Description
Moyens pour l'amélioration de la nutrition des plantesMeans for improving plant nutrition
La présente invention est relative à des moyens, à savoir un procédé et des préparations, pour l'amélioration de la nutrition des plantes. The present invention relates to means, namely a method and preparations, for improving the nutrition of plants.
Les modes de production agricoles évoluent. Aujourd'hui, l'ensemble de la filière agricole recherche des solutions pour raisonner l'apport d'engrais en fonction des besoins de la plante. Agricultural production patterns are changing. Today, the whole agricultural sector is looking for solutions to reason the supply of fertilizers according to the needs of the plant.
Dans ce contexte, les nouvelles méthodes de culture et les produits visent à mieux valoriser les nutriments déjà présents dans les sols ou ceux qui y sont apportés par la fertilisation, notamment en favorisant l'activité microbienne et biologique des sols. Diverses solutions sont proposées, qui visent à amener des micro-organismes ou des produits qui augmentent l'activité des micro-organismes du sol. Ces produits sont > soit des engrais minéraux ou organiques (composts, fumiers, produits industriels) qui permettent, dans une faible mesure, de dynamiser la vie microbienne du sol. Mais cette utilisation n'est pas leur vocation principale qui reste la nutrition de la plante. Ainsi, ils sont avant tout des supports nutritionnels pour la plante et dans une certaine mesure pour les micro-organismes. In this context, new cultivation methods and products aim to improve the value of nutrients already present in soils or those provided by fertilization, particularly by promoting microbial and biological soil activity. Various solutions are proposed that aim to bring microorganisms or products that increase the activity of soil microorganisms. These products are> or mineral or organic fertilizers (composts, manure, industrial products) which allow, to a small extent, to boost the microbial life of the soil. But this use is not their main purpose which remains the nutrition of the plant. Thus, they are above all nutritional supports for the plant and to a certain extent for microorganisms.
> soit des bactéries, comme les Bad/lus, qui sont employées comme probiotiques du sol. Leur rôle est de modifier le milieu de manière à aider le développement d'une certaine microflore qui serait favorable à la nutrition de la plante. Les travaux de l'inventeur ont montré qu'en utilisant certains micro-organismes, il était possible de dynamiser la nutrition de la plante ou la flore du sol et/ou d'augmenter l'activité microbienne des sols ou la nutrition de la plante. > or bacteria, such as Bad / lus, which are used as soil probiotics. Their role is to modify the environment so as to help the development of a certain microflora that would be favorable to the nutrition of the plant. The work of the inventor has shown that by using certain microorganisms, it is possible to boost the nutrition of the plant or the soil flora and / or to increase the microbial activity of the soil or the nutrition of the plant. .
L'invention a donc pour but de fournir un procédé pour l'amélioration des plantes comportant l'application au sol de micro-organismes de grande efficacité, pour augmenter l'activité métabolique des micro-organismes du sol et améliorer la nutrition des plantes. The object of the invention is therefore to provide a process for the improvement of plants comprising the application of high efficiency micro-organisms to the soil, to increase the metabolic activity of the soil micro-organisms and to improve the nutrition of the plants.
Elle vise également l'application de ces micro-organismes comme fertilisants et de nouvelles préparations les renfermant. It is also aimed at the application of these micro-organisms as fertilizers and new preparations containing them.
Le procédé selon l'invention est caractérisé par l'utilisation, comme micro-organismes, d'une préparation de levures actives et/ou inactives, et/ou de fractions de levures, telles que des extraits de levures. The process according to the invention is characterized by the use, as microorganisms, of a preparation of active and / or inactive yeasts, and / or yeast fractions, such as yeast extracts.
L'application de telles préparations au sol, sous forme de solutions ou de suspensions aqueuses, améliore la nutrition de la plante et permet aussi, de façon surprenante et inattendue, une meilleure assimilation des éléments minéraux qui sont présents dans le sols, même s'ils sont réputés assimilables. The application of such preparations to the soil, in the form of solutions or aqueous suspensions, improves the nutrition of the plant and also allows, surprisingly and unexpectedly, a better assimilation of the mineral elements that are present in the soil, even if they are deemed assimilable.
