Description

The invention relates to agriculture, in particular to fertilizers that contribute to the restoration of humus in the arable layer and increase the productivity of crops.

Known fertilizer for the soil, which is based on the use of jellyfish as fertilizer for the soil (see SU, copyright certificate No. 986907, M. cl ^3. C 05 F 1/00. Fertilizer for the soil / E.V. Makarov, V.V. Guskov, I.E. Yelsukov and V.P. Razmazin (USSR) .- Application No. 3278802 / 30-15; Announced 05/19/1981; Publish. 07.01.1983. Bull. No. 1 // Discovery. Inventions. - 1983 . - No. 1).

The vast region of the Lower Volga region is located at a considerable distance from the waters of the Caspian, Azov and Black Seas. The costs of extracting and processing jellyfish do not pay off by increasing the productivity of cultivated crops.

Known nitrogen-containing fertilizer obtained by using the spent liquor for the production of chalky methacrylic acid ester - acrylate waste as nitrogen-containing fertilizer (see SU, copyright certificate No. 800173, Mcl ^3. C 05 F 3/00. Nitrogen-containing fertilizer / V.D. Golubev, I.P. Glebov, ND Kalinichenko and K.A. Lobashov (USSR) - Application No. 2724706 / 23-26; Declared 02.02.1979; Publish. 01.30.1981. Bull. No. 4 // Discovery Inventions. - 1981. - No. 4).

The disadvantages of this fertilizer, obtained on the basis of chemical industry waste, despite the significant content of up to 20-40% ammonium sulfate, are the liquid form (from 43 to 72% water). This is associated with high transport costs and the requirement for special storage containers.

Organomineral fertilizer is known, including nitrogen, phosphoric, potassium salts and hydrolytic lignin, in which, in order to increase the resistance of mineral elements of plants to leaching, it additionally contains peat, and as a nitrogen salt contains urea, as phosphoric salt - double superphosphate, and as potassium salt - potassium chloride, while the components are taken in the following ratio, including dry matter, wt.%:

Urea 15-20 Dual superphosphate 20-30 Potassium chloride 15-20 Hydrolysis lignin 20-40 Peat 10-20

(see SU, copyright certificate No. 952831, M.cl ^3. C 05 F 11/02. Organomineral fertilizer / G.P. Viryasov, M.N. Loyko, G.V. Naumova and A.V. Tishkovich (USSR ). - Application No. 2926613 / 30-15; Announced 05/20/1980; Publish. 08/23/1982. Bull. No. 31 // Discoveries. Inventions. - 1982 - No. 31).

The disadvantage of this fertilizer, despite its long shelf life, is the lack of necessary microelements in it for the growth of all types of plants.

It is also known organic fertilizer used as a nutrient medium in hydroponics, including mineral compounds and water extract of biofuel, in which, in order to increase crop yields, reduce their cost and economical consumption of fertilizer, it contains 20-30% aqueous extract of biofuel , and as a mineral compound contains nitrophosphate, copper sulfate and boric acid in the following ratio of components, wt.%:

Nitrophoska 16.3-19.5 Sulfur Copper 0.02-0.03 Boric acid 0.5-0.7 20-30% water biofreshing infusion Rest

(see SU, copyright certificate No. 996406, M.cl ^3. C 05 D 9/02. Organomineral fertilizer / V.I. Valkov, V.N. Zubkov, G.M. Makarova and A.A. Fridger (USSR ). - Application No. 3272119 / 23-26; Stated 04/02/1981; Publish. 02.15.1983. Bull. No. 6 // Discovery. Inventions. - 1983 - No. 6).

The disadvantages of this organic fertilizer include a limited scope - only when cultivating forage crops.

