1. A process for preparing a composite of porous material/compound/hybrid organic-inorganic material having a 2:1 lamellar structure, said hybrid material having the following general formula I:
Nax[(Mg3)(Alx(RSi)4−x)O8+x(OH)2]  (I)
wherein
x is a number such that 0≤x<1.2 and
R represents a C1-C30 alkyl group, an aryl group, a (C1-C30 alkyl)aryl group or an O—(C1-C30 alkyl) group, the alkyl group being optionally substituted with at least one substituent selected from phenyl, vinyl or mercaptopropyl,
and said compound being selected from the group consisting of at least one active substance and at least one microorganism and mixtures thereof,
the process comprising:
a) the step of sol-gel synthesis of the hybrid organic-inorganic material having a 2:1 lamellar structure in the presence of the compound and of the porous material saturated with the compound; and
b) the recovery of the composite,
wherein the silicon source required for the synthesis of the hybrid material of formula I of step a) is an organoalkoxysilane or a mixture of organoalkoxysilanes having the following general formula II: RSi(OR′)3 (II);
wherein R′ is a methoxy or ethoxy group.
 
14. A composite of porous material/compound/hybrid organic-inorganic material having a 2:1 lamellar structure of formula (I), obtained by means of the process as claimed in claim 1.
 
20. A method for the fertilization, nutrition, growth stimulation and/or prophylaxis of plants and/or the improvement of the physical, chemical and/or biological properties of the soil or of the culture substrate of plants comprising the administration of an effective amount of the composite as claimed in claim 14, or of a composition comprising the composite as claimed in claim 14 and an excipient, to a plant in need thereof or to the soil or culture substrate of a plant in need thereof.
