Description

Technology area

The invention relates to biotechnology and agriculture and represents the first proposed method for producing liquid compost based on field crop seedlings. The method is simple in execution, does not require large labor costs and complex equipment, allows you to obtain a product characterized by low consumption rates and high efficiency, the absence of unpleasant odor, pathogens and weed seeds, the possibility of long-term storage and multipurpose use in agricultural practice. The compost obtained by this method can be used as a liquid fertilizer, a biomeliorant, a remediant, a plant protection agent against diseases, a ferment for ensiling, a feed additive, a means for composting manure.

State of the art

Compost is a wide range of fertilizers obtained as a result of decomposition of various organic substances under the influence of microorganisms (see - http://www.cnshb.ru/AKDiL/0017/base/RK/007190.shtm) [1]. To date, various methods of composting (composting) are known. For traditional (solid) composts, manure or slurries, feces, bird droppings and other similar materials mixed with peat (straw, sawdust, etc.) are most often used as raw materials (Yagodin et al., 2002) [2] ... The process of preparing solid composts is long, laborious and requires special conditions. Depending on the properties of the compost components and the season, the compostable mass is kept for 1-4 months, then used as the main fertilizer for various crops in the same doses as bedding manure. The disadvantages of traditional composting methods are:

- labor intensity, the need to use bulldozers, loaders, stackers and other complex equipment;

- long duration of the process;

- the use of raw materials that are likely to contain pathogens of animals and humans (manure, slurry, dung, feces, etc.), which requires additional sanitary measures in the production and use of compost;

- unpleasant odor;

- high consumption rates of the resulting product (10-100 t / ha), which determines low economic efficiency.

A method for preparing compost (analogue - RF Patent 2112764) [3] has been proposed, including layer-by-layer stacking of manure and moisture-absorbing organic material, as well as 0.1 part (by weight) of the finished compost, mixing and transfer of the resulting mixture to a fermenter, where the composting process is carried out in within 3-4 days at a mixture humidity of 50-60% and an oxygen concentration in it ranging from 5 to 12%. This method allows to reduce the compost preparation time to several days, but does not eliminate other disadvantages of traditional composts.

The Eco-Farming Company produces liquid compost obtained by fermenting diluted slurry for 2 weeks at room temperature (analogue - see http://eko-navoz.ru/content/kompost.html) [4]. Composting is carried out without access to oxygen, while pathogenic bacteria and nematode eggs die, so the fertilizer is safer from a biological point of view. This method allows you to significantly reduce the cooking time compared to solid composts, however, the disadvantages of the resulting product are:

- the likelihood of residual pathogens;

- unpleasant odor;

- high consumption rates (15-30 t / ha);

- low manufacturability of application (it is recommended to water the plants a few hours before applying liquid compost; it is necessary to apply compost not directly under the root, but in special grooves made around each plant or in the aisle; after the liquid is absorbed, these grooves are leveled with soil; fertilize plants need compost in small portions - all this is difficult to implement in the conditions of farming practice);

- the possibility of using the product only as fertilizer (plant nutrition).

An automated installation and a method for its use for the preparation of liquid compost (analogue - Patent US 20100236308) [5] are proposed. The plant is a rotating carousel machine with a protective screen, into which the loader feeds organic matter along a conveyor, as well as a system for collecting and filtering liquid and an unloading device for removing waste organic material from the carousel. The system allows producing liquid compost in a short time (hours), but it is difficult to operate, requires high energy consumption and does not solve the problems of sanitation (presence of pathogens). The resulting liquid compost also requires high consumption rates and cannot be stored, which is a significant disadvantage of the product. Also, as a result of the process, organic waste accumulates that has not passed into the liquid phase, which must be disposed of separately.

