Abstract

A fortifying compound with a high calcium content is described for its application to plants and crops, especially fruits, to activate the self-defense of the plant by increasing the capacity of calcium absorption by plant tissues. The compound consists of a combination of components such as calcium nitrate, calcium lignosulfonate, polyhydroxycarboxylic acids, an elicitor component and water. The compound takes the form of a liquid preparation, is soluble in water and is applied by fertigation through localized irrigation. (Machine-translation by Google Translate, not legally binding)

A fortifying compound for plants.

Object of the invention

The present invention relates to a compound fortifying for plants, which provides essential characteristics of novelty and notable advantages over known media and used for the same purposes in the current state of the technique.

More particularly, the invention proposes the development of a fortifying substance for plants (or phyto-fortifier), intended to increase the plant's self-defense to which it is applied thanks to the increase in calcium absorption that causes in the plant, consisting of a liquid preparation with a high calcium content complexed by lignosulfonates and acids polyhydroxycarboxylates, and enhanced by a fortifying elicitor. The liquid formulation is water soluble and can be used through fertirrigation in localized irrigation, during the whole phase of vegetative development of the crop.

The scope of the invention is is obviously included within the industrial sector dedicated to the manufacture of fertilizers, fertilizers and biostimulants in general.

Background and Summary of the Invention

Those skilled in the art are knowledgeable about the effects that calcium, as a secondary nutrient, has on the plants. Each plant needs calcium to grow and once fixed, calcium is not mobile in the plant, but is a important constituent of cell walls or can only be supplied by the sap of the xylem. When he runs out calcium supply in the plant, it cannot remobilize the Calcium from older tissues. So, when a calcium deficiency in a plant, the immediate consequences they are, among others, necrosis in the tips and in the margins of the young leaves, bulb and fruit abnormalities, deformation of the affected leaves, highly branched root systems, growth severely impeded, and general chlorosis.

As will be understood, calcium constitutes a element that allows plants to trigger a series of self-defense mechanisms, which help overcome many problems related to the environmental changes of the place where The plant develops and grows.

On the other hand, subject matter experts are also aware of the action on plants of a substance known as elicitor. The action of this substance on the nature of plants is very important because, apart from act as a powerful rooting, induces the formation of Natural self-defense known as phytoalexins. Phytoalexins they are substances that are produced by the plant naturally, they constitute natural defense mechanisms that allow the plant fight infections, especially those caused by bacteria and mushrooms. Phytoalexins are not normally stored in the plant, but when they are attacked by bacteria or fungi, they begin to produce very quickly due to the action of internal elicitors (or endoelicitors), forming around the areas where It causes the infection.

Based on the indications set forth in the foregoing in regard to the need for calcium to the plants and regarding the behavior of natural products generated by the plants themselves for self-defense purposes, the This invention has been proposed as the main objective of creation of a phyto-fortifying product that can be applied directly to plants and crops, and to contribute to plants the necessary components for the commented functions. This objective has been fully achieved through the compound fortifying that will be described in what follows, and whose main characteristics are collected in the portion characterizing claim 1 attached.

Description of a preferred embodiment

According to the above, the object of the invention consists in the formulation of a fortifying compound that is capable of greatly increasing the ability to calcium absorption by the plants to which it is applied, with the result of increasing their self-defense.

In a preferred embodiment, the compound consists of a concentrated liquid preparation, soluble in water, with a high calcium content, complexed by lignosulfonates and polyhydroxycarboxylic acids, together with a elicitor component. The preferred compound responds to the formula Qualitative and quantitative following:

The above percentages must be understood in weigh. The elicitor component used in the tests performed has been one commercially available under the brand ACT-2 ™ manufactured by Menadiona, S.A. Also, how to carry out the combination of the various components that integrate the compound and the conditions of embodiment, are in accordance with known methods and used in the Current state of the art.

Since, as stated, the compound of The above formula is water soluble, its preferred application is performed by fertirrigation, in irrigation located throughout the phase of vegetative development of the crop.

The compound of the invention has proven to be highly effective in activating the self-defense of the plant due to the increase in calcium absorption by the plant tissues, since calcium constitutes a factor of quality in plants, especially in fruits and an important activator of certain basic biological processes. This makes its use significantly reduces damage to crops certain physiopathies related to this element (tip-burn, fruit softening, rot apical, cracking, bitter-pit, etc.).

It is not considered necessary to make the content of the present description so that an expert in the matter can understand its scope and the advantages of it are derived, as well as carrying out the practical realization of their object.

Notwithstanding the foregoing, and since the description given corresponds only to an example of preferred embodiment, it will be understood that within its essentiality may introduce modifications and variations of detail, also within the scope of the invention, which in particular may affect characteristics such as the nature of the components involved in the composition of the product, the variable amounts in which they can participate, the forms and the methods of making the combinations, or any other that do not involve alteration of the basis of the defined invention by the claims that follow.