Organic fertilizer is known, including fermentation products, in which, in order to expand the range of organic biologically active fertilizers that stimulate plant growth and are completely processed by microorganisms, it contains microbial biomass obtained from carbon-containing raw materials as fermentation products; in order to increase its nutritional value and depressive properties against soil moisture evaporation, it contains N-paraffins in an amount of 5 to 12 wt.% (see SU, copyright certificate No. 539018, M.cl ² C 05 F 5/00. Organic fertilizer / A.P. Popov, N.K. Nadirov and Z. D. Sadyrmekov (USSR) - Application No. 1975786/15; Declared 12/14/1973; Publish. 12/15/1976. Bull. No. 46 // Discoveries. Inventions . - 1976 - No. 46).

Despite the fact that a number of oil refineries and gas condensate plants operate in the Lower Volga region, starting from the city of Saratov and ending with the city of Astrakhan, the production of microbial biomass as a fermentation product is not a problem in itself. However, large air costs (up to 80 m ³ per 1 m ^{3 of} nutrient medium) require large and material installations. This fertilizer even has traces of trace elements: manganese, copper, nickel, strontium, chromium, iron, zinc, cobalt, boron. The high cost of fertilizer production according to the described recipe practically negates the savings from increasing crop yields.

The closest object to the claimed invention in terms of features includes complex fertilizer and a method for its production, including dried manure, nitrogen, phosphorus and potassium, in which, in order to increase the efficiency of restoration of soil fertility, it additionally contains trace elements in the following quantitative ratio of components, weight. %:

Dried manure 80-90 Nitrogen 1,5-7,5 Phosphorus 1-5 Potassium 1.5-1.0 Trace elements Rest

A method for producing complex fertilizer, including the processing of manure and the introduction of mineral fertilizers, in which, in order to simplify the processing and storage of manure, the slurry is treated with air in a turbulent stream containing 1: 10-15 air by volume to the slurry, followed by the addition of gypsum in an amount 1.5-6 weight. % (of the total weight of the slurry), drying the resulting mass in a fluidized bed at 300-500 ° C, the introduction of mineral fertilizers and trace elements (see SU, copyright certificate No. 588218, M.cl ^2. C 05 F 3/00. Complex fertilizer and method for its preparation / G. G. Dzhanaev and V. V. Khubaev (USSR) - Application No. 2176670 / 30-26; Declared September 29, 1975; Publish. January 15, 1978. Bull. No. 2 // Discoveries. Inventions. - 1978 - No. 2).

We have taken this fertilizer and its production method as the closest analogues.

The disadvantages of this fertilizer include the high cost of 1 ton of fertilizers and the low digestibility of nutrients and trace elements by plant roots.

The invention consists in the following.

The problem to which the claimed invention is directed is to create cheap complex fertilizers saturated with microelements based on natural resources and decomposition products of organics and animal droppings.

The technical result is an increase in crop yields and preservation of soil fertility.

The specified technical result is achieved by the fact that in the well-known complex fertilizer, including dried manure, mineral fertilizers and trace elements, according to the invention, manure is presented in the form of a meal for processing roots and rhizomes of licorice into a thick extract and products of four-year decomposition of pig droppings in an amount of 15-20 wt. %, bird droppings of four-year decomposition of 15-20 wt.%, cattle of two-year decomposition of 50-55 wt.%, and as micronutrients - a brine of natural sulfate-type bischofite material of the formula M gCl ₂ · 6H ₂ O with a density of 1.20 - 1.35 t / m ³ - the rest.

The described complex fertilizer is obtained by processing the licorice meal of manure and the introduction of mineral fertilizers and trace elements. According to the invention, the decomposition products of the litter of pigs, poultry and cattle 2-4 years old are crushed and separated into fractions with a size of 2-5 mm, meal is added and mixed in the indicated proportions and mixed with bischofite brine by finely dispersed drops into components in fractions manure, then the mixture is dried to a moisture content of 16-22%. Fertilizers are packaged in small packaging for summer residents and sent in bulk to large agricultural enterprises.

Due to the fact that the complex fertilizer contains the main trace elements and in an assimilable form nitrogen, potassium, phosphorus, the above technical result is achieved.

An analysis of the methods for preparing complex fertilizers and the content of nutrients carried out by the applicants and authors, including a search by patent and scientific and technical sources of information and identification of sources containing information about analogues of the claimed invention, made it possible to establish that the applicants did not find an analogue characterized by features identical to all the essential features of the claimed invention.

