Definitions
- the present invention relates to a method for producing a biological growth promoter for liquid phase plants based on vermicompost and percolate, and a production device for implementing such a method.
- the root system of plants develops to take in the soil or in its environment nutrients essential for the growth of the plant, namely mainly nitrogen, phosphorus and potassium designated by the acronym "NPK”.
- Bacteria that are beneficial to root systems, which are therefore essential for promoting plant growth, are produced mainly by living fauna in the soil, especially with mites, with droppings from the digestive system of insects, and more particularly with manure dung. earthworms.
- earthworms are one of the first producers, if not the first producer, of bacteria through their digestive system, the vermicompost and percolate they emit constituting indeed biological growth activators particularly efficient plants.
- a known type of installation performing a vermiculture consists of a treatment plant and recovery of livestock effluents, including an effluent methanization unit performing a treatment of biogas obtained , a cogeneration unit delivering electricity and heat from these biogas, a hydroponic unit of micro-algae in photo-bioreactors fed by a part of the liquid phase of the raw digestate produced by the methanation and a separation system capable of delivering a liquid digestate phase and a solid phase comprising the digestate sludge.
- Such an installation is remarkable in that it also comprises a macrophyte culture unit fed by the water emerging from the microalgae culture unit and by another part of the liquid phase of the raw digestate produced by the plant. methanisation, as well as a vermiculture unit fed by harvesting macrophytes and by sludge constituting the solid phase of the raw digestate of the methanation.
- the digestion by the culture of the earthworms is to raise worms on a compost forming an organic support regularly watered by water, thus maintaining the moisture essential for the survival of the worms, to realize a biological process which favors the digestion of these materials.
- earthworms of the "Eisenia andrei” type also called “California worms", which are fond of organic matter, are used and which are therefore well adapted for this function.
- the earthworms release from their digestive tract an odorless dark brown liquid drop, called percolate, which is very rich in mineral and organic elements, but also very rich in anaerobic bacteria.
- the percolate is therefore an excellent "fertilizer” that can be used as a liquid fertilizer, but on the condition however to dilute it with a volume in ten volumes of water because this product is very concentrated.
- the percolate also has the disadvantage of not being stored too long, because it loses much of its nutritional capacity for plants.
- vermicompost harvested which comes from materials digested by earthworms (bacteria, mites for example), it is a pasty product, dark brown, resembling genoise, which is generally collected under the layer of to (litter) in vermicomposter bins.
- vermicompost is essentially rich in aerobic bacteria from the digestive system of worms constituting an essential part of the composition of soil humus, but also nitrogen, phosphorus, magnesium, copper, zinc, iron and manganese, and as such the vermicompost is used both to stimulate the growth of plant roots, by covering their needs in nutrients, only to stabilize soils by improving their aeration, drainage, and their ability to react against acid rain insofar as the vermicompost constantly has a neutral action.
- vermicompost is currently mainly used in a dehydrated form, and this product loses almost all its bacteria.
- the present invention is intended to overcome all the disadvantages of the prior art. While the two aforementioned materials have never been proposed for marketing in an associated form, the invention proposes to combine them by the implementation of a very particular process, this method making it possible to obtain a final product of activating plant growth that is easy for farmers to make and use.
- the obvious advantage of combining the two abovementioned materials is that of bringing the two types of bacteria (aerobic and anaerobic) to the soil in a single operation.
- the invention thus proposes for this purpose a process for producing a biological growth activator based on vermicompost and vermiculture percolate in the liquid phase, this process being remarkable in that, after depositing vermicompost in a reactor. and percolate forming a compound, it comprises a step of solubilizing vermicompost in the percolate by injecting air inside this compound.
- An advantage of this method of producing an activator is that the injection of air into the compound, particularly into the Vermicompost more solid deposited at the bottom of the reactor, performs a mixing of this compound making a mixture and solubilization of the vermicompost in the liquid percolate, together with a homogenization of this compound. In other words, by mixing the two materials and solubilizing the vermicompost in the percolate, solubilizing at the same time aerobic bacteria vermicompost in the percolate.
