Definitions
- the present invention refers to fertilizing compositions comprising inorganic particles of a substituted and surface functionalised calcium phosphate compound; to fertilizing compositions comprising inorganic particles of a substituted and possibly surface functionalised calcium carbonate compound and to processes for preparing the aforementioned fertilizing compositions and inorganic particles.
- the invention refers to fertilizing compositions that have preferred but not exclusive use in foliar fertilization for applications in farming and gardening.
- the nutritional elements essential for the growth and development of plants are taken from the environment, meaning atmosphere-water- earth.
- the atmosphere which is the main source of nutrition for plants since it provides carbon dioxide (CO2). CO2 is assimilated mainly during photosynthesis and carbon and oxygen together constitute about 90% of the dry matter of the upper plants.
- the atmosphere also provides oxygen (O2), presiding aerobic respiration, a substantial amount of nitrogen (N2), traces of gaseous ammonia (NH3) and sulphur dioxide (SO2), also assimilable by some plants.
- Water (H2O) is the second source of nutrition for plants. Although most of the water absorbed by the roots evaporates through transpiration from the leaves, a small fraction is used as reactant in metabolic transformations.
- the earth constitutes the third source from which plants obtain the nutritional mineral elements, deriving from the breaking up and solubilisation of the bedrock and from the breaking down of animal and vegetable residues.

- foliar fertilization being a technique of administering fertilizers that exploits the ability of plants to absorb water and the mineral salts dissolved in it through the epidermis and the stomata of the leaves, can be considered like a supplementing intervention that allows nutritional deficiencies to be solved for the main macro and micro elements, nutritional elements thus defined based on the fact that the former are absorbed in relatively higher amounts than the latter.
- the macro elements can include nitrogen, potassium, phosphorus, calcium, magnesium and sulphur.
- the micro elements can include iron, chlorine, sodium, zinc, copper, boron, manganese and molybdenum.

- the fertilizers used contain nutritional elements in a form not assimilable by the plant, and therefore such products actually are unable to make up for the nutritional deficiencies of the plants.
- the main foliar fertilizers on the market are based on the presence of molecules that cannot be degraded by the soil (like for example EDTA, EDTHA and chelates in general) that are used to promote the entry thereof inside the plant, but at the expense of the health of the farmer/gardener, of the plant and of the earth since they are potentially toxic molecules.

- nutritional micro and macro nutritional elements can thus be present both internally in the particles of the inorganic carrier (whenever at least one metallic ion M selected from the group comprising Zn, Cu, Mn, Mg, Mo, Fe, K, Se is present in the structure of the particle), and externally.
- this substitution/functionalization leads to a controlled release of the nutritional elements that will thus be released in sequence as well as in a form favoured and assimilable by the plant itself.
- the fertilizing compositions in accordance with the invention advantageously have a double release kinetics of the micro and macro elements.
- the particles of calcium phosphate compound initially release the micro and macro elements externally bonded to them, directly or possibly through the organic compounds containing at least one hydroxyl group, whereas, while they are present on the leaf surface they release the micro and macro elements contained inside the particles themselves more slowly.
- the surface functionalization of the particles of calcium phosphate compound leads to a controlled release also of the at least one organic compound containing at least one hydroxyl group that will thus be released in a form favoured and assimilable by the plant itself, performing its action as well as it can.

- the X-ray diffraction spectrum highlights a crystalline material that has the diffraction maximums characteristic of a calcium phosphate (Example 1).
- the diffraction maximum of the calcium phosphate obtained in this example are as follows: 2 Theta 26 - 32 - 33 - 34.
- the morphological analysis by Scanning Electron Microscope shows that the particles of calcium phosphate have crystalline formations of micrometric dimensions, comprised between 0,2 micron and 2 micron.
- the X-ray diffraction spectrum highlights a crystalline material that has the diffraction maximums characteristic of a zinc and calcium carbonate (Example 2).

- the morphological analysis by Scanning Electron Microscope shows that the particles of carbonate have crystalline formations of micrometric dimensions, comprised between 0,2 micron and 1 micron.
- Solution 2 was then added to solution 1, by dripping, at a flow equal to 0,2 L/min.
- the synthesis product was aged inside the reaction environment, keeping it under stirring, in thermostated environment, for a total time equal to 10 hours.

- the resulting suspension was then kept under agitation for 45 minutes.
- the suspension of particles of calcium phosphate surface functionalised with micro and macro elements obtained was then used to produce fertilizing compositions according to the invention.
- Solution 2 was then added to solution 1, by dripping, at a flow equal to 0,125 L/min.
- a fertilizing composition according to the invention was made by mixing 70 g of the aqueous suspension of Example 1 with 30 g of the aqueous suspension of Example 2. In this way 100 g of fertilizing composition are obtained .
- the SEM image of figure 5 shows how the foliar distribution of a conventional copper-based product is not very capillary on the foliar wall itself and how the rough dimensions of a conventional product (a sing le particle is visible in the high part of the SEM image) do not allow homogeneous coverage of the leaf.
- the plants treated did not show attacks from the disease (peronospora), but with respect to the conventional treatment defined above, one third of the copper was used, which however conveyed through the formulation described in example 3, allowed it to be much more functional (despite the low dose) actually obtaining comparable results to a conventional treatment, containing a greater amount of copper.
- the SEM image of figure 6 shows how the foliar distribution of a product made according to example 3 is much more capillary and the product is much better distributed over the entire foliar wall examined as highlighted by the numerous particles visible on the leaf and distributed evenly on its surface.
- the use of a fertilizing product according to the invention gives the plant the nutritional elements that it needs, avoiding overdoses and obtaining homogeneous distribution of the product on the foliage and optimal foliar adhesion.