There is an effective way to obtain liquid compost from fresh aboveground plant biomass without using expensive equipment (prototype - Potapov I., 2015; Zhuravsky N.I., 1990; Tumanov A., 2011) [6, 7, 8]. The essence of the method is as follows: a suitable plastic or metal container is half filled with freshly cut grass, filled with water to the top. You can also add urea to the container at the rate of 50 g / 10 l. The barrel is covered with a lid and v left for 1-2 weeks until tender. Next, the grass is removed and disposed of, and the resulting liquid compost is used for fertilizing (watering the plants). With this method, liquid compost can be obtained in a short time with practically no labor and energy costs, however, the prototype also has a number of disadvantages, namely:

- the resulting product is an ineffective fertilizer requiring high consumption rates (0.1 l more per 1 m ² , which corresponds to over 1000 l / ha);

- the compost practically cannot be stored;

- the probability of the residual content of weed seeds and pathogens;

- unpleasant odor;

- the presence of waste in the form of semi-decomposed grass;

- the possibility of using the product only as fertilizer (plant nutrition).

Disclosure of invention

The technical result of the invention is a method for simple and quick waste-free production of liquid compost (hereinafter referred to as "Albit-BR"), characterized by low consumption rates and high efficiency, lack of unpleasant odor, pathogens and weed seeds, the possibility of long-term storage and multipurpose use in agriculture. The method allows to overcome the existing disadvantages of analogs and to obtain a qualitatively higher result in comparison with the prototype.

The task is achieved by improving the prototype. Instead of cut grass (as in the prototype), crushed seedlings of field crops are used for composting. Unlike the prototype, composting is carried out using the drug Albit, TPN and consists of 3 stages: obtaining and grinding seedlings, aerobic stage, anaerobic stage. The drug Albit, TPB based on poly-beta-hydroxybutyric acid from soil bacteria has been widely used in agricultural practice for many years to increase plant productivity and fight pathogens (Zlotnikov A.K. et al., 2009) [9]. The drug is distinguished by high environmental friendliness and harmlessness. It is known that Albit is able to stimulate the development of beneficial microorganisms in the soil (Zlotnikov A.K. et al., 2014) [10], and this invention is the first to propose the use of the drug in composting. Seedlings of agricultural crops contain a sufficient number of endophytic saprophytic microorganisms. In the proposed method of composting, the preparation Albit, TPN stimulates the growth of seedlings and the development of natural beneficial seedling microflora, suppressing pathogenic and putrefactive microorganisms.

As a result of our own experiments, it was found that the use of these new approaches provides the emergence of qualitatively new valuable features: waste-free process, low consumption rates of the resulting product, absence of pathogens, weed seeds and unpleasant odor in the final product, its high efficiency, the possibility of long-term storage and multi-purpose use in agricultural practice: as a liquid fertilizer (feeding) of plants, an ameliorant, a remediant, to protect plants from diseases, as a leaven for ensiling, a feed additive, a means for composting manure. At the same time, the positive properties of the prototype are preserved (speed and simplicity of composting, no need for complex equipment). Thus, the new method of obtaining compost "Albit-BR" meets the criterion of "inventive step".

The method includes the following steps:

1. Getting and grinding seedlings.

They take seeds of barley or other field crops (oats, wheat, triticale, rye, millet, rice, sorghum, corn, soybeans, buckwheat, etc.) free from debris and other impurities, and place them in vessels for germination and poured with an aqueous solution of the preparation Albit, TPS so that all the seeds were completely immersed in the solution. Any barrels, basins, pots, fermenters, breeding boxes and other containers can be used as vessels. The concentration of Albit in the solution should be in the range from 0.001% to 10%. As it was found in our experiments, the concentration of Albit less than 0.001% does not have the proper stimulating effect on seedlings and beneficial microflora, over 10% - the effect of the drug decreases due to the high concentration. The seeds are left in solution until germination (the appearance of roots, coleoptile or cotyledonous leaves). This process takes several days. As a result, the entire solution is absorbed by the seeds; get an accreted mass of swollen seedlings, which is then crushed until smooth. Grinding can be performed on millstones, meat grinders, mills, or other dispersing devices. The resulting crushed mass is diluted with water in a ratio of 1: 3 to 1:90.

Composting of seedling material actually begins already in the process of grinding them, due to the active development of endophytic microbiota under the influence of Albit.