- the injected air forms bubbles releasing oxygen in the solution, this gas is obviously essential for the survival of aerobic bacteria.
- This produces a product forming a biological growth promoter whose quality is high thanks to the density of the bacteria contained therein.
- the method according to the invention consisting in solubilizing vermicompost in percolate has nothing in common with that of preparing the fertilizing product which is commonly called “compost tea” or “vermicompost tea” or still “vermicompost tea”.
- the compost tea as described for example in the international application WO 2005/067550, in the Russian patent RU 2,253,641 or in the Dutch patent application NL 1984/03274, is a fertilizer product obtained simply by dissolving the vermicompost in water, possibly in the presence of chemical additives.
- Compost tea can suspend or even solubilize vermicompost aerobic bacteria in water, but it does not plan to mix vermicompost with percolate.
- the production method according to the invention may further comprise one or more of the following characteristics, which may be combined with each other.
- the method carries out the step of solubilizing the vermocompost in the percolate with a compound comprising a proportion of vermicompost of between 30 and 70% of the total mass of this compound.
- the compound may comprise a proportion of vermicompost of between 40 and 60% of the total mass of this compound, this proportion of vermicompost may also be close to 50% of the total mass of said compound.
- the solubilization step is conducted according to the process according to the invention for a period of between 12 and 24 hours.
- the method according to the invention proposes to perform the injection of air by forming a jet of bubbles inside the compound.
- the process can perform a mechanical stirring of the compound.
- the process comprises a step of separating the residual solid present in the biological growth promoter.
- the process according to the invention may further comprise a step of adding water to the percolate / vermicompost compound in order to increase the solubilization capacity of the second in the first of these two elements.
- the method may provide an additional step of providing sugar to said final compound.
- the invention also relates to a device for producing biological growth promoters which is remarkable in that it comprises means implementing a production method comprising any one of the preceding characteristics.
- the aforementioned production device comprises a reactor having a tank which is thermally insulated.
- the device comprises a mobile mechanical system, or a device for injecting air bubbles, capable of stirring the compound.
- the third subject of the invention is a biological growth promoter based on vermicompost and vermiculture percolate in the liquid phase, this activator being remarkable in that it is obtained by carrying out the process corresponding to any of the features set forth above.
- FIG. 1 is a diagram showing different stages of a production line comprising the production method according to the invention
- FIG. 2 is an example of a reactor implementing this production method
- FIG. 3 is a diagram of a final separator treating the product obtained by this production process
- FIG. 4 shows another example of a reactor capable of implementing the production process of biological growth promoters according to the invention.
- FIG. 1 schematically illustrates a first step 2 of a production line comprising vermiculture which produces vermicompost 4 and a percolate 6 in the liquid phase.
- the vermiculture can be part of an installation in accordance with that described in the document of the prior art referenced in the preamble of the present application. patent.
- any other vermiculture plant producing vermicompost 4, rich in aerobic bacteria, and a percolate 6, rich in anaerobic bacteria may be suitable.
- a second subsequent step 8 of storage and preparation the vermicompost 4 and the liquid phase percolate 6 obtained as indicated above are deposited one is the other in a reactor 24 (see Figure 2) receiving at inside a flow of air 10 capable of performing a permanent mechanical mixing of these two elements, and this in order to solubilize the pasty product that is the vermicompost in the liquid percolate and thus transform the starting compound to obtain a compound now liquid.
- the proportion of vermicompost 4 introduced into the reactor represents between 30 and 70% of the total mass of the compound, the remainder being formed by percolate 6.
- the proportion of vermicompost 4 is between 40 and 60%, and ideally it can to be 50% of the total mass of the compound consisting simply of vermicompost and liquid phase percolate.
- the air flow 10 forms bubbles in the compound, bubbles which stir and mix the solution, while oxygenating it to keep alive the aerobic bacteria, mixing the compound, provided in the reactor through the air flow , can last between twelve and twenty-four hours, depending on the relative quantities of vermicompost and percolate, which allows to obtain an optimal solubilization of vermicompost 4 in the percolate 6. The higher the proportion of vermicompost will be higher and the necessary time at its solubilization in the percolate will be high.
