Abstract
Description
Solución sobresaturada estable de fertilizante.Stable supersaturated solution of fertilizer.
La presente invención está relacionada con la aportación de nutrientes a las plantaciones vegetales mediante fertilizantes que se disuelven en agua para su aplicación, proponiendo un producto denso formado por una solución sobresaturada de un fertilizante, que permite una alta concentración con gran estabilidad.The present invention is related to the nutrient contribution to plant plantations through fertilizers that dissolve in water for application, proposing a dense product formed by a supersaturated solution of a fertilizer, which allows a high concentration with great stability.
Para favorecer el desarrollo y la productividad de las plantas es habitual el uso de fertilizantes, con los cuales se aporta un complemento de los elementos más necesarios para la nutrición de las plantas, existiendo para tal fin fertilizantes sólidos y fertilizantes líquidos.To favor development and productivity of the plants the use of fertilizers is habitual, with which a complement of the most necessary elements for the plant nutrition, existing fertilizers for this purpose solids and liquid fertilizers.
Los fertilizantes sólidos tienen el inconveniente de que son, generalmente, productos comburentes, lo que los convierte en mercancías peligrosas, resultando engorroso el transporte y la comercialización, por las normativas que se deben cumplir. Y además, el manejo en sacos de dichos fertilizante sólidos resulta complicado y costoso.Solid fertilizers have the inconvenient that they are generally oxidizing products, what which turns them into dangerous goods, resulting in cumbersome transport and marketing, by the regulations that must be comply. And also, the handling in sacks of said solid fertilizer It is complicated and expensive.
Por otro lado, los productos fertilizantes sólidos tienen en general una baja solubilidad y por lo tanto no se puede mezclar mucha cantidad de los mismos, por lo que su aplicación no permite inyectar muchas unidades fertilizantes.On the other hand, fertilizer products solids generally have low solubility and therefore do not You can mix a lot of them, so your application It does not allow injecting many fertilizer units.
Los fertilizantes líquidos existentes tienen también una baja solubilidad, debiéndose mezclar con gran cantidad de agua, de manera que para las cantidades necesarias de fertilización es necesario transportar mucha agua, encareciéndose el producto por el costo del transporte, lo que limita la rentabilidad del uso a zonas próximas a las fábricas de producción.Existing liquid fertilizers have also a low solubility, must be mixed with large quantities of water, so that for the necessary amounts of fertilization is necessary to transport a lot of water, making it more expensive product for the cost of transport, which limits profitability of use in areas close to the production factories.
Además, con los fertilizantes líquidos existentes en la actualidad, suelen aparecer cristales del producto base de los mismos con las bajas temperaturas, lo cual dificulta la inyección en las tuberías de riego para la aplicación.In addition, with liquid fertilizers currently existing, product crystals usually appear base of them with low temperatures, which makes it difficult to injection into irrigation pipes for application.
Los fertilizantes líquidos son soluciones de sales fertilizantes, de composiciones diversas y con niveles de disolución próximos al punto de saturación en agua. Se puede sobrepasar incluso el punto de saturación, añadiéndose arcillas para mantener en suspensión las partículas que no se disuelven, pero las suspensiones resultantes tienen el inconveniente de que necesitan una fuerte agitación, requiriendo materiales y equipos especiales, y su utilización solo se aplica en cultivos extensivos.Liquid fertilizers are solutions of fertilizing salts, of various compositions and with levels of dissolution near saturation point in water. It can even exceed the saturation point, adding clays to keep suspended particles that do not dissolve, but the resulting suspensions have the disadvantage that they need strong agitation, requiring special materials and equipment, and its use only applies to extensive crops.
Existen también fertilizantes en forma de gel, formados utilizando arcillas, por ejemplo según el procedimiento de la Patente de Invención Española 200500473 que pertenece a la misma solicitante de la presente invención.There are also fertilizers in gel form, formed using clays, for example according to the procedure of the Spanish Invention Patent 200500473 which belongs to it Applicant of the present invention.
Dichos fertilizante en forma de gel, también tienen sin embargo los inconvenientes siguientes:Such gel-shaped fertilizer, too however, they have the following disadvantages:
- --
- Solo son viables para pequeñas cantidades envasadas y, aún así, tienen poca estabilidad, porque en poco tiempo se produce su decantación.Alone they are viable for small quantities packaged and still have little stability, because in a short time its decanting
- --
- Al llevar arcillas en la composición, obturan los filtros que se utilizan en las instalaciones de fertirrigación, así como las tuberías y los goteros de dichas instalaciones.To the carry clays in the composition, seal the filters that used in fertigation facilities, as well as pipes and drippers of these facilities.

