Definitions
- Granulated solid fertilizer formulated with mineral clays, siderophores chelating agents, secondary nutrients and micronutrients
- the present invention relates to a granulated solid fertilizer composition
- a granulated solid fertilizer composition comprising as support material a mineral clay added with secondary nutrients and micronutrients such as calcium, magnesium, sulfur, iron, zinc, manganese, boron, copper and molybdenum. , being added in its soluble form to ensure assimilation by plants, in addition to the addition of Siderophores for the nutrition of crops of agricultural interest, where Siderophores are iron chelating agents, capable of sequestering this in the presence of other metals and reduce it in its form Fe 3+ to Fe 2+ , a much more soluble and usable form for plant nutrition.
- fertilizers has become indispensable due to the low fertility of most soils to achieve the high yields and good quality that are expected today, so making proper use of them is important for agriculture sustainable.
- the soils contain all the essential elements that the plant requires for its development and reproduction, but in most cases not in sufficient quantities to obtain high yields and good quality, so it is essential to add nutrients through fertilizers .
- yields will be increasingly low due to the gradual impoverishment of the soil due to the extraction of nutrients as a result of agricultural practice.
- An infertile soil produces less, has less vegetation cover and is more exposed to erosion.
- Mineral nutrients are those that have originated in the soil and have been divided into three groups: the major nutrients (Nitrogen, Phosphorus and Potassium), the secondary (Calcium, Magnesium and Sulfur) and the minor (Iron, Zinc, Manganese, Boron, Copper, Molybdenum, and Chlorine). This division is due to the quantities required by the plants but not the importance of the plants.
- the major nutritional elements are generally the first that, due to high levels of extraction by plants, show levels of deficiency in the soil; while secondary and minor are required in smaller quantities and their deficiencies are not so obvious but if very important to consider. Although they are required in small quantities, the lack of any of them would limit the growth of the plant even if it has all other nutrients in appropriate amounts.
- Iron plays an important role as a catalyst for chlorophyll formation reactions as it functions as an oxygen transporter and its deficiency causes a chlorosis in the leaves of the plant; In addition to being an essential element for virtually all living beings fulfilling important cellular functions such as DNA synthesis, respiration and free radical detoxification.
- Zinc is necessary for the synthesis of substances responsible for plant growth as well as enzyme systems such as dehydrogenases, proteinases and peptidases.
- Manganese's main function is to be part of a plant enzyme system. Copper is necessary in the formation of chlorophyll and catalyzes various reactions in the plant. Boron helps in the formation of roots and main stems, with magnesium, iron and copper increases plant support and strength against diseases.
- iron In nature, iron (Fe) is found primarily in the Fe 3+ form as part of salts and hydroxides of very low solubility, chemical forms that prevent its use by some living beings.
- the availability of this element is fundamental in the success or failure of pathogenic or symbiotic microorganisms to invade an organism or to colonize a given environment.
- many organisms that include bacteria, fungi and plants produce small molecules of high affinity for iron called siderophores that act specifically as chelating agents to sequester iron in the presence of other metals and reduce it to Fe 2+ , a way much more soluble and useful for nutrition.
- Bacterial siderophores have aroused great interest in recent years due to the potential they have for the biological control of fungi and phytopathogenic bacteria and for constituting a growth promotion mechanism in plant growth promoting rhizobacteria.
- the analogues of these molecules in plants known as phytosiderophores, also play a fundamental role in the assimilation of iron in plants.
- the importance of phytosiderophores has regained strength by virtue of the increase in salinity of irrigation waters and soil pH, resulting from the depletion of aquifer mantles that result in a reduction in iron availability.
- Document CN 103087960 refers to an antimicrobial inoculant formulated with Bacillus amyloliquefaciens FQS38.
- the antibiological inoculant is characterized by being able to carry out the colonization of tomato roots, promote its growth and contribute to the prevention and treatment of diseases.
- the antibiotic inoculant can secrete proteases, cellulase, siderophores, auxins, gibberellins and other antibacterial ingredients and growth promoters. This document does not affect the novelty and inventive activity of the present invention, since the main components used are different when using a bacterial inoculant only.
