Description

Producto desbloqueante de nutrientes para fertirrigación.Nutrient Unlocking Product for fertirrigation

Technical sector

La presente invención está relacionada con el acondicionamiento del riego para facilitar la nutrición de las plantas, proponiendo un producto que, añadido al agua de riego, permite bajar de manera considerable el pH del suelo, facilitando que las plantas puedan tomar los nutrientes existentes en la tierra.The present invention is related to the irrigation conditioning to facilitate the nutrition of plants, proposing a product that, added to the irrigation water, allows to lower the pH of the soil considerably, facilitating that plants can take the nutrients in the land.

State of the art

En algunas zonas geográficas los suelos presentan mayoritariamente un fuerte contenido en Caliza (Carbonato Cálcico), circunstancia ésta que hace complicada la nutrición vegetal, ya que son suelos básicos, en los que se producen bloqueos importantes del Fósforo, Cinc, Manganeso y Hierro, fundamentalmente, lo cual supone una inmovilización de los nutrientes que hace que no resulten disponibles para las plantas.In some geographical areas the soils they present mostly a strong content in Limestone (Carbonate Calcic), a circumstance that makes nutrition complicated vegetable, since they are basic soils, in which blockages occur important phosphorus, zinc, manganese and iron, fundamentally, which supposes an immobilization of nutrients that does not are available to plants.

Este problema se puede minimizar mediante riegos por goteo que permitan bajar el pH del suelo en la zona denominada bulbo radicular, que es donde se concentran las raíces de las plantas, ya que con ello se desbloquean los elementos nutritivos insolubles que contiene la tierra, convirtiéndolos en solubles, de forma que pueden ser asimilados por las plantas.This problem can be minimized by irrigation drip that allow lowering the pH of the soil in the area called root bulb, which is where the roots of the plants, as this unlocks the nutritional elements insoluble that the earth contains, making them soluble, of form that can be assimilated by plants.

El pH óptimo para que las plantas puedan tomar los nutrientes de la tierra se halla entre el 6,2 y el 6,8, mientras que lo habitual en los suelos calizos es que el pH esté normalmente por encima de 8.The optimal pH for plants to take the nutrients of the earth is between 6.2 and 6.8, while What is usual in limestone soils is that the pH is normally above 8.

Con los productos líquidos ácidos que se vienen utilizando para ese fin, no se consigue acidificar suficientemente esos suelos calizos, ya que:With the acidic liquid products that come using for that purpose, it is not possible to acidify sufficiently those limestone soils, since:

--: pH del suelo = 8pH of soil = 8

--: pH del agua de riego = 7,5pH of irrigation water = 7.5

--: pH de un fertilizante líquido convencional = 2pH of a conventional liquid fertilizer = 2

--: pH de la mezcla agua-fertilizante = 7,3.pH of the water-fertilizer mixture = 7.3.

       \vskip1.000000\baselineskip\ vskip1.000000 \ baselineskip

Con lo cual no se consigue una aproximación adecuada al pH óptimo de 6,5, para que las plantas puedan tomar los nutrientes.With which an approximation is not achieved adequate to the optimum pH of 6.5, so that the plants can take the nutrients.

Por otro lado, los fertilizantes líquidos convencionales tienen un alto poder corrosivo de todos los materiales metálicos, incluido el acero inoxidable, lo cual condiciona de un modo importante el envasado de los mismos.On the other hand, liquid fertilizers Conventionals have a high corrosive power of all metallic materials, including stainless steel, which It conditions in an important way their packaging.

Object of the invention

De acuerdo con la invención se propone un producto destinado para ser añadido al agua del riego por goteo, con el cual se consigue bajar el pH hasta un valor que permite desbloquear de una manera ventajosa los nutrientes bloqueados en el suelo, para que puedan ser asimilados por las plantas.According to the invention, a product intended to be added to drip irrigation water, with which is able to lower the pH to a value that allows unblocking in an advantageous way the nutrients blocked in the soil, so that they can be assimilated by plants.

Este producto objeto de la invención se forma por una solución de Ácido Nítrico, Nitrato Potásico, Ácido Fosfórico y Nitrato Amónico, en agua, con unas proporciones en peso de entre 0,5 y 50% de Ácido Nítrico, entre 6 y 20% de Nitrato Potásico, entre 2 y 35% de Ácido Fosfórico, entre 2 y 40% de Nitrato Amónico y el resto agua hasta el 100% en cada caso.This product object of the invention is formed by a solution of Nitric Acid, Potassium Nitrate, Phosphoric Acid and Ammonium Nitrate, in water, with proportions by weight of between 0.5 and 50% Nitric Acid, between 6 and 20% Potassium Nitrate, between 2 and 35% Phosphoric Acid, between 2 and 40% Ammonium Nitrate and the water remains up to 100% in each case.

Una combinación concreta de formación del producto, en porcentajes de peso, con buen resultado para la finalidad desbloqueante de los nutrientes en suelos de pH alto, es, por ejemplo, con 10,2% de Ácido Nítrico, 6,5% de Nitrato Potásico, 5,8% de Ácido Fosfórico, 37,6% de Nitrato Amónico y 39,9% de agua.A concrete combination of product, in weight percentages, with good results for unblocking purpose of nutrients in high pH soils, is, for example, with 10.2% Nitric Acid, 6.5% Potassium Nitrate, 5.8% Phosphoric Acid, 37.6% Ammonium Nitrate and 39.9% Water.

Otro ejemplo de combinación de la formación del producto, en porcentajes de peso, también con buenos resultados para la finalidad de desbloquear los nutrientes de la tierra, es con 7,7% de Ácido Nítrico, 15,2% de Nitrato Potásico, 19,2% Ácido Fosfórico, 2% de Nitrato Amónico y 55,9% de agua.Another example of combining the formation of product, in weight percentages, also with good results for The purpose of unlocking nutrients from the earth is with 7.7% Nitric Acid, 15.2% Potassium Nitrate, 19.2% Phosphoric Acid, 2% Ammonium Nitrate and 55.9% water.

Se obtiene de este modo un producto muy ácido, con el cual se consigue una reducción drástica del pH del agua utilizada en el riego por goteo, permitiendo una acción muy efectiva del desbloqueo de los nutrientes de la tierra, de manera que con la aplicación en el riego de las plantaciones sobre suelos calizos, se mejora sensiblemente la nutrición de las plantas y por consiguiente la productividad de las mismas.In this way a very acidic product is obtained, with which a drastic reduction of the pH of the water is achieved used in drip irrigation, allowing a very effective action of unlocking the nutrients from the earth, so that with the application in the irrigation of plantations on limestone soils, significantly improves plant nutrition and therefore their productivity.

La composición del producto, a pesar de ser muy ácida, no es corrosiva del acero inoxidable ni de los plásticos, lo cual supone a su vez una ventaja para el envasado con garantías en envases económicos, resistentes y duraderos.The composition of the product, despite being very acid, it is not corrosive of stainless steel or plastics, what which in turn is an advantage for packaging with guarantees in Economical, resistant and durable containers.