Dichos fertilizante en forma de gel no pueden por tanto comercializarse en grandes cantidades, ni almacenarse, admitiendo solo pequeños envasados y esto incluso con limitaciones.Such gel-shaped fertilizer cannot therefore be sold in large quantities, or stored, admitting only small packages and this even with limitations
De acuerdo con la invención se propone un producto fertilizante de naturaleza liquida pero susceptible de una alta concentración sin incorporar arcillas, y con una estabilidad que hace que prácticamente no se produzcan decantaciones ni precipitados, permitiendo por lo tanto el almacenaje en condiciones normales.According to the invention, a fertilizer product of a liquid nature but susceptible to high concentration without incorporating clays, and with stability which means that there are practically no decants or precipitates, thus allowing storage under conditions normal.
Este producto objeto de la invención se forma por una solución de Nitrato Potásico con una adición de Exopolisacárido, en agua, según unas proporciones en peso de entre 20 y 60% de Nitrato Potásico sólido, entre 0,2 y 0,7% de Exopolisacárido y el resto de agua hasta el 100% en cada caso.This product object of the invention is formed for a solution of potassium nitrate with an addition of Exopolysaccharide, in water, according to proportions by weight between 20 and 60% solid potassium nitrate, between 0.2 and 0.7% of Exopolysaccharide and the rest of water up to 100% in each case.
Una combinación particular de formación de este producto, con buenos resultados de concentración y estabilidad, es, por ejemplo, con 50% de Nitrato Potásico sólido, 0,5% de Exopolisacárido y 49,5% de agua.A particular combination of formation of this product, with good concentration and stability results, is, for example, with 50% solid potassium nitrate, 0.5% of Exopolysaccharide and 49.5% water.
Se obtiene así un producto que es utilizable para fertirrigación y para fabricar soluciones nutritivas madre, destacando por las ventajas siguientes:A product that is usable is thus obtained for fertirrigation and to manufacture nutritious solutions mother, Noting for the following advantages:
- --
- Es un producto con partículas que no están disueltas ni son mantenidas en suspensión por arcillas, sino que se trata de una suspensión sobresaturada que tiene partículas sólidas, ofreciendo las ventajas de un líquido en cuanto a su manipulación más cómoda que la de un sólido y, además con una concentración muy cercana a la de un sólido; siendo sus partículas sólidas muy solubles, de manera que cuando se inyectan en la red de riego se disuelven totalmente.Is a product with particles that are not dissolved or maintained in clays suspension, but it is a suspension supersaturated that has solid particles, offering the advantages of a liquid in terms of handling more comfortable than that of a solid and also with a concentration very close to that of a solid; its solid particles being very soluble, so that when they are injected into the irrigation network they dissolve totally.
- --
- Tiene una estabilidad constante a lo largo del tiempo, y no necesita agitación, pudiendo manejarse en grandes volúmenes a granel.Have constant stability over time, and does not need agitation, being able to handle large volumes at bulk.
- --
- Al no tener arcillas, no provoca obturación de los filtros que se disponen en las salidas de los tanques de almacenamiento, ni en las tuberías y goteros de las instalaciones de riego por goteo.By not have clays, does not cause clogging of the filters that are arranged at the exits of the storage tanks, nor in the pipes and drippers from drip irrigation facilities.
- --
- Se puede almacenar sin necedad de agitación, permitiendo por lo tanto una utilización cómoda de aplicación, ya que permite salvar situaciones climatológicas adversas o averías de las maquinarias de aplicación, puesto que la posibilidad de almacenamiento durante días, posibilita mantenerle en espera durante el tiempo que no se puede realizar la aplicación.Be can store without stubbornness of agitation, thus allowing a comfortable use of application, since it allows to save adverse weather conditions or breakdowns of the machinery of application, since the possibility of storage during days, it allows you to keep it on hold for as long as You can make the application.
- --
- Contribuye a disminuir la cantidad de CO_{2} que se emite a la atmósfera y reduce el coste del transporte, ya que al tener una concentración alta se pueden transportar más unidades fertilizantes en un menor volumen de producto transportado.It helps to reduce the amount of CO2 that is emitted into the atmosphere and reduces the cost of transport, since having a high concentration can transport more fertilizer units in a smaller volume of product transported.
