CATDOLL : CATDOLL: How much organic fertilizer can be produced from one ton of cow dung?

1. What kind of fertilizer is cow dung after fermentation?

Cow dung becomes organic fertilizer after fermentation.

2. What are the uses of cow dung?

Dung can be used as base fertilizer. The cow dung used must be rotten and fermented before use. It is recommended to use it as base fertilizer and apply it in the trench. Mix the dry cow dung and the bran, add the fermentation powder, and after 2-3 days of stacking and fermentation, the cow dung will turn from black to yellow and emit an alcohol smell. It can be used to feed pigs. Cow dung can be used to grow mushrooms, produce seedling soil, grow vegetables, and generate electricity.

1. Cow dung can be used as base fertilizer

1. The cow dung used must be rotten and fermented before use. Otherwise, the heat released during fermentation may harm the plants and pathogens may be introduced into the soil.

2. It is recommended to use it as base fertilizer and apply it in the furrow. Cow dung fertilizer releases slowly and has a generally high salt content. It should be used as base fertilizer and it is not recommended to apply it to the soil after applying it in the furrow. When used for surface application, the amount should be controlled and the concentration should not be too high to avoid damage to the plants.

2. Fermented cow dung can be used to feed pigs

1. After mixing the dry cow dung and bran, add the baking powder. The amount of baking powder depends on the temperature. At 25 degrees Celsius, 500 grams of baking powder is used for every 50 kg of cow dung and 50 kg of bran.

2. After 2-3 days of stacking and fermentation, the cow dung turns from black to yellow and emits an alcohol smell, which can be used to feed pigs.

3. Cow dung can be used to grow mushrooms

1. Cow dung is used as raw material for edible fungus cultivation. The high temperature during the fermentation process can kill the grass seeds in the cow dung. The waste mushroom sticks after mushroom production are returned to the fields, which is a rare organic fertilizer.

2. The test demonstration proved that the edible fungi produced from cow dung taste good, the quality is significantly improved, and the successful mushroom rate of mushroom sticks is also significantly improved, reaching more than 98%. Compared with traditional raw materials, the average production cost of wheat bran, soybean meal and corn flour is reduced by about 40%, and the output is increased by more than 50%, with great economic benefits.

4. Cow dung can be used to produce seedling soil

Cow dung production seedling soil comprehensively utilizes animal dung and crop straw to produce cultivation substrates and biological organic fertilizers, reducing environmental pollution.

5. Cow dung can be used to grow vegetables

Villagers use organic vegetable leaves and processed waste as green feed to feed dairy cows, and use cow dung compost for the production of organic vegetables.

6. Cow dung biogas can be used for power generation

Use a forklift to shovel the cow dung into the separator, which separates the sand, firewood and grass. After separation, the dung is put into the manure pool. After soaking for a certain period of time, it is transferred from the manure pool to the adjustment pool. After adjusting to a certain concentration, it is put into the biogas fermentation tank regularly and quantitatively using CNC equipment. The blue one is the biogas fermentation tank, which uses high-temperature fermentation in medium-temperature fermentation. The biogas produced by the fermentation is stored in the white gas storage tank above and transported downward using pipelines to the electrochemical system.

3. How many pounds does one ton of cow dung weigh?

One ton of cow dung weighs about 760 kilograms.

The water content of wet cow dung is 80%. To produce organic fertilizer, other auxiliary materials need to be added. Therefore, the weight of 1 ton of wet cow dung produced through fermentation, water evaporation, crushing and mixing is about 760 kilograms.

If the cow dung is not treated, it will breed a large number of mosquitoes and flies, and also cause the spread of bacteria. Using cow dung to process and produce organic fertilizer is in line with the environmental protection concept of waste utilization. Cow dung is a cold fertilizer, which ferments and matures slowly, and takes longer than other hot raw materials to ferment.

