Embodiment 1

[0209] Example 1 - Fertilizing composition comprising / having a glass substrate

[0210] A fertilizing composition comprising / with a glass substrate according to the invention was produced.

[0211] The raw materials used as precursors for the compounds present in the glass matrix are shown in the following table (Table 1), which also indicates the total weight of the mixture relative to the precursors used in the production process, expressed as The corresponding amount in percent concentration by weight.

[0212] Table 1

[0213]

[0214]

[0215] The ingredients were weighed and mixed together in the proportions shown in the table. The mixture of precursors thus obtained is sent to a melting system consisting of natural gas fired crucibles made of refractory material, suitable for melting up to 30 Kg of material at a time. The temperature is raised to about 1400° C. and maintained for several hours, ie until a homogeneous molten mass is obtained, which is fluid en...

Embodiment 2

[0220] Example 2 - Fertilizing composition in powder form comprising / having a glass matrix

[0221] The fertilizing composition obtained according to Example 1 was subjected to grinding by means of a system known in the art as a "high-pressure roller mill" using high-pressure grinding rollers until a powder was obtained with a particle size equal to 200 μm determined through a sieve. For the purposes of subsequent experiments, the fertilizing composition according to the invention in powder form was designated "FTZ001-M" ground fertilizing composition.

Embodiment 21

[0222] Example 2.1 - Combination of fertilization in powder comprising / with a glass matrix and also comprising citric acid thing

[0223] The fertilizing composition obtained according to Example 1 was subjected to grinding (as described in Example 2) and simultaneously mixed with citric acid in an amount of 2% by weight relative to the weight of the ground fertilizing composition.

[0224] For the purposes of subsequent experiments, the fertilizing composition according to the invention in powder form and also comprising citric acid was designated "FTZ001-MC" (ground fertilizing composition comprising citric acid).

Abstract

The present invention relates to a fertilizing composition comprising a glass matrix, wherein said glass matrix comprises: - at least three forming oxides, wherein said at least three forming oxides are SiO2, P2O5 and B2O3, and have a ratio by weight between SiO2 / P2O5 comprised from 1 to 5 and a ratio by weight between SiO2 / B2O3 comprised from 5 to 25; - at least one microelement; said fertilizing composition optionally also comprising citric acid and / or at least one humic substance. The subject matter of the present invention further relates to an aggregate comprising said fertilizing composition, at least one thickening agent and optionally at least one further microelement that is identical to or different from the at least one microelement present within the glass matrix of the fertilizing composition. The present invention also relates to a method for fertilizing herbaceous and / or arboreal crops which comprises administering said composition or said aggregate to the crops. Finally, the present invention regards the use of the fertilizing composition or of the aggregate comprising said composition to fertilize herbaceous and / or arboreal crops.

Description

technical field [0001] The present invention relates to fertilizers and in particular to fertilizing compositions comprising a glass substrate, aggregates comprising said fertilizing compositions and their use for fertilizing herbaceous and / or tree crops. current technology [0002] Over the past 70 years we have seen a real explosion in agricultural productivity due to the development and market availability of ever better performing machinery, plant protection products and fertilizers. At the same time, the continued growth in global food demand, the need to keep food prices low, the reduction in the acreage available for crops, and the need to grow crops and obtain products of high nutritional quality even in clearly unfavorable areas, have led not only to industrialized countries, but also to It has also led developing countries to switch to increasingly intensified agriculture. [0003] With respect to fertilizers, they are used to impart to the soil one or more nutrie...