2. Aerobic composting.

The liquid mixture obtained in the previous stage is poured into plastic or metal containers and left for at least a day in the presence of oxygen. We found that the composting of seedling material by the proposed method does not include a noticeable development of thermophilic microorganisms; composting is carried out at a temperature close to room temperature (from + 10 ° C to + 40 ° C). This can be explained by the fact that the seedling material is rich in endophytic lactic acid bacteria (Salminen S. et al., 2004) [11].

3. Anaerobic composting.

At the last stage, the containers with the compostable mixture are tightly closed with lids and kept at temperatures from + 10 ° C to + 40 ° C. At the same time, during the composting process, the acidity of the product increases, the pH decreases. Composting is carried out until the final acidity of the product is reached in the pH range from 3.2 to 4.2, after which the compost becomes ready for use. This stage lasts approximately 8-12 days.

In the production of compost "Albit-BR" the seedling material is used completely, no waste is generated, composting is carried out due to the natural endophytic microbiota of seedlings, which suppresses the development of pathogenic microorganisms. In the process of composting and storing compost, there is no noticeable emission of gases, there is no unpleasant smell.

The resulting compost "Albit-BR" can be stored for at least 2 months at room temperature without changing its useful properties, which distinguishes it from the prototype.

Signs that distinguish the proposed method from the prototype and analogues are not identified in other technical solutions, which allows us to conclude that it meets the criterion of "significant differences". Methods for producing composts based on seedlings of agricultural crops using the drug Albit, TPN have not yet been developed in world science and practice and there is no information about them in scientific, technical, patent and other literature, which proves the novelty of the present invention.

The implementation of the invention is illustrated by the following examples:

Example 1.

Take 1 kg of seeds of spring barley variety Vizit. Make sure the seeds are free of infection, debris, weed seeds and other impurities. Seeds are placed in a 20 l plastic can, filled with 5% solution of Albit, TPS so that the seeds are completely immersed in Albit solution (seed layer is about a centimeter below the solution level). The seeds and solution are mixed. The seeds are left in an open vessel in solution at room temperature until germination. On the 3rd day, the appearance of roots is first noted, then a coleoptile - which means the transformation of seeds into seedlings. At this point, the Albit solution is completely absorbed by the seedlings. The resulting mass of sprouts accreted by the roots with the help of a meat grinder is crushed to a uniform state, 1.1 l of the crushed mass is obtained. The resulting mass is diluted with clean tap water in a ratio of 1 part of the crushed mass to 10 parts of water and mixed. Next, the liquid mixture obtained in the previous stage (total volume 11 l) is poured into the original container in which the seeds germinated, and left for 24 hours at room temperature under oxygen access (aerobic composting). Then the container with the compostable mixture is tightly closed with a lid with a rubber ring, stopping the access of air (anaerobic composting). It is kept at room temperature, a sample is taken every 2 days to measure the pH. It is noted that the pH value decreases from 6.7 to 4.2 by the 8th day of anaerobic composting. After several sampling, it is ensured that the pH of the product does not drop anymore and is constantly in the range from 3.2 to 4.2, which serves as a signal that the compost is ready.

The liquid compost "Albit-BR" prepared in this way has a faint pleasant sour-milk smell, a light fawn color. The content of lead is less than 0.05 mg / kg, cadmium - less than 0.001 mg / kg, mercury - less than 0.0025 mg / kg, arsenic - less than 0.05 mg / kg. Sanitary-indicative bacteria Escherichia coli, as well as pathogenic bacteria of the genera Salmonella, Proteus, Clostridium are absent. Pathogens, helminth eggs and weed seeds are absent.

Example 2.

The compost obtained according to Example 1 is stored for 2 months at a temperature of + 25 ° C in a tightly closed plastic canister. Retention of the pH in the range from 3.2 to 4.2 is noted, as well as compliance with the quality indicators specified in Example 1. A conclusion is made about the shelf life of the product at least 2 months.

Example 3.