- the invention discloses a growth promoter of alfalfa based on the rhizobacterium MJM-11 and its application.
- a strain of Enterobacter ludwigii MJM-11 that can be applied in four different ways that includes the preparation of siderophores and the promotion of plant growth under saline-alkaline stress. This document does not affect the novelty and inventive activity of the present invention since the main components used are different when using a bacterial inoculant only.
- US 2011268818 refers to compositions comprising an NGAL lipocalin and a mammalian siderophore that are useful as chelators and iron donors.
- the invention also provides sideroforo compounds of mammals, in addition, treatment methods and diagnostic methods. This document does not affect the novelty and inventive activity of the present invention since the siderophores mentioned herein are of mammalian origin and use for the treatment and diagnosis of iron deficiency in mammals.
- US 4872899 refers to a method and composition for the treatment of chlorosis due to iron deficiency in plants through the use of hydroxamic acid siderophores.
- Siderophores of this type are specific iron chelants, produced by certain microorganisms grown in iron-free environments.
- the siderophore can be applied to the plant by a variety of methods, including by application in the soil, foliar spray or direct injection into the plant. This document does not affect the novelty and inventive activity of the present invention since the present invention relates to a composition whose support is mineral clays added with siderophores, secondary nutrients and micronutrients.
- Document WO / 2012/130221 refers to a long-acting agent against phytopathogenic microorganisms, especially fungi that is prepared on the basis of Bacillus amyloliquefaciens plantarum spores.
- Representatives of said taxonomic group have the ability to form at least ten different antimicrobial substances belonging to the families of dipeptides, lipopeptides, siderophores, polyketides and the group consisting of bacteriocins / microcins.

It has a hardness between 1.9 to 2.3 kg / cm 2 , enough to withstand subsequent handling, during preparation and mixing with other nutrients.
- the preparation conditions make the material support handling during preparation. When mixed with other nutrients, it has low dust degradation and also has the ability to be 100% soluble, a characteristic that allows it to reach the roots of plants. Siderophores Overview
- the siderophores act as iron solubilizing agents from mineral or organic compounds such as lactoferrin and transferrin in vertebrates. They are mostly low molecular weight peptides produced by microorganisms. The siderophores are synthesized and secreted to the extracellular environment, where they bind to iron and recover thanks to specific transporters. In Gram-negative bacteria this process is carried out thanks to an external membrane receptor coupled to an ABC type transporter. Once in the cytoplasm, iron must be released from the iron-siderophic complex, a process that is carried out by enzymatic degradation of the complex or by iron reduction.
- ferritins Due to its reactivity, iron is sequestered in various proteins of organisms such as transferrins, lactoferrins and ferritins. The first two are found extracellularly (in the fluids of organisms), while ferritins are part of the intracellular iron storage proteins. Ferritins are the primary iron storage compounds for most organisms and are found in animals, in plants (phytoferritins) and microorganisms (bacterioferritins). Bacterioferritins are found in both bacteria and fungi and differ from animal and vegetable ferritins in that they have a united heme group. In all these organisms Ferritins fulfill similar functions as sources of iron storage when cells grow in abundance of this metal, reserves that are used to lower levels of this metal.
- microorganism When a microorganism enters a host organism, whether pathogenic or symbiotic, it finds a favorable environment with access to virtually all the nutrients necessary for its growth except for one, iron. Iron, unlike other elementary sources for nutrition, such as nitrogen, phosphorus, potassium and other macro and micronutrients, is not freely available in host organisms, so it is an important limiting factor for the growth of microorganisms. It is known that one of the responses of host organisms to the attack of pathogens is the reduction of free iron by sequestering this metal in the ferritin molecules. This mechanism operates in both animals and plants, although a notable difference is that in the former the control of ferritin synthesis occurs at the translational level, while in plants it occurs at the transcriptional level.