Therefore, the claimed invention meets the requirement of "novelty" under the current law.

To verify the compliance of the claimed invention with the requirement of "inventive step", the applicants conducted an additional patent search of known solutions in order to identify features that match the distinctive features of the claimed invention from the closest analogue, the results of which show that the claimed invention does not explicitly follow from the prior art and technologies (methods) defined by the applicants, the influence of the claimed essential features of the claimed eteniya transformations to achieve a technical result.

Therefore, the claimed invention meets the requirement of "inventive step" under applicable law.

The soil cover of the Volgograd region over the past ten years, according to scientific institutions of agricultural profile, has been steadily deteriorating. Most of the territories of our region are subject to water, wind and solar erosion. There are many solonetzic and solonetzic soils with a low humus content in the arable (root-inhabited) layer. Along with the low productivity of arable land, desertification, soil degradation due to water and wind erosion, salinization, and soil fertility, especially degumification, are also characteristic. These and other negative phenomena can be minimized by the introduction of complex fertilizers based on organics, waste from the processing of licorice roots and a mineral component, in particular bischofite with a high content of macro- and microelements in an assimilable form for plants. Table 1 presents information on the required amount of organic fertilizers for expanded reproduction of soil fertility on the lands of the Volgograd region of the Russian Federation.

In order to increase the efficiency of restoration of soil fertility and simplify the processing and storage of manure, the disposal of waste processing roots and rhizomes of licorice, the proposed complex fertilizer additionally contains trace elements in the following quantitative ratio of components, wt.%:

Sludge-shaped products of four-year decomposition of pig litter 15-20 Litter of birds of three-four-year decomposition 15-20 Litter and litter of organic origin of cattle of two-year decomposition 50-55 trace elements - brine of the natural mineral bischofite sulfate type of the formula MgCl ₂ · 6H ₂ O with a density of 1.20-1.35 t / m ³ Rest

To achieve a technical result - increasing crop yields and preserving soil fertility - the components of complex fertilizers are subjected to mechanical underworking and microelements are introduced. The decomposition products of two to four years ago from the litter of pigs, poultry and cattle are first crushed, for example, with an IBK-5 feed chopper, then they are separated into fractions of 5 mm on a sieve mill or vibrating table. The fertilizer components in the given quantitative (mass) ratios [(15-20) + (15-20) + (50-55)] are added as a binder, licorice root meal and mixed, and then sent from the batchers to a conveyor belt. Bischofite in the amount of 5-20 wt.% Is applied to the surface of the granules in the form of dispersed droplets with the size of finely dispersed sprayers on nipples using a rod sprayer. Thin spray of bischofite when applied under pressure of 0.05-0.08 MPa ensures even distribution of bischofite brine on the components of complex fertilizer. To increase the shelf life of the fertilizer and reduce its weight during long-distance transportation, the resulting mixture is dried to a moisture content of 16-22%.

Bischofite, a natural mineral in the form of colorless salt, either white or pink, is used as a source of trace elements. The bischofite brine tastes hot and bitter. The mineral is hygroscopic. In air, a mineral, absorbing water molecules, quickly melts, passing into a solution (brine).

On the territory of the Volgograd region, bischofite mineral deposits form a unique cluster. The basis of this mineral is hexahydrate magnesium chloride - bischofite of the formula MgCl ₂ · 6H ₂ O - approximately 87-99%. The composition of impurities includes, wt.%: KCl · MgCl ₂ · 6H ₂ O - 0.10-6.50; MgSO ₄ · 4H ₂ O - 0.10-2.50; Mg · Br ₂ 0.45-0.95; CaSO ₄ - 0.10-0.70; NaCl - 0.10-0.40.

