PRODUIT D'EPANDAGE POUR
L'AMENDEMENT DES SOLS ET
PROCEDE POUR SA PREPARATION
L'invention a pour objet un produit d'epandage pour l'amendement des sols, notamment pour l'ame- lioration des sols des terres agricoles cultivables, de serres et/ou de plantes en pot.
Pour obtenir une amelioration de la structu-
EMI1.1
re des sols de ce type, il est propose plusieurs sysI tèmes, entre autres de la tourbe d'engrais qui est un engrais utilise sous des formes variées. 11 s'agissait autrefois avant tout de la tourbe blanche brunâtre que l'on trouve surtout en Europe Centrale et qui est de plus en plus remplacée par la tourbe noire. La tourbe est constituee pour 40 A 50 % en poids de substances organiques et d'eau ainsi que de 1 A 2 % en poids de minéraux (cendres).
Du fait de l'utilisation intensive et des hauts rendementsdes sols et donc de la dette- rioration de leur structure, d'une part on constate une demande croissante notamment de substrats humiques de tourbe, et d'autre'part que la poursuite de l'exploitation de gisements naturels de tourbe n'est plus rentable A long terme.
On utilise aussi des granulats de styropor pour ameliorer la structure des sols, notamment pour les ameublir. Les granulats de polystyrene expansible tel celui denommé "Styropor"n'assurent cependant qu'un ameublissement du sol et ne permettent pas un apport simultané de substances nutritives.
<Desc/Clms Page number 2>
La présente invention se propose donc de re- aliser un produit d'épandage du type précite qui permette de renoncer A utiliser de la tourbe et A l'aide duquel il soit possible d'améliorer les propriétés physiques et chimiques des sols, et de favoriser la croissance des plantes s'enracinant dans ces sols.
L'invention a reconnu que l'on dispose de différentes substances poreuses naturelles présentant une porosité ouverte importante et qui contiennent des additifs appropries, et qui par conséquent peuvent servir de substances de support pour introduire dans le sol des elements nutritifs essentiels.
L'invention propose de même un produit d'e- pandage constitué d'une substance de support granulai- : re, présentant une porosité importante, en association : avec de l'acide humique et/ou ses sels', la substance granulaire de support etant de préférence enrobée d'acide humique et/ou de ses sels.
GrAce cl l'incorporation d'acide humique ou de ses sels dans une substance poreuse de support qui est repandue sur le sol ou incorporée'3 celui-ci, on peut obtenir une répartition uniforme de l'acide humique dans le sol. Du fait de la porosité ouverte extrêmement grande de la pierre volcanique expansée utilisée de préférence comme substance support, en particulier la perlite, l'acide humique est incorpore à la substance de support pendant un certain temps, ce qui fait qu'elle peut être cédée en continu et lentement, au sol environnant.
De préférence, la substance de support poreuse, granulaire est imprégnée d'acide humique ou de ses sels, jusqu' ce que l'on obtienne le degré d'enrobage souhaité, puis elle est séchée. L'acide humique est généralement obtenu A partir de ltgnite et constitue une matière premiere relativement bon marche que
<Desc/Clms Page number 3>
l'on peut se procurer dans le commerce. Ce produit d'épandage est particulièrement avantageux pour les sols A structure spécialement faible. L'acide humique ou ses sels tels que les sels de potassium ou de sodium servent de substances de croissance et de produits d'amendement pour les sols à structure faible ou pauvres en échanges.
L'acide humique favorise l'activité des organismes vivants du sol, y compris des vers de terre ; il ne contient aucun additif artificiel, il améliore la structure du sol, directement par l'ameublissement des sols lourds et indirectement en favorisant la production de colles bactériennes, permettant aux fines particules de s'assembler en grumeaux. De cette façon, on obtient surtout un ameu-
EMI3.1
blissement du sol. En outre, l'acide humique accrolt la capacité de rétention de l'eau du sol. Ceci est le résultat d'une part, de la fixation'de l'eau dans la substance organiques, d'autre part de l'amélioration de la structure du sol.
En outre, des substances de l'humus-acide humique-améliorent l'aeration du sol, puisqu'une bonne structure grumeleuse produit des pores plus importants, d'oh un meilleur apport d'oxygène aux racines et un échappement sans probleme du dioxyde de carbone de la zone des racines. D'autre part, l'acide humique ou ses sels sont en mesure d'accumuler les substances nutritives à leur surface sous une forme favorisant les échanges, ce qui est particulièrement important pour les sols faiblement argileux. En outre, du fait de leur pouvoir de retention d'eau, l'acide humique et ses sels, font que les sols peuvent supporter sans dégradations des périodes de sécheresse.