Compare the effectiveness of the compost "Albit-BR", prepared in Example 1, and the prototype, prepared by the method specified in (6). Field experience is laid in LLC "Kalinina" (Dyurtyulinsky district, Republic of Bashkortostan). The experiment is carried out on crops of spring wheat of the Vatan variety. Soil - typical black soil, tillage - autumn autumn plowing followed by disking, buckwheat predecessor. The area of each experimental plot is 0.5 hectares, 3 replicates. The composts are brought with water to a working solution volume of 1000 l / ha and applied to the soil by watering immediately before sowing. After harvesting wheat in August, the biological yield of each of the options is taken into account (the results are presented in Table 1).

It can be seen that "Albit-BR" has a significant positive effect on wheat yield when using a consumption rate of 1 l / ha as a liquid fertilizer. To achieve the yield effect comparable to that of Albit-BR, the prototype requires 1000 times more dosage. The conclusion is made about a much higher efficiency of the compost "Albit-BR" in comparison with the prototype.

It is also noted that when stored for 2 months, the effectiveness of "Albit-BR" does not decrease.

Example 4.

"Albit-BR" is prepared as in Example 1, but the concentration of the drug Albit, TPN in the solution used for soaking the seeds is varied. Compost prepared using solutions of different concentrations is tested in a field experiment as described in Example 3. All compost samples are noted to maintain pH in the range from 3.2 to 4.2, as well as conformity to the quality indicators specified in Example 1. All In experimental plots, "Albit-BR" is introduced into the soil as a liquid fertilizer at a dosage of 1 l / ha. The results are presented in Table 2.

The results of the experiment show that significant positive differences with the control are achieved in the range of concentrations of Albit, TPS from 0.001% to 10%.

Example 5.

"Albit-BR" is prepared as in Example 1, but the degree of dilution of the mass of seedlings with water at the end of the first stage of composting is varied. In addition, instead of plastic cans, galvanized metal drums with tight-fitting lids, with a volume of 100 liters, are used. Compost prepared using different amounts of water is tested in a field experiment as described in Example 3. All compost samples are noted to maintain a pH in the range from 3.2 to 4.2, as well as comply with the quality indicators specified in Example 1. All In experimental plots, "Albit-BR" is introduced into the soil as a liquid fertilizer at a dosage of 1 l / ha. The results are presented in Table 3.

The results of the experiment show that significant positive differences with the control are achieved in the interval of seedling dilutions with water from 1: 3 to 1:90.

Example 6.

"Albit-BR" is prepared as in Example 1, but the temperature at which the 2nd and 3rd stages of composting are carried out (aerobic and anaerobic composting) is varied. In addition, similar stainless steel containers are used instead of plastic cans. Compost prepared at different temperatures is tested in a field experiment. In all compost samples, the maintenance of the pH in the range from 3.2 to 4.2 was noted, as well as compliance with the quality indicators specified in Example 1.

The plotting experiment is carried out on the experimental field of the All-Russian Research Institute of Plant Protection of the Ministry of Agriculture of the Russian Federation (Ramon, Voronezh Region) on soybean plants of the Radiant variety. The size of the plots is 15 m ² , the location is randomized, the replication is 4 times. Planting date - May 5, seeding rate - 400 thousand seeds per hectare. The soil is leached, medium loamy chernozem, humus content 4.6%, pH 6.1. The predecessor is Sudanese grass. Tillage - autumn plowing to a depth of 25-27 cm, early spring harrowing and pre-sowing cultivation. Fertilizers and pesticides are not applied. During the growing season, 3 manual weeding is carried out. Manual harvesting from the entire area of the plots, followed by threshing and determination of the mass of seeds (biological yield). On all experimental plots, "Albit-BR" is introduced into the soil in a dosage of 1 l / ha as a liquid fertilizer simultaneously with pre-sowing cultivation. The results are presented in Table 4.

The results of the experiment show that significant positive differences with the control are achieved when composting is carried out in the temperature range from + 10 ° C to + 40 ° C.

Example 7.