Les levures inactives de ces préparations sont, notamment, soit des levures thermiquement inactivées, soit des levures partiellement hydrolysées, ou des fractions de levures. The inactive yeasts of these preparations are, in particular, either thermally inactivated yeasts, partially hydrolysed yeasts, or yeast fractions.
Les préparations mises en oeuvre comprennent des levures d'un seul genre ou des mélanges de plusieurs genres. The preparations used include yeasts of one kind or mixtures of several kinds.
Le procédé de l'invention est encore caractérisé en ce que les préparations de levures actives et/ou inactives et/ou les fractions de levures sont sous forme de suspensions ou de solutions, ou sous forme sèche, par exemple de poudres, granulés ou paillettes. The process of the invention is further characterized in that the active and / or inactive yeast preparations and / or the yeast fractions are in the form of suspensions or solutions, or in dry form, for example powders, granules or flakes. .
Des levures particulièrement appropriées sont produites, de façon non limitative, à partir de souches du genre Saccharomyces, Candida, Torula. Particularly suitable yeasts are produced, without limitation, from strains of the genus Saccharomyces, Candida, Torula.
De manière avantageuse, le procédé d'amélioration de la nutrition des plantes selon l'invention comprend l'application au sol desdites levures actives et/ou inactives et/ou des fractions de levures, telles que des extraits de levures, à des doses de 0,1 à 100 Kg de matière sèche par hectare et par application. Advantageously, the process for improving the nutrition of the plants according to the invention comprises the application to the soil of said active and / or inactive yeasts and / or yeast fractions, such as yeast extracts, at doses of 0.1 to 100 kg of dry matter per hectare and per application.
Selon une variante de réalisation, le procédé de l'invention est mis en oeuvre avec un traitement classique d'application d'engrais minéraux et/ou organiques et/ou d'oligo-éléments. According to an alternative embodiment, the process of the invention is carried out with a conventional treatment for the application of mineral and / or organic fertilizers and / or trace elements.
En apportant dans le sol, en plus de la fertilisation minérale et/ou organique, des levures telles que définies ci-dessus, qui favorisent l'assimilation des composés minéraux et organiques, même s'ils sont réputés assimilables directement par la plante, on améliore l'efficacité des engrais, tels que nitrates, phosphates, ou potasse. By bringing into the soil, in addition to the mineral and / or organic fertilization, yeasts as defined above, which promote the assimilation of mineral and organic compounds, even if they are deemed to be directly assimilable by the plant, improves the efficiency of fertilizers, such as nitrates, phosphates, or potash.
Les levures actives ou inactives peuvent être alors introduites dans les engrais minéraux et/ou organiques avec lesquels elles ont un effet synergique suite à leur épandage sur ou dans le sol. Active or inactive yeasts can then be introduced into the mineral and / or organic fertilizers with which they have a synergistic effect following their spread on or in the soil.
L'invention vise donc, également, l'utilisation des levures actives et/ou inactives telles que définies ci-dessus en tant fertilisants, ainsi que de des préparations renfermant ces levures en mélange avec des engrais minéraux et/ou organiques, et/ou des préparations d'oligo-éléments, destinées à améliorer la nutrition des plantes. The invention therefore also relates to the use of active yeasts and / or inactive as defined above as fertilizers, as well as preparations containing these yeasts mixed with inorganic and / or organic fertilizers, and / or micronutrient preparations for improving plant nutrition.
D'autres caractéristiques et avantages de l'invention sont donnés dans les exemples qui suivent qui illustrent, de façon non limitative, les résultats obtenus sur la production de biomasses du Ray Grass, lors de l'application au sol de levures inactives (exemple 1) et sur production de fruits et de biomasse de plants de tomates, après apport de levures actives au sol. Other characteristics and advantages of the invention are given in the following examples which illustrate, in a nonlimiting manner, the results obtained on the production of Ray Grass biomasses, during the inactive soil application of inactive yeasts (example 1). ) and fruit and biomass production of tomato plants, after active yeasts have been added to the soil.