L'association de l'acide humique et de la perlite presente cet avantage particulier que cette roche volvanique expansée est une matière inorganique, très légère, de surface relativement importante, ce
<Desc/Clms Page number 4>
qui fait que l'application permet de répartir la préparation humique de manière optimale dans le sol. On utilise des grains de perlite dont la grosseur est comprise entre 2 et 10 mm, et de preference entre 2 et 5 mm.
Afin de garantir que les constituants humiques seront cédés lentement au sol après épandage ou incorporation, le produit d'épandage peut contenir un liant. Ce liant peut être un verre soluble (silicate de potassium et/ou silicate de sodium). Un silicate de potassium est particulièrement avantageux puisqu'il offre en outre du potassium qui est un ion nutritif.
Pour que le produit d'épandage reste"cou- liant", lors du processus de fabrication on ajoute de l'acide silicique après imprégnation de la perlite par la solution constituée de verre soluble et d'acide humique (ou de ses sels), alors que le produit d'épandage est encore à l'état humide. La liaison chimique de l'eau a pour effet d'assécher le produit qui n'a pas besoin d'être spécialement seche. En outre, le verre soluble ou l'acide silicique a des effets positifs sur la résistance de toute une série de plantes de culture et de plantes décoratives. En particulier pour les céréales, l'acide silicique consolide le tissu de soutien, ce qui a pour effet de renforcer la stabilité des tiges et de réduire la verse.
En outre, l'acide silicique favorise la résistance aux maladies fongiques. Bien souvent, le silicate inhérent au sol n'est pas mobilisable dans une mesure suffisante. Or, le produit d'epandage suivant l'invention a encore pour avantage d'apporter un silicate soluble et facilement mobilisable.
D'autre part, le produit d'épandage peut aussi contenir une proportion de substances revitali-
<Desc/Clms Page number 5>
santes, en particulier de la dolomite, des phosphates, diverses substances de croissance, de l'acide silicique precipite et/ou du carbonate de magnesium.
L'emploi de magnésium est le plus souvent nécessaire car la carence en magnesium se fait particulièrement sentir dans les plantes engraissées de manière intensive avec des engrais contenant de l'azote, des phosphates et du potassium. Tel est souvent
EMI5.1
le cas en particulier pour les plantes decoratives. Ceci est particulierement vrai au fur et à mesure que les plantes perdent du magnesium par suite de leur croissance et en raison des pertes par lixiviation, en particulier sur les sols acides.
Pour prévenir un manque d'oligo-éléments, la composition peut aussi contenir un mélange d'oligo- ! elements complexes. De préférence, ces éléments sont liés de marnière complexe A l'EDTA (acide thylenedia- mine-tetracetique) sous une forme pouvant etre facilement assimilde par les plantes. On peut utiliser à cet effet les oligo-éléments suivants : cuivre, fer, manganese, magnesium, zinc, bore, cobalt et/ou molybdone.
Ces oligo-elements aussi neo sont libérés que lentement et sous une forme dosée. Les oligo-éléments sont importants car les sols trop acides n'en contiennent plus du fait de la lixiviation, ou parce que le chaulage des sols pour lequel on a utilisé par exemple des chaux métallurgiques qui contiennent une forte proportion d'oxyde de calcium, les a immobili- ses et qu'ils ne sont donc plus disponibles pour les plantes.
Outre les substances dejä énumérées, la composition peut encore contenir des composes favorisant la croissance tels que de la quinetine (furfurylaminopurine-C10H9N5O).
<Desc/Clms Page number 6>
Ces substances de croissance evitent des troubles du métabolisme, en particulier des arbres.
La quinetine qui fait partie de la famille de la quinine, est l'une des principales substances-clµ de la biologie cellulaire des plantes. La quinétine favorise la division cellulaire des plantes, l'enra- cinement des boutures et empeche le vieillissement prématuré de parties de végétaux. Ceci est particulierement important pour la culture des plantes d'ornement.