Bischofite brine contains trace elements vital for plants: B - 0.002 - 0.8; Ca - 0.003 - 0.005; Bi - 0.0005 - 0.001; Mg - 0.0005 - 0.001; Fe - 0.003 - 0.03; Al - 0.001 - 0.02; Ti - 0.005 - 0.001; Cu - 0.0001 - 0.003; Si - 0.02-0.20; Ba - 0.0001 - 0.0006; Sr - 0.0001 - 0.02; Rb - 0.0001 - 0.001; Cs - 0.0001 - 0.001; Li - 0.0001 - 0.0003.

Bischofite is mined from wells by the method of underground dissolution, and chlorine-magnesium brine with a concentration of magnesium chloride of 420-430 g / l is pumped out to the surface. Together with the bischofite mineral, all impurities in the form of salts of macro- and microelements completely pass into the aqueous brine. If you evaporate water from brine, you get the original natural salt. The resources of the natural bischofite mineral in the Lower Volga region are estimated in billions of tons. According to a prognostic estimate, bischofite reserves amount to over 200 billion tons and are an inexhaustible base for the production of magnesium and bromine. Mining technology worked out. Extraction of the mineral is carried out through the wells by leaching from the depths of 1500-1700 m. The thickness of the productive layers is 30-50 m.

Bischofite (technical magnesium chloride Magnesium chlode technical - bishofit) with a molecular weight of 203.303, mined in the fields of the Volgograd region, meets the requirements of GOST 7759-73.

Hygroscopic mineral bishofit (bishofit) with the formula MgCl ₂ · 6H ₂ O mined by underground dissolution in the Volgograd region for more than 40 years. Brine is pumped to the surface of the earth - a brine of magnesium chloride with a concentration of 420-430 g / l. The composition of the brine includes all salts contained in the pane, macro- and microelements in an accessible form for plants of cultivated crops. This proves its high efficiency for fertilizing plants and obtaining complex fertilizers when introduced into organics.

The composition of the samples of bischofite leach brine mined in the fields of the Volgograd region is presented in salt form in table 2. A quantitative and elementwise analysis of samples of bischofite brines mined in the Narimanov and Gorodishchensk deposits of the Volgograd region is shown in table 3. Analysis of the samples of bischofite leach brines and their contents in macro and microelements (Volgograd region) are given in Table 4. The content of macro- and micronutrients in the bischofite brine extracted from wells in the city of Volgograd is shown in Table 5 for comparison with the above results and known data from the scientific, technical and reference literature. Wells within the city of Volgograd function non-stop in order to prevent clogging of the channel with salts. In the Volgograd and Astrakhan regions, the Republic of Kalmykia, hundreds of thousands of tons of licorice meal accumulated after processing into thick and dry extracts. The fibrous material of licorice meal is a good binder for the production of granular organic fertilizers.

The claimed complex fertilizer is applied to the soil as well, for example, granular superphosphate. This contributes to the fact that the fibers of licorice root meal are a binder. With a single spreader of mineral fertilizers RMG-4, this fertilizer is dispersed into a strip with a width of 6-12 m with continuous movement of the unit. When applying fertilizer locally, ATT-2 or ATD-2 fertilizer machines are used in the KRN-8.4 set, or SUPN-8 seeders or KRN-8.4 cultivators.

Agrochemical quality indicators of the declared complex fertilizer are presented in table 6. The gross content of standardized materials in the organo-mineral fertilizer produced by the claimed method is shown in table 7. The introduced nutrients with the organic part of the components of the complex fertilizer are shown in table 8, and in terms of dry the substance is in table 9. The chemical analysis of the samples of complex fertilizers is presented by the data in table 10.

The effectiveness of the use of complex fertilizers is shown in tables 11 and 12. The test results on hybrids and hybrid corn compositions cultivated in irrigated agriculture of the Volgograd region show a convincing increase in corn grain as a mid-early group (FAO 200 ... 300), and early ripening group ( FAO 100 ... 150).

Thus, the above information indicates the implementation, when implementing significant distinguishing features of the claimed invention, the following set of conditions:

- a method for producing complex fertilizers, embodying part of the claimed invention, when it is implemented, is intended for use in agriculture and, in particular, in irrigated and non-irrigated agriculture in the cultivation of crops;
