Abstract (en)
[origin: CA3088222A1] The present invention relates to a process for encapsulating a compound selected from the group consisting of at least one active substance, at least one micro-organism and their mixtures in a hybrid organic-inorganic material having a lamellar 2:1 structure, this material having the following general formula: Nax[(Mg3)(Alx(RSi)4-x)O8+x(OH)2] (I), the process comprising the following steps: (a) sol-gel synthesis of the hybrid organic-inorganic material having a lamellar 2:1 structure in the presence of the compound; (b) recovery of the compound encapsulated in the material of general formula (I). The invention further relates to the compound encapsulated in a hybrid organic-inorganic material having a 2:1 lamellar structure of general formula (I), a composition comprising this compound and its use in plant fertilisation, nutrition, growth stimulation and/or prophylaxis and/or the improvement of physical, chemical and/or biological properties of the soil or a plant cultivation substrate.
