formaldehyde-based polymer composite is coated on a surface of the biodegradable polymer fabric, and is embedded in meshes of the biodegradable polymer fabric. There is intermolecular hydrogen-bond interaction between the biodegradable urea-formaldehyde-based polymer composite and the biodegradable polymer fabric.

A bacterial product may comprise strains Azospirillum oryzae AO.sub.512, Azospirillum lipoferum AL.sub.20, Pantoea dispersa PD.sub.2, Bacillus subtilis TU.sub.2, Lysinibacillus sphaericus 3S and Paenibacillus polymyxa SR.sub.17, in a total minimal concentration of 10.sup.8 CFU/g (Colony forming Units). These bacteria may be attached to an insoluble granular carrier formed of a mixture of natural clays and minerals. This formulation may preserve the viability of the microorganism for a long time while in storage, as well as after its application on the field. These microorganisms, as PGPR, may be capable of fixing atmospheric nitrogen, solubilize phosphates, potassium, as well as other minerals immobilized in the soil, which allows for a drastic reduction, and even for a complete elimination, of conventional fertilization methods. These bacteria are not harmful in any sense neither to human beings nor the environment.

The present invention concerns 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:
Na.sub.x[(Mg.sub.3)(Al.sub.x(RSi).sub.4−x)O.sub.8+x(OH).sub.2]  (I)
wherein
x is a number such that 0≤x<1.2 and
R represents a C.sub.1-C.sub.30 alkyl group, an aryl group, a (C.sub.1-C.sub.30 alkyl)aryl group or an O—(C.sub.1-C.sub.30 alkyl) group, it being possible for the alkyl group to be substituted with a group chosen from a phenyl, vinyl, aminopropyl or mercaptopropyl group,
and said compound being chosen from the group constituted 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;
b) the recovery of the composite. It also concerns a composite obtainable by means of this process, a composition comprising it and its use in particular for the fertilization of plants.

Fire retardant and fuel decomposition compositions that include at least one compost accelerator, at least one deliquescent, at least one polymer, and at least one plant nutrient are provided. In one example, the composition includes at least one compost accelerator is in the range of 0.01-0.5 weight percent, at least one polymer in the range of 0.25-15 weight percent, at least one deliquescent in the range of 0.5-40 weight percent, and at least one plant nutrient in the range of 0.25-10 weight percent.

Agglomerated dispersible granules are disclosed including activated alumina particles and phosphate particles. The activated alumina particles have a porous structure and a plurality of electrically-charged binding sites disposed within the porous structure. The activated alumina particles and the phosphate particles are present in the agglomerated dispersible granules as distinct phases agglomerated together. A method for amending soil with buffered phosphorus is disclosed including physically blending and then agglomerating activated alumina particles with phosphate particles to form the agglomerated dispersible granules. The agglomerated dispersible granules are applied to soil with the activated alumina particles and the phosphate particles being present as distinct phases and the activated alumina particles being free of phosphate disposed within the porous structure. An activated alumina suspension is disclosed including activated alumina particles suspended as a dispersed phase in a continuous phase, the activated alumina particles having a particle size less than 200 μm.

The present invention relates to the technical field of fertilizer and soil conditioner production, and particularly to a regulating solution, fertilizer and soil conditioner for increasing Vitamin C (abbreviated as Vc, which is also known as ascorbic acid) content of plants as well as a preparation method therefor and application thereof. At the same time, the present invention also relates to a resource utilization technique of wasted liquid in the industrial production of vitamin C. The regulating solution is obtained by regulating the pH value of a wasted gulonic acid mother solution (a residue after evaporation of fermentation liquid from vitamin C industry) or/and 2-keto-L-gulonic acid solution by an alkaline solution, wherein a fertilizer regulating solution is obtained by regulating the pH value of the regulating solution to 3.0-9.0; and a soil conditioner regulating solution is obtained by regulating the pH value of the regulating solution to 2.0-10.0. The regulating solution obtained by the present invention and the fertilizer and soil conditioner prepared by using the regulating solution as a raw material can significantly increase Vc content of plants, and the effect can be found in all plants tested.
