised of a coated core (2), and are characterized in that the coating is comprised of two layers (3, 4), the layer closer to the core (first layer) not providing by itself around the core (2) a unique layer, autonomous and/or capable of keeping its properties, and the layer situated immediately after (second layer) being a protection layer. As an example, the core (2) is comprised of a natural or artificial seed, and a first layer is comprised of beneficial microorganisms such as bacteria and fungi. The granules may be used particularly for the introduction in substrates and soils, particularly for regenerating them, of granules containing bacteria and/or fungi which are beneficial for plants, to provide microbiological fertilizers for plants, to obtain natural or artificial seed coated by bacteria (bacterisation) and/or beneficial fungi (fungisation), or coated by substances which stimulate or delay germination.