4. How much biogas can be produced from one ton of cow dung?

One kilogram of dry cow dung can produce 0.3 cubic meters of biogas. So, one ton is 300 cubic meters.

Dry cow dung contains 10-20% crude protein, 1-3% crude fat, 20-30% nitrogen-free extract, and 15-30% crude fiber. It has high nutrient content and can become a high-quality organic fertilizer product after fermentation. It can loosen the soil, improve soil compaction, chelate trace elements in the soil, and improve soil fertility.

Biogas is a gas produced by the decomposition and metabolism of organic matter such as straw, weeds, human and animal feces, garbage, sludge, industrial organic wastewater, etc. under anaerobic conditions by a small amount of anaerobic microorganisms.

5. How to use cow dung during famine?

Don't Starve Cow Dung is used to be installed on the Don't Starve version and played for the audience to watch. The cow dung here refers to the software content installed in the Don't Starve version.

6. What is the most effective way to use cow dung?

Cow dung, as the name suggests, is the excrement of cows, that is, feces. In Tibetan, it is called "Jiu Wa", which has many uses, such as fuel. Let's learn about the uses and value of cow dung and how to deal with it to make the most money.

1. What are the uses and value of cow dung?

1. Cow dung can be used as fuel: In Tibet, my country, cow dung has been used as fuel for making tea and cooking for thousands of years. This not only solves the problem of cow dung but also provides people with fuel, which can be said to kill two birds with one stone.

2. Cow dung can be piled up and fermented as fertilizer: Cow dung not only takes up space but also has a bad smell, but if it is piled up and fermented, it can be used as organic fertilizer.

3. Cow dung can be fermented as a substitute for coal and biogas to generate electricity: the electricity generated by fermenting cow dung can save 1.2 million yuan in electricity bills each year. In addition, Fengdu County can also develop cow dung sticks and cow dung honeycomb coal. Cow dung sticks made from cow dung have a high combustion value as fuel. Cow dung honeycomb coal is made by pressing cow dung and coal in a ratio of 4:6, which solves the pollution of honeycomb coal combustion to the atmosphere.

4. Cow dung can be used as animal feed: Cow dung contains various nutrients and minerals, and after processing, it is still very suitable for use as feed.

5. Cow dung can be used as a fungus feed to grow fungi: dehydrated and fermented cow dung can be used with cotton husks, corn cobs, etc. as a fungus feed to cultivate Agaricus bisporus and other fungi. If there is a large demand for Agaricus bisporus in the local area, a small amount can be tried.

6. Cow dung can be used as a raw material for earthworm farming: earthworm powder is a good additive for feed, with a higher protein content than fish meal. The current price of fish meal is more than 20,000 yuan per ton. If earthworm powder is developed on a large scale, the benefits will be considerable. The Beijing Institute of Nutrition Sources has shown that protease preparations, microbial preparations and feed additives made from earthworm powder are natural health care agents for animals. Feeding livestock and poultry with them can significantly promote animal growth and make animals rarely infected with diseases. Various special fertilizers produced with earthworm manure as the main raw material are not only highly efficient, but also can inhibit the spread of diseases and insect pests of crops, while also increasing ground temperature, water retention and fertilizer retention.

7. The image of cow dung can also be used as a toy, because cow dung is homophonic to "Niu Fen", which has a good meaning, so it sells very well as a toy.

2. How to deal with cow dung in the most profitable way?

1. Dry the cow dung and use it as fuel for heating: the heat of cow dung powder is high and the combustion smoke is small, which is basically smokeless, so the cow dung can be collected and dried and sold to farmers for heating kangs or contact some fixed boiler manufacturers.

2. Ferment cow dung to make a biogas digester: Collect cow dung and ferment it into a biogas digester to convert it into electrical energy. In the process of biogas production, pathogenic microorganisms, parasite eggs, etc. in the cow dung can also be killed, which will not cause secondary pollution to the environment. The fermented residue can also be used as fertilizer, killing two birds with one stone.

