The invention relates to non-waste producing organic liquid humic fertilizers for agriculture on the basis of peat humic acids, macro - and micronutrients to improve soil fertility, improve the growth and development of plants, feeding various crops.

There are many technical solutions, revealing the methods of obtaining liquid humic fertilizers by treating humified material (water-peat slurry, peat, sapropel, compost, humus horizons of different soil types and other) alkaline reagent, upholding the suspension and separating the liquid fraction, adding substance - source elements of mineral nutrition of plants (As of the USSR №442180, IPC C05F 11/02, 1972; U.S. Pat. Of the Russian Federation No. 2071459, IPC C05F 11/02, 1993; U.S. Pat. Of the Russian Federation No. 2015949, IPC C05F 3/00, C05F 11/02, 1991; U.S. Pat. Of the Russian Federation No. 2178777, IPC C05F 11/02, 2000).

A method of obtaining liquid humic fertilizer comprising mixing humic-containing components with 0.5 - 2% aqueous solution of caustic potassium, upholding the suspension, separating the liquid fraction, the introduction of trace elements and elements of mineral nutrition of plants, and mixing humic-containing component with an aqueous alkali solution at a ratio of 1: 11-13 and sedimentation is carried out alternately at least two times at a temperature of not less than 15°C (patent P is No. 2181710, IPC C05F 11/02, C05F 3/00, 2000, prototype)

A disadvantage of the known technical solutions, including the prototype, is the need of enrichment obtained liquid humic fertilizer elements of mineral nutrition of plants, which leads to increased cost and complexity to the manufacturing process of liquid humic fertilizer for agriculture.

The problem solved by this invention is the development of a method of producing a liquid humic fertilizer, which is simple and low cost, extends the range of liquid humic fertilizer for crop production and agriculture.

The technical result obtained from the solution of the set task is to reduce the cost of production of liquid humic fertilizers and, therefore, the cost of the target product is a liquid humic fertilizer, expanding the range of liquid humic fertilizer and can be used in agriculture to improve the growth and development of plants, as well as to activate soil microbial processes. Use as humic-containing material waste production of liquid-phase BioWare for crop production and agriculture - draft - does not require the cost of purchase and can be attributed to the production of liquid humic fertilizer to ut the recycling of production waste liquid BioWare for crop production and agriculture, and manufacture of liquid-phase BioWare for crop production and farming to non-waste producing organic liquid humic fertilizers.

Put in the invention the problem is solved by the fact that in the method of producing a liquid humic fertilizer comprising mixing humic-containing material with 1.5 to 2.0%aqueous solution of caustic potassium, upholding the suspension and separating the liquid fraction, and mixing humified material with 1.5 to 2.0%aqueous solution of caustic potassium and upholding suspension of exercise three times as humic-containing material use production waste liquid BioWare for crop production and agriculture, providing for the fermentation process within 5 days tortonese mixture in a ratio of components 50x50 with the addition of wood ash in the amount of 3 wt.% followed by extraction with 1%solution of potassium phosphate solid phase fermentation and filtering the extracted mass, which receive the sludge, which is a waste product of liquid-phase BioWare for crop production and agriculture, the active principle of which is carbon, organic matter, Corg- 30,0...40,0, wt.%, and, in addition, including macronutrients: nitrogen (Ntotal- 1,15...1,80, wt.%; phosphorus P2 O5- 1,4 2,2..., wt.%; potassium K2O - 1,0 2,3..., wt.%; calcium CaO - 1,6 1,1..., wt.%; magnesium MgO - 0,2...0,8, wt.% and trace elements, at least, boron, copper, cobalt, manganese, selenium, silicon, while stirring humic-containing material with 1.5 to 2.0%aqueous solution of caustic potash is produced three times, each time at a ratio of 1:10 with a speed of 20 rpm, at a temperature of 60°C for at least 1 hour, and the defense after each stirring at 60°C for 2 hours, followed by the separation and unification of the supernatant liquid.

