Antecedentes de la invenciónBackground of the invention

En la patente principal P200500173, se reivindica un compuesto de agua, celulosa y nutrientes en forma gelatinosa de lenta liberación que se convierten gradualmente en líquido al entrar en contacto con la actividad microbiológica natural del suelo, lo que supone un nuevo concepto en el riego de las plantas: un producto 100% natural que permite mantener las plantas en perfecto estado durante 30 días o más (según las dosis aportadas) sin necesidad de regarlas ni abonarlas. El agua, los nutrientes y la propia celulosa que libera de forma gradual y constante es cien por cien utilizable por las raíces de la planta, el agua disolviendo los nutrientes propios de la tierra del tiesto, y la celulosa junto con el nitrato potásico actuando como nutrientes complementarios y de refuerzo.In the main patent P200500173, claims a compound of water, cellulose and nutrients in form slow-release gelatinous that gradually become liquid when in contact with microbiological activity natural soil, which is a new concept in the irrigation of the plants: a 100% natural product that allows to maintain the plants in perfect condition for 30 days or more (depending on the dose provided) without the need to water or fertilize them. The water, the nutrients and cellulose itself that gradually releases and constant is one hundred percent usable by the roots of the plant, water dissolving the earth's own nutrients from the pot, and cellulose together with potassium nitrate acting as nutrients  Complementary and reinforcement.

Concretamente, el novedoso compuesto para la nutrición y el riego de plantas está formado por tres elementos, agua en un 94 a un 96,2% en peso, celulosa en un 3,5 a un 4% en peso y nitrato potásico en un 0,4 a un 3,5% en peso.Specifically, the novel compound for Nutrition and plant irrigation is made up of three elements, water in 94 to 96.2% by weight, cellulose in 3.5 to 4% in weight and potassium nitrate 0.4 to 3.5% by weight.

En esta composición, las moléculas de agua y nitrato potásico quedan mecánicamente enlazadas con la molécula de celulosaIn this composition, the water molecules and potassium nitrate are mechanically linked to the molecule of cellulose

Este compuesto a temperatura ambiente presenta una consistencia gelatinosa, siendo envasado para su uso en un contenedor de material plástico dotado de una tapa superior.This compound at room temperature presents a gelatinous consistency, being packaged for use in a plastic container with an upper lid.

Descripción detallada de la invenciónDetailed description of the invention

Concretamente, las mejoras introducidas en el objeto de la patente principal P200500173 consisten el la sustitución total o parcial de nitrato potásico presente en un porcentaje en peso de entre un 0,4 a un 3,5% en el compuesto reivindicado en la patente principal, por un elemento diferente capaz de enlazarse mecánicamente con la molécula de celulosa para ser liberado sistemáticamente conforme la actividad microbiológica destruye los enlaces químicos. Estos elementos se organizan en cuatro grupos según su función:Specifically, the improvements introduced in the object of the main patent P200500173 consist of the total or partial replacement of potassium nitrate present in a weight percentage between 0.4 to 3.5% in the compound claimed in the main patent, by a different element capable of mechanically binding with the cellulose molecule to be systematically released according to microbiological activity Destroy chemical bonds. These elements are organized in Four groups according to their function:

- Grupo de abonos foliares y radiculares, formado por diferentes mezclas de Nitrógeno, óxido de Fósforo, óxido de Potasio, óxido de Magnesio, Boro, Zinc, Magnesio, Molibdeno, Hierro, más micronutrientes quelatados en una proporción en todos los casos no superior al 0,5%. Estos ingredientes pueden haber sido quelatados por EDTA, DTPA, EDDHA, Boro y ácido heptaglucónico. También pueden ser aportados por diferentes tipos de arcillas ricas en todos o parte de los minerales descritos. Estos abonos tienen como función el aporte natural de minerales a las plantas, son aplicables por vía foliar, radicular o fertirrigación.- Group of foliar and root fertilizers, formed by different mixtures of nitrogen, phosphorus oxide, Potassium oxide, Magnesium oxide, Boron, Zinc, Magnesium, Molybdenum, Iron, plus chelated micronutrients in a proportion in all cases not exceeding 0.5%. These ingredients can have been chelated by EDTA, DTPA, EDDHA, Boron and acid Heptagluconic They can also be provided by different types of clays rich in all or part of the minerals described. These fertilizers have as their function the natural contribution of minerals to plants, are applicable by foliar, root or fertigation

- Grupo de correctores de salinidad, formado por óxido de Calcio complejado por lignosulfonatos y ácido heptaglucónico en un porcentaje en peso entre un 0,4% a un 3,5% del total. Este corrector de salinidad tiene como función suplir la carencia de calcio.- Group of salinity correctors, formed by Calcium oxide complexed by lignosulfonates and acid heptagluconic in a percentage by weight between 0.4% to 3.5% of total. This salinity corrector has the function of supplying the lack of calcium

- Grupo de bioestimulantes, formado por fosfitos de potasa equivalentes a 60% de ácido fosforoso, o una mezcla de nitrógeno proteico más aminoácidos libres más oligopéptidos más polipéptidos procedentes de hidrólisis controlada sin cloruros. Estos elementos se incorporan al compuesto en una proporción entre un 0,4% a un 3,5% en peso y tienen una función estimulante de las defensas naturales de las plantas contra hongos. Sistemático por vía foliar, radicular y absorbido incluso por la corteza.- Group of biostimulants, formed by phosphites of potash equivalent to 60% phosphorous acid, or a mixture of protein nitrogen more free amino acids more oligopeptides more polypeptides from controlled hydrolysis without chlorides. These elements are incorporated into the compound in a proportion between 0.4% to 3.5% by weight and have a stimulating function of natural defenses of plants against fungi. Systematic by foliar path, root and absorbed even by the bark.

- Grupo de ácidos húmicos y fúlvicos (HUMUS), constituidos por moléculas orgánicas complejas que se forman por la degradación de la materia orgánica a través de la acción de microorganismos del suelo y las lombrices de tierra. Preferiblemente, la procedencia de este humus será la leonardita de los yacimientos de Montana y Dakota (usa) siendo sometido previamente a un tratamiento de sulfonación para modificar sus propiedades físico químicas para usar por vía foliar, radicular o fertirrigación. La incorporación de estos ácidos húmicos y fúlvicos al compuesto general en una proporción de entre un 0,4% a un 3,5% en peso.- Group of humic and fulvic acids (HUMUS), constituted by complex organic molecules that are formed by the degradation of organic matter through the action of soil microorganisms and earthworms. Preferably, the origin of this humus will be the leonardite of the deposits of Montana and Dakota (usa) being submitted prior to a sulfonation treatment to modify its Physical chemical properties to use by foliar, root or fertigation The incorporation of these humic and fulvic acids to the general compound in a proportion between 0.4% to 3.5% in weigh.

De esta forma se consigue un compuesto final formado por agua en un 94% a un 96,2% en peso, celulosa en un 3,5% a un 4% en peso, y un compuesto complementario en una proporción de entre un 0,4% a un 3,5% en peso de la composición, el cual a su vez esta constituido por un 0% a un 95% de nitrato potásico y un 5% a un 100% de cualquiera de los elementos descritos en los cuatro grupos citados anteriormente o de una combinación de dos o más de estos.In this way a final compound is achieved formed by water 94% to 96.2% by weight, cellulose 3.5% at 4% by weight, and a complementary compound in a proportion of between 0.4% to 3.5% by weight of the composition, which in turn it is constituted by 0% to 95% potassium nitrate and 5% to 100% of any of the elements described in the four groups cited above or a combination of two or more of these.