3. Use cow dung as feed for chickens and fish: The processed cow dung and bran are piled up and fermented, and used to breed earthworms as feed for chickens, fish and other animals. This recycles organic matter, increases profits and does not cause environmental pollution.

4. Use cow dung to grow mushrooms: Mix cow dung with straw for fermentation, and then use it as a substrate to grow mushrooms and other fungi. There are many techniques and methods of learning how to use cow dung to grow mushrooms on the Internet, so as to achieve high-value utilization of cow dung.

5. Process cow dung into organic fertilizer: Cow dung can be processed into organic fertilizer, which is mainly sold to ecological plantations, orchards, flower plantations, etc.

3. How much does cow dung cost per ton?

1. The price of ordinary cow dung without processing and treatment is about 100 yuan/ton. You can ask the local cattle farm for detailed prices.

2. If the cow dung has been dehydrated and deeply processed, it can be sold for 1,000 yuan per ton.

4. How is cow dung processed into fertilizer?

1. First, dry the cow dung in the sun or drain it to control the moisture content of the cow dung below 85%, and then add straw to the cow dung. The ratio of cow dung to straw is 7:3, so that the carbon ratio of the raw material (cow dung) and the auxiliary material (straw) is controlled at 23-28, and the moisture content is controlled at 52%-68%.

2. Add organic fertilizer fermentation and decomposition agent. After the raw materials, auxiliary materials and bacterial agents are mixed and stirred, they can be piled up for fermentation. The requirements for pile up are: the mixed materials are piled up on the fermentation field into a trapezoidal stack with a bottom width of about 1.8-3 meters, a top width of 0.8-1 meters and a height of 1-1.5 meters, and a distance of about 0.5 meters between the stacks. (The above width is only a reference value, the specific value is subject to the actual situation)

3. After the preparation, the temperature will rise to above 60℃ within 24-48 hours. Keep the temperature for 48 hours before turning the pile. Be sure to turn the pile evenly and thoroughly, and try to turn the lower layer of special materials into the middle and upper part of the pile to fully decompose.

4. After the first turning, the pile should be turned once a week. If the temperature exceeds 70℃, the pile must be turned immediately, otherwise the beneficial microorganisms and fermentation bacteria will be killed in large quantities, which is not conducive to fermentation and decomposition.

7. How to ferment cow dung to grow vegetables?

Method and steps of fermenting cow dung to make organic fertilizer:

1. Prepare materials: 2.5 tons of dry cow dung, 1 box of Qi Fu bacterial fertilizer fermentation agent (cow dung fermentation agent - fermented cow dung to make organic fertilizer), about 200 kg of straw powder (grass powder, sawdust, bran, edible fungus matrix, cake meal are all acceptable).

2. Stirring: Mix the cow dung and fermentation agent evenly, check the dryness and humidity of the fermentation material, which should be around 40-50% (i.e., hold the fermentation material tightly with your hand, and feel that there is water on your hand but it does not drip, and it will fall apart if you loosen it). Be sure to mix it well.

3. Building a pile: Pile the mixed materials together. The pile should not be too small, usually 2 meters wide and 1.5 meters high. The length depends on the fermentation volume. This is conducive to internal temperature rise.

4. Fermentation environment: Winter or summer is fine. In winter, fermentation can be done in a greenhouse.

5. The fermentation of cow dung is completed in a very short time: Due to the high bacterial content and strong activity of the Qi Fu bacteria agent, the dung will ferment and heat up quickly, accelerating the decomposition of the dung, which takes 7-12 days (depending on the external temperature).

6. What does cow dung look like after fermentation: After fermentation, cow dung is still cow dung, but it is more decomposed, darker in color, and has no odor.

7. How to make fertilizer from fermented cow dung: If the fermented cow dung is dried and crushed, it can be packed and sold as powdered organic fertilizer. It can also be made into granules by a mixer or granulator, and then packed into bags as granular organic fertilizer.