- the operator in order precisely to increase the solubilization capacity of the percolate, may add water to the percolate / vermicompost compound in the proportion of 1 to 30% of the total volume of the new compound percolate / vermicompost / water thus formed.
- a crude liquid activator 16 is obtained, which is advantageously treated by a third step 18 in a separator delivering a liquid forming the biological growth promoter 22, easy to implement for the end users, and a residual solid. Representing about 5% of the total mass which does not solubilize in percolate 6.
- the residual solid obtained by pressing through a grid having meshes of about 0.5 mm in diameter can be marketed to form a soil amendment product.
- FIG. 2 represents a reactor 24 - able to carry out the second stage 8, which reactor comprises an isothermal cylindrical tank 30, comprising a double wall with an intermediate insulator, arranged horizontally on feet 26.
- the top of the tank 30 is provided with a hatch 32 allowing the introduction of vermicompost 4 and percolate 6, or even that of water in case of percolate excessively charged with bacteria.
- the base of one end of the tank 30 comprises an outlet valve 34 allowing, after a reaction time, the extraction of the crude activator 16 comprising the vermicompost 4 in solution in the percolate 6.
- the tank 30 is also provided at one end with a system 36 for the permanent injection of an intensive jet of bubbles, injecting at the base of the compound 38 the air flow 10 which, in addition to the oxygenation of the bacteria, generates a constant movement inside this compound to achieve the solubilization of vermicompost 4.
- the intensive bubbling system can be of the order of fifty liters / minute for five m 3 of compound to be treated.
- the tank 30 may comprise on the top a system 42 for permanent mechanical stirring comprising an electric motor driving mixing blades 40.
- each of the blades 40 of the stirring system 42 may be provided with an inlet and an air outlet, always for the purpose of generating a permanent movement in the compound.
- the injection of air can be provided by saccades, or continuously.
- FIG. 3 shows a separator 50 comprising along a same axis, from a side conventionally called rear side, a geared motor 52, then a worm 56 fitted into a cylindrical body 54 disposed at the end of this geared motor.
- the cylindrical body 54 has a rear hopper 64 receiving the raw activator 16 coming from the reactor 24, activator which is then driven by the worm 56 forward. By its rotation, the worm 56 presses the raw activator 16 forward against a plug 58 closing the entire front section of this screw.
- the pressure force on the raw activator 16 carries out a wringing of this material, which releases a liquid passing through a filtration grid 60 fitted below the worm 56, having meshes having for example a section passage of 0.5mm.
- the biological growth promoter liquid 22 which is recovered by a lower hopper 62 disposed below the filtering grid 60, and on the other hand the residual solid 20 which is evacuated after each opening. or temporary erasure of the cap 58.
- Such a plug 58 may for example be formed of two pivoting doors, normally closed in order to completely obstruct the front exit of the body 54, doors which open automatically by counterpressure beyond a certain constraint exerted by the residual solid mass 20, as and when the formation of this cluster.
- the cap 58 can also be made from a diaphragm.
- the biological growth promoter 22 it is possible to use the biological growth promoter 22 to coat seeds before seeding.
- the biological growth promoter 22 can be used directly at the time of sowing, with a capillary giving a flow of the product on the seeds being deposited.
- the dispensing of the liquid product is easy and simple, in particular with a dosing pump which can be integrated on the drill.
- FIG. 4 shows another example of a reactor 46 whose isothermal tank 30 is in the form of a silo.
- the tank 30 rests for example on a foot that encloses the injection system of the jet of bubbles 10.
- the tank 30 is closed at its upper part by a plug 44, which cap is removable to allow the introduction into the tank vermicompost 4 and percolate 6, or even that of water, desired if it is necessary to increase the solubilization capacity of the percolate, or that of sugar, in the form of molasses, in order to obtain a final product whose storage time would be significantly increased.