The compost "Albit-BR" is prepared as in Example 1, but a representative sample of seeds of various field crops is used for preparation. Prepare one version of compost based on seeds of barley, oats, wheat, triticale, rye, millet, rice, sorghum, corn, soybeans, buckwheat of different varieties (as indicated in Table 5). In addition, 20 l stainless steel fermenters are used instead of plastic cans. The measurement of the pH electrode and the supply / shutdown of the air supply are carried out through the ports of the fermenters. Grinding the seedlings is carried out using the stirrer blades of the fermenters. The duration of the first stage of the process differs from that described in Example 1, and is, depending on the type of plant, from 2 to 7 days. Also, depending on the culture, reaching the final pH in the range from 3.2 to 4.2 in the third stage takes from 8 to 12 days.

In all variants of the compost "Albit-BR", the maintenance of pH in the range from 3.2 to 4.2 is noted, as well as compliance with the quality indicators specified in Example 1. The obtained different varieties of compost "Albit-BR" are tested in a field experiment as liquid fertilizers.

Plotting experiment on the experimental field of the All-Russian Research Institute of Plant Protection of the Ministry of Agriculture of the Russian Federation (Ramon, Voronezh region) is carried out on spring barley of the Odessa 100 variety. The soil is medium loamy, medium humus, medium thick chernozem with a humus content of 5-6%, pH is 5-5.5 %, hydrolytic acidity - 5.1-7.5 meq / 100 g of soil. The predecessor is annual grasses for green forage. Soil cultivation included post-harvest stubble plowing, autumn plowing to a depth of 24-25 cm, pre-sowing cultivation by 6-8 cm. Various versions of Albit-BR compost are brought with water to a working solution volume of 1000 l / ha and applied to the soil by watering a day before sowing. Seeds are sown on April 20, the seeding rate is 2.5 c / ha. The size of the plots was 10 m ² , the placement was randomized, the repetition was 4 times. Harvesting and accounting for the biological yield of barley - in the phase of full ripeness. The results are presented in Table 5.

According to the results of the experiment, it is concluded that the effectiveness of the varieties of compost "Albit-BR" prepared using seeds of spring barley of the Vizit variety (as in Example 1) and different types and varieties of other field crops does not differ statistically significantly.

Example 8.

To demonstrate the possibility of using compost "Albit-BR" as a biological ameliorant, compost is prepared according to Example 1. Field experiment is laid in LLC "Tesnitskoye" (Aleksinsky district, Tula region). Culture - white mustard, test and control fields of 5 hectares. The soil is gray forest, medium loamy. The predecessor is winter wheat.

"Albit-BR" is applied to the soil once in spring (04/27/2019) before sowing. After applying fertilizers and soil herbicide to the soil on the same day with a self-propelled sprayer - spraying the soil with a working solution of compost (working solution consumption - 200 l / ha). After that, disking is carried out (with a disc harrow with rollers) to embed the compost into the soil to a depth of 6 cm.

On the control field, a mustard yield of 10.5 c / ha is obtained, on the experimental field -12.75 c / ha (an increase in yield of 2.25 c / ha, or 21.4%). After harvesting, the agrochemical parameters of the arable soil horizon are determined. In the experimental field, an excess of the content of nutrient forms available to plants over the control is revealed: K - by 12.2%, Cu - by 6.4%, Mn - by 11.4%, Mo - by 14.3%, nitrate nitrogen - by 58.8%. Despite the removal of nitrogen with an increased yield, the total nitrogen content in the arable horizon of the soil increases by 100 mg / kg (+ 6.7% to the control). Mycological analysis reveals a 67% decrease in the number of pathogenic fungi of the genus Fusarium in the soil of the experimental field.

These facts are explained by an increase in the activity of the natural beneficial microflora of the soil (including nitrogen-fixing) and testifies to the action of the compost "Albit-BR" as an effective ameliorant.

Example 9.

To demonstrate the possibility of using compost "Albit-BR" as a biological ameliorant, compost is prepared according to Example 7 on the basis of seeds of spring wheat variety Voronezhskaya-10. Field experience is laid in the All-Russian Scientific Research Institute of Organic Fertilizers - a branch of the FGBNU "Verkhnevolzhsky FANTS" (Vyatkino, Vladimir region).