- Microorganisms that inhabit a host organism in a pathogenic or symbiotic form can use the iron of the organism that hosts them extracellularly from transerrins, lactoferrins or hydroxides iron, or intracellularly from hemoglobin or ferritins.
- Microbial siderophores are molecules secreted by microorganisms under iron deficiency conditions to sequester iron from their environment.
- the siderophores are molecules of low molecular weight of 0.5 to 1.0 kDa, soluble in aqueous solutions at neutral pH that are synthesized by bacteria, mainly Gram negative, fungi, yeasts and some plants (phytosiderophores), particularly grasses and that act as specific chelating agents of Faith 3+ .
- the main characteristic of this type of molecules is that they have a high iron dissociation constant, which ranges between 1022 and 1055. The synthesis of these molecules increases when the microorganisms are in iron-limiting conditions.
- the high affinity of these molecules for iron facilitates the uptake of this metal from compounds such as ferric hydroxide and proteins from the host organism such as transferrin or ferritin.
- siderophores form a hexadentate junction center, since their chemical structure usually consists of three double ligands arranged around a central ferric ion ( Figure 1). Hexadentate siderophores form 1: 1 complexes with the ferric ion, so that the release of the ion is unlikely, thus decreasing its potential toxicity. Iron binding groups are included in a larger chemical structure that maximizes their efficiency. Depending on the nature of the group that mediates the union with the iron atom, the siderophores can be divided into three basic types: catechols, hydroxamates and - hydroxycarboxylates, although mixed type siderophores have been described that contain in their structure several types of binding groups.
- Clay minerals mostly phyllosilicates, whose physicochemical properties depend on their structure and grain size, very fine (less than 2 ⁇ ).
- the clays have a structure based on the stacking of oxygen and hydroxyl ion planes.
- the tetrahedral groups (Si0) 4 4 ⁇ are joined by sharing three of their four oxygens with other neighbors forming layers, of infinite extension and formula (S ⁇ 2O5) 2 " , which constitute the fundamental unit of the phyllosilicates. In them the tetrahedrons are distributed forming hexagons Tetrahedral silicon may be partly substituted by Al 3+ or Fe 3+ .
- These tetrahedral layers are joined to other octahedral ones of gibsite or brucite type.
- some Al 3+ or Mg 2+ may be substituted by Fe 2+ or Fe 3+ and more rarely by Li, Mn, Ni, Cu or Zn.
- the plane of union between both layers is formed by the oxygens of the tetrahedra that were not shared with other tetrahedra (apical oxygen) and by groups (OH) " of the brucitic or gibsitic layer, so that, in this plane, it remains a (OH) - in the center of each hex formed by 6 apical oxygen.
- the phyllosilicates can be designed by. two layers: tetrahedral more. octahedral and are called bilaminar, or by three layers: one octahedral and two tetrahedral, called trilaminar. The unit formed by the union of an octahedral layer plus one or two tetrahedral layers is called a lamina.
- trioctahedral Mg 2+ dominates in the octahedral layer. If only two thirds of the octahedral positions are occupied and the remaining third is vacant, it is called dioctaédric.a (Al 3+ is the dominant cation).
- the sheets are not electrically neutral from substitutions, some cations, for others of different charge.
- the load balance is maintained by the presence, in the interlaminar space, or space between two consecutive sheets, of cations (such as in the group of micas), hydrated cations (such as in vermiculites and smectites) or octahedrally coordinated hydroxyl groups, similar to octahedral layers, as in chlorites.
- The; unit, formed by a sheet plus interlayer is the structural unit.
- the most frequent interlaminar cations are alkaline (Na and K) or alkaline earth (Mg and Ca).
- the physicochemical properties derive mainly from: its extremely small particle size (less than 2 um), its laminar morphology (phyllosilicates), isomorphic substitutions, which give rise to the appearance of charge on the sheets and the presence of weakly bound cations in The interlaminar space.
- the specific surface or surface area of a clay is defined as the area of the external surface plus the area of the internal surface (if it exists) of the constituent particles, per unit mass, expressed in m 2 / g .
