Abstract

Disclosed is a process for the preparation of keratin fertilizer with the addition of humic acids in colloidal form and a fertilizer produced in this way, which is obtained by treating the feathers from a poultry plant, e.g. chicken, goose, duck, ostrich, and bristle, bovine hair, horn and hoof, pig spokes, fish remnants, hair, hair, skin remnants, hair, sheep wool, camel wool, pig bristles and cattle, kangaroos, bovine, camel, kangaroo bones, bone from any poultry and pig bones. Neutralization in the fifth step is performed with citric acid (C3H5O. (COOH) 3) or acetic acid (CH3COOH) or formic acid (HCOOH).

Description

The invention relates to a process for the preparation of a keratin fertilizer with the addition of humic acids in colloidal form and a keratin fertilizer with the addition of humic acids.

BACKGROUND OF THE INVENTION

In the published Slovak patent application PP 1539-2003 is described an additive for fertilizer containing organically bound nitrogen for the production of granular or liquid fertilizer, which consists of a mixture of unprocessed or granular treated corners and digging bovine with a moisture content of up to 12% by weight, containing up to 18% organically bound nitrogen of a protein nature, the granules of treated horns and hooves of cattle being from 0 to 12 mm. At the same time, the present invention provides a process for the production of an organic nitrogen fertilizer additive for the production of a granular or liquid fertilizer, according to which the mixture is poured into a process vessel, for example a reactor. To the mixture is added 100% potassium hydroxide (KOH) in a weight ratio of min. 1: 2 to the amount of mixture to be treated and the contents of the process vessel are poured into 200 l of water. The mixture may be stirred or heated in the liquor bath. After dissolution, it is neutralized by the addition of 50 liters of 85% phosphoric acid. After neutralization, it can be enriched with other nutrients such as NO 3, Mg, Fe, Co, B, Mn, Zn, Cu and the like. Finally, the solution was quenched into 1 000 liters of water (H ₂ 0).

In terms of plant nutrition, the nitrogen content of the soil is the most important, although the presence of phosphorus and sulfur also has a positive effect. Since it is organically bound in the soil, it is released gradually. The decomposition of the albuminoid substances first changes to ammoniacal (NH4 ⁺⁾ and further oxidation to the nitrate (NO3) form.

The fertilizers produced so far usually have a low nutrient content. The nitrogen present is in nitrate form, to a lesser extent ammonium. In extracorporeal application, amidic nitrogen acts less necrotic on the plant tissue. In combination with other forms of nitrogen it allows for better utilization of this nutrient by plants.

Furthermore, a process for producing compost according to the Hungarian invention, patent no. 205 336 A, high in organic matter with a stimulating and alternative ameliorative effect, using an additive containing keratin and pig manure. The production process consists in separating the liquid pig manure into a solid and a liquid part by phase separation. The solid is mixed with keratin-containing substances (fur, horn). The base material thus formed contains 5-50% keratin material. The base material is mixed with 2-8% slaked lime, 5-10% alginite, 5-10% riolite tufa and 10-20% peat. The mixture obtained, taking into account its total weight, is further homogenized after addition of 10% keratin additive. The well-mixed compost is then granulated. The gravity of the tomb is 65-80% with a liquid containing 5-20% dissolved keratin. The tomb is stirred after 1-2 months.

According to the Hungarian invention, no. No. 205 739 A, a matrix is known for slowly degrading biofertilizer enriched with trace elements and with a high organic content using keratin. The process for producing this mixture is as follows. Keratin-containing substances are mixed with slaked lime. In an autoclave, with stirring, they are subjected to a heat treatment with a simultaneous pressure change. The hot meat is filtered and filled into containers. The organic fertilizer mass thus obtained is supplemented with trace elements as necessary.

Said fertilizers with keratin additives are technologically demanding, time consuming and require a certain time before its application and at the same time heat treatment increases the costs of its preparation.

SUMMARY OF THE INVENTION

According to the present invention, a process for the preparation of a keratin fertilizer with the addition of humic acids in colloidal form and a fertilizer produced by this process, which is obtained by processing feathers e.g. of chickens, geese, ducks, poultry ostriches and bristles, bovine fur, horn and hoof hair, pig rays, fish residues, hair, hair, skin residues, hair, sheep wool, camel wool, pig and bovine bristles cattle, kangaroos, beef, camel, kangaroo, bone from any poultry and pig bone (hereinafter a mixture of organic raw materials).

Prior to the commencement of the production process, the delivery of a mixture of organic raw materials in transport containers is carried out by an approved veterinary administration and performed by a valid disinfection by an authorized company. The mixture of organic raw materials is then poured from the container into a suitable place.

The processing of the organic raw material mixture is carried out immediately after the arrival at the designated site in order to avoid undesirable qualitative changes therein.

First, the weighed mixture of organic raw materials is placed in the reaction vessel, the reaction vessel being made of a material resistant to concentrated alkalis with the possibility of closing, stirring, with outlet and inlet valve and equipped with a self-draft through a carbon filter.

Potassium hydroxide (KOH) is then added to the weighed reaction vessel in proportion to the weight of the organic raw material mixture.

Water is then added to the reaction mixture to be prepared in proportion to the weight of the organic raw material mixture. Before adding water, the reaction vessel should be closed and water must be added at once, as the mixture is heated very strongly.

Subsequently, the reaction vessel decomposes in the mixture of organic raw materials for 20 hours. In a sealed reaction vessel, stirring occasionally for 20 hours, the mixture of organic raw materials is dissolved by treatment with potassium hydroxide (KOH).

Citric acid or acetic acid or formic acid is then added to the prepared mixture in the reaction vessel in proportion to the weight of the organic raw material mixture. After dissolving the organic raw material mixture, the prepared mixture is neutralized with 99% citric acid or 85% formic acid or 80% acetic acid. This can be added directly to the reaction vessel with vigorous stirring. In this step, the reaction associated with short-term foaming takes place.

The pH of the mixture to be prepared is then measured. A sample is taken from the neutralized mixture to be prepared, cooled to 20 ° C and its pH measured. The desired pH should be in the range of 6.5 ± 0.2. In case of major deviation, the pH should be adjusted by adding 99% citric acid or 85% formic acid or 80% acetic acid or potassium hydroxide.

Furthermore, magnesium sulfate, iron sulfate, boric acid, manganese sulfate, zinc sulfate, copper sulfate, ammonium molibdate, calcium nitrate are added.

Then the distribution of the prepared mixture from the reaction vessel into the prepared transport vessels takes place, the distribution being dependent on the weight of the potassium hydroxide contained in the prepared mixture. The neutralized feed mixture being the " fertilizer base " is separated from the reaction vessel by recalculation into the prepared transfer containers by means of a drain pump through a suitable filter while stirring the mixture being prepared (fertilizer base) in the reaction vessel.

Then the preparation of the diluted mixture to be prepared. Transport containers are waterproof closable containers with the possibility of mixing. In such a container with the prepared mixture (fertilizer base) water is added and mixed thoroughly.

The tenth step involves the addition of humic acids to the diluted preparation of the transport container to form a finished keratin fertilizer with the addition of humic acids in colloidal form.

Keratin fertilizer with the addition of humic acids in colloidal form, containing a mixture of organic debris, potassium hydroxide, phosphoric acid, magnesium sulfate, iron sulfate, boric acid, manganese sulfate, zinc sulfate, copper sulfate, ammonium molybdate, calcium nitrate, humic acids and water.