Culture - spring barley Sudar, plotting experiment, plot area 50 m ² , 4-fold repetition. Albit-BR is introduced into the soil in two doses: 0.1 l / ha and 1 l / ha before sowing. The barley yield in the control was 22.8 c / ha, in the experiment at a dose of "Albit-BR" 0.1 l / ha - 27 c / ha (an increase to the control 4.2 c / ha or 18%), at a dose of " Albita-BR "1 l / ha - 27.4 c / ha (an increase of 4.6 c / ha or 20% to the control). In all experimental variants, in the tillering phase of barley plants, an increase in the content of available nitrogen in the soil is observed (up to values of 9.5-16.1 mg / kg versus 3.6 mg / kg in the control soil), which characterizes Albit-BR as a biomeliorant capable of providing an increase in soil fertility.

Example 10.

To demonstrate the possibility of using compost "Albit-BR" as a soil remediation agent, compost is prepared according to Example 1. They are introduced into the soil of an oil-contaminated site at the Sormovskaya oil depot ("LukoilNizhegorodnefteprodukt", Nizhny Novgorod). The site is a soil on which containers for waste oil oils are placed. From time to time, spills of oil products were covered with sand. The soil throughout the territory is saturated with oils. The load of oil products at the site before the start of work was high (average concentration in the area is 11.9%). Albit-BR is applied at a dosage of 15 l / ha before sowing oil-tolerant grasses as one of the stages of complex reclamation. By the end of the season, a decrease in the load of oil products under the influence of composting by 4.8% is noted.

Example 11.

To demonstrate the possibility of using compost "Albit-BR" as a means of protecting plants from diseases, a field experiment is laid according to Example 7. In the phase of complete tillering of barley, the development of root rot is taken into account. The results are presented in Table 6.

Based on the results of the experiment, it is concluded that the biological efficiency of all varieties of compost "Albit-BR" is about 50%, which is an acceptable value, since the effectiveness of most of the currently recommended chemical remedies against root rot is 40-70% (Tyuterev, 2005) [12].

Example 12.

To demonstrate the possibility of using compost "Albit-BR" as a starter for silage, the compost is prepared according to Example 1. The experiment is laid in LLC "Rus" in the Stavropol Territory. Alfalfa is mown at the beginning of budding. The mass intended for silage is pre-crushed. 1 liter of compost "Albit-BR" is diluted in 150 liters of water and the resulting working solution is applied to 50 tons of silage using standard metering pumps. Spraying with the working solution is carried out after the green mass is evenly distributed over the trench in layers about 50 cm thick. The trench is laid and covered within 5 days. After filling and tamping the trench, the silage mass is covered with plastic wrap on top and pressed on top with earth and old car tires. After 80 days, high-quality silage is obtained with a dry matter content of 370 g / kg, lactic acid 2.5%, acetic acid about 1%, butyric acid less than 0.2%.

Example 13.

To demonstrate the possibility of using compost "Albit-BR" as a feed additive, compost is prepared according to Example 1. The experiment is laid in the Sosnovoborsky agricultural enterprise in the Vladimir region on black-and-white calves aged 10 days. The size of the control and experimental groups is 12 animals. For 20 days, the calves of the experimental group are fed with swill the compost "Albit-BR" at a dosage of 50 ml / head / day. The weight gain in the control group averages 320 g / head / day, when using compost - 405 g / head / day. In the experimental group, the absence of intestinal disorders in calves was noted.

Example 14.

To demonstrate the possibility of using compost "Albit-BR" as a means for composting manure, "Albit-BR" is prepared according to Example 1. The experiment is laid in CJSC "Suvorovskoe" of the Vladimir region in the warm season (at an air temperature of at least 10 ° C). Manure from the cattle farm is placed in piles with a height of 1-2 m, during the laying process it is watered layer by layer with liquid compost "Albit-BR". Consumption rate - 1 liter of compost per 10 m ^{3 of} manure. After 5 and 15 days, the piles are turned over. After 50 days, a decrease in the volume and toxicity of manure, a sharp decrease in the number of pathogenic microorganisms, and the disappearance of an unpleasant odor are noted.
