Abstract

A granulated organic and organomineral fertilizer supplemented with biological additive and process for the production of granulated organic and organomineral fertilizer supplemented with biological additive is physically presented in the form of granules (G), having its formulation defined by the combination of organic and mineral matter (N,P,K), to which it is added, in addition, a bioburden in the form of bacteria, fungus and yeast that are selected to crops of interest, whether grasses, legumes, monocotyledons and dicotyledons, the granules (G) receive the bioburden at the time of its granulation; the selection of bioburden to be included in granules (G) is established according to the soil and crop analysis to be cultivated.

Claims

3. A process for production of granulated organic and organomineral fertilizer supplemented with biological additive, the process comprising: pre-cleaning a raw organic matter; screening the pre-cleaned raw organic matter with a rotating screen station; fragmenting and homogenizing the screened raw organic matter with a mill, to provide processed organic matter; mixing the processed organic matter with a charge of N, P, K to provide a processed organomineral matter; granulating the organomineral matter with addition of a liquid comprising the biological additive to provide granules; drying the granules at humidity rate from 10% to 15%; cooling the dried granules in a cooler to about 50? C., wherein the cooled granules have granulometry of about 1 mm.

4. The process of claim 2, wherein the crop is selected from the group consisting of grasses, legumes, monocotyledons and dicotyledons.

Description

BRIEF DESCRIPTION OF THE DRAWING

(1) This patent application will be described in detail with reference to the depicted in the FIG. 1, which illustrates a schematic view of a flowchart with regard to the steps of producing a granulated organic or organomineral fertilizer containing biological additives in its formulation.

DETAILED DESCRIPTION OF THE INVENTION

(2) Before the state of the art afore described, it was developed the object of this invention patent application, which proposes an organic and/or organomineral fertilizer in granular form with the presence of biological additives in its formulation.

(3) Technological innovation addressed by this invention patent application is based on the possibility that each granule (G) of the fertilizer containing organic matter, minerals (whether micro and/or macro) and having in its formulation biological additives (whether bacteria, fungi and yeasts), which will be specially selected for crops of interest (whether grasses, legumes, monocotyledons and dicotyledons).

(4) To a perfect understanding of the present object of the invention patent application, it is necessary to describe the process of obtaining granulated organic and organomineral fertilizer additive with biological matter such as already provided for in state of the art, and taking as a base the flowchart of the FIG. 1.

(5) In the aforementioned FIG. 1, the raw organic matter 1 is fed to a conveyor 2 which leads to a screen 3 to be subjected to a pre-cleaning step, being that, after this pre-cleaning step, the raw organic matter is conducted at a rotating screens station 4, where the raw organic matter already screened is led to a mill 5, where this raw mater is fragmented and homogenized as regards its granulometry, such granulometry that is about 1 mm.

(6) After exiting the mill 5, the raw organic matter 1 is now defined as processed organic matter 1, being then sent to a mixer 6 which operates jointly with a means of stock 7, which is stored the charge of N, P, K and with a storage reservoir 8 of biological additives, this reservoir 8, wherein the liquid consisting of the bioburden to be administered to G granules at the time of its production is stored.

(7) The storage reservoir 8 is bond to a fluid feed line 9 that presents ramifications 9A for each one of the granulating equipment 10.

(8) In the mixer 6, processed organic matter 1 is combined with a suitable proportion of N, P, K, then passing to be denominated as the processed organic matter aggregated of NPK 1, being then sent to the granulating equipment 10 arranged in a processing area 11, wherein during the granulation step that takes place according to the conventional process, there is also the administration of the bioburden by applying a liquid additive biologically loaded and which is contained in the storage reservoir 8 being driven by the fluid feed line 9 to each of the granulating equipment 10.

(9) The matter's bioburden fed to the granulating equipment (10) is defined according to the soil and crop analysis to be cultivated.

(10) By leaving the granulating equipment 10, the fertilizer already in the form of suitably additive granules G is then sent to a dryer 12 where its humidity ratio in set within preset parameters, such humidity rate is 10% to 15%.

(11) By leaving the dryer 12, the granules G are then sent to a cooler 13 and when it reaches the right temperature, which is around 50? C., granules G already dry and cold are sent for shipment 14.

(12) The aggregation of the biological additives for granulation in the organic and organomineral fertilizer aims six key fronts, namely: Increase of the efficiency of mineral fertilizers; Reduction of the environmental impact; Positive physiological effects in the plants that reduce or eliminate the abiotic and biotic stresses of the plants; Gradual release of the nutrients to the soil; Simplification of the production process (avoiding subsequent processes such as coating or spraying of the biological additives); Reduction of the productive cost.

(13) The addition of organic additives in processes where there is the use of high pressure and temperature (such as, for example, pelletization) may jeopardize the survival of the microorganisms in the biological additives. Thus, the granulation proves to be a viable and safe alternative (process without the presence of pressure or temperature).

(14) The innovation of this process, such as it is shown in the FIG. 1, consists on including biological additives with specific combinations to certain crops in the organic fertilizer and/or organomineral formulation through industrial granulation process.