La quinétine peut être utilisee en parti-
EMI6.1
culier en association avec l'acide indole-acétique qui est un accelerateur de croissance et qui, dans cette association, favorise une croissance lente, c'est-a-dire pas trop rapide, ainsi que les condi- tions du métabolisme, en ejnpechant les pertes de substances nutritives et un épuisement prématuré des plantes utiles telles que les arbres.
D'une maniere generale, il suffit d'ajouter par exemple 1 mg de quinétine a un litre de granulat.
La dolomite est utilisée de préférence dans des grosseurs de particules allant jusqu'à 0, 5 mm et doit contenir au minimum 40 % en poids de carbonate de magnésium. Elle sert principalement A exercer une action-tampon sur les sols trop acides et assure un approvisionnement à long terme en cal-

cium et magnésium.
Un grain de support enrobe d'acide humique et/ou de ses sels, d'acide silicique et de quinétine s'est révélé particulibrement avantageux. On a en effet observé une action synergique. des différents constituants qui contribuent A un amendement optimal du sol. \
L'efficacité du produit peut encore être

SPREADING PRODUCT FOR
THE SOIL AMENDMENT AND
PROCESS FOR ITS PREPARATION
The subject of the invention is a spreading product for soil improvement, in particular for improving the soil of cultivable agricultural land, greenhouses and / or potted plants.
To obtain an improvement in the structure
EMI1.1
re soils of this type, there are several systems, including peat fertilizer which is a fertilizer used in various forms. It used to be primarily brownish white peat that is found mainly in Central Europe and which is increasingly replaced by black peat. Peat is made up of 40 to 50% by weight of organic substances and water as well as 1 to 2% by weight of minerals (ash).
Due to the intensive use and high yields of soils and therefore the debt-improvement of their structure, on the one hand there is an increasing demand in particular of peat humic substrates, and on the other hand that the pursuit of the exploitation of natural peat deposits is no longer profitable In the long term.
Styropor aggregates are also used to improve the structure of soils, in particular to loosen them. Expandable polystyrene aggregates such as that known as "Styropor", however, only provide soil loosening and do not allow a simultaneous supply of nutrients.
<Desc / Clms Page number 2>
The present invention therefore proposes to produce a spreading product of the aforementioned type which makes it possible to dispense with the use of peat and with the help of which it is possible to improve the physical and chemical properties of the soils, and to favor the growth of plants taking root in these soils.
The invention has recognized that there are various natural porous substances having a large open porosity and which contain suitable additives, and which can therefore serve as support substances for introducing essential nutrients into the soil.
The invention likewise provides a spreading product consisting of a granular support substance, having a high porosity, in combination: with humic acid and / or its salts', the granular substance support preferably being coated with humic acid and / or its salts.
Thanks to the incorporation of humic acid or its salts in a porous support substance which is spread on the ground or incorporated therein, it is possible to obtain a uniform distribution of humic acid in the soil. Due to the extremely large open porosity of the expanded volcanic stone preferably used as a support substance, in particular perlite, humic acid is incorporated into the support substance for a certain time, so that it can be yielded continuously and slowly, on the surrounding soil.
Preferably, the porous, granular support substance is impregnated with humic acid or its salts, until the desired degree of coating is obtained, then it is dried. Humic acid is generally obtained from ltgnite and is a relatively inexpensive raw material that
<Desc / Clms Page number 3>
available commercially. This spreading product is particularly advantageous for soils with a particularly weak structure. Humic acid or its salts such as potassium or sodium salts serve as growth substances and improvers for soils with weak structure or poor in exchange.
Humic acid promotes the activity of living soil organisms, including earthworms; it contains no artificial additives, it improves the structure of the soil, directly by loosening heavy soils and indirectly by promoting the production of bacterial adhesives, allowing fine particles to gather in lumps. In this way, we obtain above all a love-
EMI3.1
soil bleaching. In addition, humic acid increases the water retention capacity of the soil. This is the result on the one hand, of the fixation of water in the organic substance, on the other hand of the improvement of the soil structure.
In addition, humus-humic acid substances improve the aeration of the soil, since a good lumpy structure produces larger pores, hence a better supply of oxygen to the roots and a problem-free escape of dioxide. carbon from the root zone. On the other hand, humic acid or its salts are able to accumulate nutritive substances on their surface in a form favoring exchanges, which is particularly important for weak clayey soils. In addition, due to their water-retaining power, humic acid and its salts mean that the soil can withstand periods of drought without degradation.