The precipitate, which is a waste product of liquid-phase BioWare for crop production and agriculture, and a high level of biogenic features, nutrition and physiology, is a wet (W 70-80%) homogeneous mass of dark brown color without the unpleasant smell. Manufacture of liquid-phase BioWare involves fermentation for 5 days tortonese mixture in a ratio of components 50×50 with the addition of wood ash in the amount of 3 wt.% followed by extraction with 1%solution of potassium phosphate solid phase fermentation and filtering the extracted mass, which receive the sludge, which is a waste product of liquid-phase BioWare for crop production and agriculture. As the primary and the initial raw material for liquid-phase BioWare and accordingly, the sludge used lowland or transitional peat and manure of cattle, and the technology is focused on the selection and preservation of biogenic component, which is reflected in the choice of the basic biological conversion process - fermentation and moderate temperature conditions (37-55°C). However, this method does not allow you to maximize the use of internal nutrient potential of peat, in particular not is the selection of humic substances. Therefore, the organic matter of sludge in the production of liquid bio also is not activated and it should be considered as a humic-containing material for further conversion into liquid humic fertilizer. In the sediment contains carbon organic matter Corg- 30,0...40,0, wt.%, all the basic elements of nutrition: nitrogen (Ntotal- 1,15...1,80, wt.%; phosphorus P2O5- 1,4 2,2..., wt.%; potassium K2O - 1,0 2,3..., wt.%; calcium CaO - 1,6 1,1..., wt.%; magnesium MgO - 0,2...0,8, wt.%, trace elements (at least Mn, B, Si, Mo, Cu, etc. - Protocol analysis of Federal state budgetary institution of science of the order of Lenin and the Order of the October Revolution of the Institute of Geochemistry and analytical chemistry. Vernadsky, Russian Academy of Sciences), a large number of agronomically beneficial microflora (108...109COAG), presents physiologically active substances (enzymes, vitamins), common forms of carbon and nitrogen are in the optimal ratio (C:N)~22, i.e. contains all the basic components, can have a positive influence on many soil processes and the processes of growth and development of plants.

Sludge treatment potassium hydroxide enables humic complex peat, having the properties of physiological activity. The degree of activation is expressed in the increased content of mobile humic substances in the form of potassium humates are plant growth regulators. Simultaneously, the KONA is a source of potassium, as one of the components of mineral nutrition of plants. In addition, caustic potassium relatively cheap compared with other alkaline reagents used for the selection of humates.

Set [T.A. Kukharenko, Saepio the basic technology of production of humic acids, 1957] and experimentally confirmed in the example above the sediment that for the most comprehensive and economically viable extraction of humic acids requires three sequential extraction of the alkaline reagent. For once extracted the bulk humic acids, with a further extract obtained additional humic acid.

Set [Author's certificate the construction of the USSR №1323555, CL. C05F 11/02, 1987]that the processing of peat 1,0-2,5%solution of caustic potassium stand out the most pure humic acid containing the largest number of active functional groups, which are plant growth regulators. When using the concentration of KOH, 0.5%solution contains an insufficient amount of potassium. This leads to the fact that in complex fertilizer you also have to add fertilizer to meet the plants in potassium. With increasing alkali concentration to 3% and above in the selected humates there is a decrease in the content of active functional groups, the increase in ash content. This is because more concentrated alkaline solution is extracted with not only all of humic substances from peat, and organic matter carbohydrates, lignin, waxes, bitumens, which, although they contain some functional groups, but less active or even are inhibitors.

It is found experimentally that in the case of liquid humic fertilizer from sludge - wastes from the production of liquid bio - optimal are 1.5 to 2.0%concentration of caustic potash. This conclusion made in the evaluation of the whole complex of the studied parameters in experimental models of liquid humic fertilizer (potassium humates, humic acids, plant food elements).

It is found experimentally that the optimum volumetric ratio is the sediment: water solution of caustic potassium = 1:10. With the increase of this ratio is a more diluted solution prepared liquid humic fertilizer with a lower quality of performance and additionally increase the cost of the preparation of larger quantities of alkali. Decreasing this ratio is a more concentrated solution prepared liquid humic fertilizer, but the qualitative characteristics of this increase is not proportional, in addition decreases the yield by 7-11%.

It was established experimentally that the effective temperature interval interaction sludge and caustic potash is 55-65°C, while the optimum temperature is 60°C. If the temperature is below 55°C, the extraction of humic substances is much slower, which reduces the quality of liquid humic fertilizer and increases the time required for its production, and at temperatures above 65°C in alkaline hydrolysis of humic substances, as well as the inactivation of some biologically active substances, lizirovania cells representatives microflora.

The total time of sedimentation, resulting in the infusion of the reaction mixture to 6 hours, broken into equal sub-the key of time is optimal and economically justified from the point of view of the allocation of humates and humic acids. Longer infusion increases the length of the production process and increases the cost of technology for production of liquid humic fertilizer, less time is not sufficient to produce a quality product.

The invention is illustrated in the drawings.

The figure shows a diagram explaining the method of producing a liquid humic fertilizer for crop production and agriculture; table 1 characterizing the composition of liquid humic fertilizer; table 2, indicating the influence of liquid humic fertilizer on the growth and development of spring wheat cultivar "Iryna"; table 3 explaining the influence of liquid humic fertilizer on yield of potato varieties "Zhukovsky"; table 4, describing the effect of liquid humic fertilizer on the growth of microorganisms of the soil under potato varieties "Zhukovsky".
