Abstract
The present invention relates to a method for encapsulating a compound selected from the group consisting of at least one active substance, at least one microorganism and mixtures thereof in an organic-inorganic hybrid material of 2:1 lamellar structure, said material having the following general formula I: Nax[(Mg3)(Alx(RSi)4−x)O8+x(OH)2] (I) the method comprising: a) sol-gel synthesis of the organic-inorganic hybrid material of 2:1 lamellar structure in the presence of the compound; b) recovery of the compound encapsulated in the material of general formula I. It further relates to the compound encapsulated in an organic-inorganic hybrid material of 2:1 lamellar structure of general formula I, a composition comprising same and its use for fertilizing, feeding, stimulating growth and/or prophylaxis of plants and/or improvement of the physical, chemical and/or biological properties of the soil or of the culture substrate of plants.