The combination of humic acid and perlite has this particular advantage that this expanded volvanic rock is an inorganic material, very light, of relatively large surface area,
<Desc / Clms Page number 4>
which means that the application allows the humic preparation to be distributed optimally in the soil. Perlite grains are used whose size is between 2 and 10 mm, and preferably between 2 and 5 mm.
In order to guarantee that the humic constituents are slowly transferred to the soil after spreading or incorporation, the spreading product may contain a binder. This binder can be a soluble glass (potassium silicate and / or sodium silicate). A potassium silicate is particularly advantageous since it also offers potassium which is a nutritive ion.
So that the spreading product remains "flowing", during the manufacturing process, silicic acid is added after impregnating the perlite with the solution consisting of soluble glass and humic acid (or its salts), while the spreading product is still wet. The chemical bonding of water has the effect of drying out the product which does not need to be specially dried. In addition, water glass or silicic acid has positive effects on the resistance of a whole series of cultivated and decorative plants. Particularly for cereals, silicic acid consolidates the supporting tissue, which has the effect of strengthening the stability of the stems and reducing lodging.
In addition, silicic acid promotes resistance to fungal diseases. Very often, the silicate inherent in the soil cannot be mobilized to a sufficient extent. However, the spreading product according to the invention also has the advantage of providing a soluble and easily mobilized silicate.
On the other hand, the spreading product can also contain a proportion of revitalizing substances.
<Desc / Clms Page number 5>
health, in particular dolomite, phosphates, various growth substances, precipitated silicic acid and / or magnesium carbonate.
The use of magnesium is most often necessary because the magnesium deficiency is particularly felt in plants fattened intensively with fertilizers containing nitrogen, phosphates and potassium. Such is often
EMI5.1
the case in particular for decorative plants. This is particularly true as plants lose magnesium as a result of their growth and due to leaching losses, especially on acid soils.
To prevent a lack of trace elements, the composition may also contain a mixture of oligo-! complex elements. Preferably, these elements are linked in a complex manner to EDTA (thylenediamine-tetracetic acid) in a form which can be easily assimilated by plants. The following trace elements can be used for this purpose: copper, iron, manganese, magnesium, zinc, boron, cobalt and / or molybdone.
These also neo trace elements are released only slowly and in a dosed form. Trace elements are important because excessively acidic soils no longer contain them due to leaching, or because the liming of soils for which we used for example metallurgical lime which contains a high proportion of calcium oxide, has immobilized them and is therefore no longer available for plants.
In addition to the substances already listed, the composition may also contain growth promoting compounds such as quinetine (furfurylaminopurine-C10H9N5O).
<Desc / Clms Page number 6>
These growth substances avoid metabolic disorders, especially of trees.
Quinetine, which is part of the quinine family, is one of the main substances-clµ of plant cell biology. Quinetin promotes cell division in plants, rooting cuttings and prevents premature aging of parts of plants. This is particularly important for the cultivation of ornamental plants.
Quinetin can be used in part
EMI6.1
culier in association with indole-acetic acid which is a growth accelerator and which, in this association, promotes slow growth, that is to say not too fast, as well as the conditions of metabolism, by ejnpechant nutrient loss and premature depletion of useful plants such as trees.
Generally speaking, it suffices to add, for example, 1 mg of quinetine to a liter of aggregate.
Dolomite is preferably used in particle sizes up to 0.5 mm and must contain at least 40% by weight of magnesium carbonate. It mainly serves to exert a buffer action on excessively acidic soils and ensures a long-term supply of
EMI6.2
cium and magnesium.
A support grain coated with humic acid and / or its salts, silicic acid and quinetine has been found to be particularly advantageous. We have indeed observed a synergistic action. different constituents which contribute to an optimal soil amendment. \
The effectiveness of the product can still be
<Desc / Clms Page number 7>
increased if, for example, magnesium carbonate is incorporated to promote the growth of plants and / or complex trace elements.
As a general rule, according to the invention, the spreading product contains, by weight, 70% and preferably up to 35% of humic acid and / or its
EMI7.1
I salts as well as possible other constituents of coating by. ratio to the total pea of the spreading product.
To prepare the spreading product, according to the invention, the open-pore granular support substance is mixed in a kneader with fluid humic acid and / or its salts with possible other components until impregnation at the value choose from the free surface of the support substance. Impregnation can be obtained by spraying if necessary with silicic acid.