- Clays have a high specific surface area, very important for certain industrial uses in which the solid-fluid interaction depends directly on this property.
- Paligorskita 100-200 m 2 / g
- Cation exchange capacity can be defined as the sum of all the exchange cations that a mineral can adsorb at a given pH. It is equivalent to the measurement of the total negative charges of the mineral.
- the first type is known as a permanent letter and accounts for 80% of the net charge of the particle; It is also independent of the conditions of pH and ionic activity medium.
- the last two types of origin vary depending on the pH and ionic activity. They correspond to crystalline, chemically active edges and represent 20% of the total sheet load.
- the siderophores present in the composition of the present invention act as iron chelating agents (Fe), capable of sequestering it in the presence of other metals and reducing it from its Fe 3+ to Fe 2+ form, a much more soluble and usable for plant nutrition.
- Fe iron chelating agents
- Clays such as kaolinite, smectite (montmorillonite), mica, hematite, talc and / or orthoclase are used in the present invention as support material, which thanks to their charges tend to bind when moistened. It is worth mentioning that the process of agglomeration (or granulation) is carried out in a pelletizing plate.
- clay mixed with zinc, manganese, copper and ferrous sulfates have a high agglomeration capacity
- a binder such as calcium hydroxide is essential to give the granule a greater hardness between 1.9 and 2.3 kg / cm 2 and make it not sprayed when mixed with other fertilizers and facilitate its application.
- the fertilizer has a low concentration of moisture (2 to 6%) which allows it to be mixed with hygroscopic fertilizers such as urea, even in a 1: 1 ratio without problems that may affect its physical characteristics.
- Another advantage that the developed product has is that thanks to the progressive dissolution of its components it allows it to act during a large part of the crop cycle; that is, upon contact with water the components gradually dissolve. Examples
- the formed granules are fed to a 3 section rotary kiln, heated by a burner that is fed with a mixture of hydrocarbons, predominantly methane. Inside the oven reaches a temperature of 100 ° C in the first section, which decreases to 57 ° C in the last section, to obtain a final humidity of the product about 3%.
- the fertilizer granules are then screened through the opening meshes 2.3 (mesh 8) and 4.0 mm (mesh 5).
- the product that passes through the mesh 5 and is retained in the mesh 8 is a product of 2.3 to 4.0 millimeters in diameter that will be ready to be packaged and distributed.
- the smaller sizes that cross the mesh 8 are fed back to the mixer and reprocessed. Larger sizes are ground and also reprocessed by feeding them back to the mixer.
- the granulated fertilizer obtained can be applied from 20-40 Kg / Ha in vegetables and grasses and 100-200 gr / tree in case of fruit trees. In soils where established crops meet low fertility levels and an alkaline pH.
- 150 kg of ferrous sulfate monohydrate, 29 kg of zinc sulfate monohydrate, 24 kg of copper sulfate pentahydrate, 42 kg of manganese sulfate, 54 kg of magnesium oxide, 132 kg of sulfate are mixed to produce one ton of the granulated fertilizer.
- the plate has a diameter of 1.8 m, with an inclination angle of 37 ° and rotates at 38 rpm, the mixture on the plate is sprayed with the mixture of water and calcium hydroxide with a flow of 1.25 lt / min.
- the granules formed they are fed to a 3 section rotary kiln, heated by a burner that is fed with a mixture of hydrocarbons predominantly methane. Inside the oven reaches a temperature of 100 ° C in the first section, which decreases to 57 ° C in the last section, to obtain a final humidity of the product about 3%.
- the fertilizer granules are then screened through the opening meshes 2.3 (mesh 8) and 4.0 mm (mesh 5).
- the product that crosses the mesh 5 and is retained in the mesh 8 is a product of 2.3 to 4.0 millimeters in diameter that will be ready to be packed and distributed.
- the smaller sizes that cross the mesh 8 are fed back to the mixer and reprocessed. Larger sizes are ground and also reprocessed by feeding them back to the mixer.
- the granulated fertilizer obtained can be applied in
