Description

FIELD OF THE INVENTION The present invention relates to a stable suspension fertilizer composition containing nitrogen, phosphorus, potassium, field and microelements, active ingredients in agriculture and the chemical industry, in which the stabilizer is a by-product of the spirit industry "VINAS".

The field of application of the aqueous suspension fertilizer composition of the present invention is agriculture.

In the agricultural sector, and especially in crop production, the structure of the means of production has changed significantly, mainly based on our results over the last 10 years. Chemicals, so far, have included processes using other means of production, and nutrient supply has been chemically decisive. As a result, the value of chemicals in the main crop production sector is now significantly higher than the value of fixed capital goods throughout agriculture. Accordingly, the efficiency of chemicals plays a crucial role in determining the cost and effectiveness of crop production.

The above mass of chemicals has now increased proportionally above the average plant level to the technical optimum level for certain chemicals operations. Thus, in particular, the efficiency of transportation, manipulation and storage as a business activity is far below the technical optimum.

At the same time, chemicals are handled as current, and about 80% are stored freely, much of it uncovered. As a result, solid fertilizers are expected to have a 10-30% loss of active ingredient nationwide. However, this "lost chemical mass" is not being destroyed, it is polluting our environment.

The professional mechanization of solid fertilizer application is not solved because it is inadequate to dispose of mixed fertilizers at the currently applied doses using a fly disc principle machine.

In countries with advanced agriculture, the use of liquid (slurry) fertilizers has accelerated in the last 10 years. so in the United States, Denmark, France, Czechoslovakia. Nutrient supply technology based on soil analysis, modern crop production, adaptation to site conditions, and the use of plant-specific fertilizers with high content of active substances are required.

The formulations should be suitable for incorporation into energy-efficient tillage technology that preserves soil moisture. Suspended fertilizers are best suited to this requirement.

Advantages of suspension fertilizers over solid fertilizers:

- the active ingredients can be sprayed from one another

- evenly applied

- their local application is simple, well controllable

- the active substances are perfectly water soluble

- excellent mixing with herbicides and soil conditioners

- may be combined with irrigation and biological growth promoters

- the application can be effected with high power

- application work can be linked to other work phases10 - can be brought into depth according to the needs of the plant - time of work can be optimized - high degree of mechanization of nutrient replenishment - plant protection machinery can be used - can be stored without losses - meet the environmental and landscape aspects

The disadvantages of the liquid fertilizers mentioned above are the drawbacks of the temporary storage solution in the manufacturing plants and the user's mg plants, as compared to solid fertilizers, since special storage space and equipment are required for temporary storage, but these disadvantages are diminished by liquid (suspension) fertilizers. advantages.

Suspended fertilizers may be prepared from a variety of solid, liquid, gaseous feedstocks, which may be solutions of various nitrogen contents, e.g. NH4 OH, Nitrosol, Hydronite, etc. or solid starting materials, e.g. Carbanides, mono-ammonium phosphate MAP), potassium salts and gaseous e.g. ammonia.

In practice, there may be several days of discrepancy between the production and application of suspension fertilizers. It is a fundamental problem that the components of the manufactured suspension fertilizers settle during storage and cannot be brought into suspension state after settling, thus significantly reducing their further usability. Various stabilizers are used to overcome the sedimentation problem, which requires the constituent elements of suspension fertilizers to be kept homogeneous for several days.

Among the known stabilizing agents used in Hungary:

- ON-bentonite and superphosphate stabilizer developed by Veszprém Heavy Chemical Research Institute.

- A stabilizer with a combination of ON-bentonite and PW 101 developed by the Chemical Company of Peremarton.

- Activated illite stabilizer developed by the Budapest Chemical Works.

- Bentosolone -82 stabilizer produced at the Madi plant of the National Ore and Minerals,

BN sludge stabilizer from Borsodnádasd,

Attapulgit 150 stabilizer, purchased from the US by the Bábolna Industrial Corn Production System.

U.S. Pat. No. 3,148,970 discloses a colloidal material of from 1 to 20% by weight as a stabilizer which is added in soluble form to the suspension to be stabilized with magnesium, calcium, barium or aluminum ions.

In U.S. Patent No. 3,234,004, a colloidal attapulgite is used in an amount of 0.25% by weight as a stabilizer.

The United Kingdom Patent No. 948,920 discloses the reaction product of 0.1% by weight of formaldehyde with a sulfonic acid.

In addition to the advantages of the above-described stabilizers, they have the disadvantages of being either too expensive or available as an imported feedstock, or that the mechanism of action of some of the stabilizers is imperfect because of their sedimentation.

Of the many industrial by-products that are available and stabilized on the domestic market, many preparations have been tested e.g. alumina ₄ θ ri red sludge, pharmaceutical by-products ^w eg potassium chloride, etc.

During our investigations, we have discovered that the alcohol and yeast industrial by-product known as the "VINAS" fantasy is best suited to stabilize the suspension fertilizers we have described. j 5

The present invention is based on the discovery that if the NPK active fertilizer suspension fertilizers are stabilized at a ratio of 5-15% by weight of the "VINAS fiber", a very stable suspension fertilizer is obtained over a long period of time.

Advantageous effects of the present invention include NPK and meso-micronutrient suspension fertilizer compositions.

- The inventive stabilizer and the resulting suspension fertilizer compositions provide a homogeneous fertilizer between production and application that is reassuring.

- After several days of production, there is minimal but not significant separation, which disappears immediately after the slightest shaking or mixing, and the homogenous suspension fertilizer is again homogeneous.

The advantage of this is that if the suspension fertilizer composition remains in the transport vehicle, any separation that occurs after several days is immediately eliminated as the vehicle is moving or, in the case of separation in a storage tank, by simple mixing manipulation, a stable suspension fertilizer is obtained.

(Separation is recognized by the appearance of a watery layer on the upper part of the suspension after 10 to 15 days of prolonged exposure, but no sedimentation. Separation is completely eliminated by minimal shaking or mixing manipulation.) application to the field, this is the best result of the known suspension fertilizers.

The following examples illustrate the laboratory and commercial scale preparation of the slurry fertilizer composition of the present invention:

The NPK ratio is 1: 0.8: 1.3. The slurry fertilizer composition remained homogeneous for 48 hours and no sedimentation was observed.

Example 2

Laboratory preparation:

To 336 mL of water was added 470 mg MAP, followed by 173 mL NH ₄ OH followed by a 3 min neutralization break, 305 mg 60% potassium salt and 100 mL vinasse followed by vigorous stirring of the fertilizer composition for 5 min .
