Summary of super simple ways to compost cow manure to fertilize plants quickly

1. Benefits of composted cow manure in farming

Cow manure is a popular organic fertilizer and is very effective in providing nutrients to plants. Using cow manure in farming has many benefits as follows:

• Provide diverse and balanced nutrition for plants:Cow manure is rich in nutrients such as nitrogen (N), phosphorus (P), potassium (K), magnesium (Mg), calcium (Ca) and other trace elements necessary for plant growth. This ensures that plants are infused with enough diverse nutrients to grow strongly.
• Increase soil fertility:Cow manure helps improve soil structure, increase water holding capacity and aeration, and provides a large amount of organic matter to the soil, increasing crop productivity and quality.
• Reduces plant root rot: Cow dung helps improve soil structure and increase ventilation and water flow. This reduces the risk of plant root rot caused by water accumulation in the soil, providing a better environment for the plant’s root system to grow.
• Environmentally friendly:Cow manure does not contain toxic chemicals, helping to reduce the risk of environmental pollution and protect clean water sources.
• Provide and maintain a  useful microbial ecosystem:Cow manure contains many beneficial microorganisms, enriching the soil with microbial biomass and enhancing plant resistance.
• Reduce production costs:Using cow manure as organic fertilizer helps reduce costs for chemical fertilizers and takes advantage of available resources from livestock waste.

2. There are several types of cow dung

Before proceedingcompost cow manure, we need to determine the classification of cow manure to have a suitable method of composting cow manure. Normally, there are 3 popular types of cow manure today: dry cow manure, fresh cow manure and decomposed cow manure. Each type of cow manure corresponds to a separate composting method.

2.1 Fresh cow manure

Fresh cow manure is manure taken directly from the livestock barn and has not been processed. Therefore, although fresh cow manure contains many nutrients, it also carries some worrying risks, especially pathogens and harmful fungi. When using fresh cow manure to fertilize plants, these pathogens can penetrate and cause plant diseases. In addition, there is also the risk of weed seeds germinating in fresh cow manure, causing nutritional competition with the plants being cared for, reducing crop productivity.

Therefore, when using fresh cow manure, it is necessary to use methodscompost cow manureto  help cow manure decompose quickly and control the risk of plant diseases and kill weed sprouts in manure.

2.2 Dried cow manure

Dried cow manure is created by drying fresh cow manure. The moisture content of dried cow manure is very low. This drying process helps reduce moisture and prolong the shelf life of cow manure, making it easy to store and transport. When stored, dried cow manure is partially decomposed, so when proceedingcompost dry cow manureNeed watering to provide enough moisture and incubation timecompost cow manurefaster than fresh cow dung.

When using untreated dry cow manure, it can easily cause nutritional imbalance in the farmland. Organic matter in dried cow manure can accumulate in the soil if used excessively, causing a number of problems such as:

• Nutritional imbalance: When too much dry cow manure is used, the soil can become rich in organic matter without important nutrients such as nitrogen, potassium and phosphorus. This can lead to nutritional imbalance and reduced crop performance.
• Affects plant growth: Nutritional imbalances can make it difficult for plants to absorb nutrients needed for plant growth.

2.3 Decomposed cow dung

Decomposed cow manure is produced from handling and processing fresh or dried cow manure through composting or composting. This process helps cow manure decompose into a fertilizer product rich in organic matter and nutrients, while also eliminating pathogens, harmful fungi and weed seeds.

3. Traditional way of composting cow manure

Traditional way of composting cow manureis the methodcompost cow manureSimple, easy to make and does not require the use of any ingredients or biological products. There are 3 traditional methods of composting cow manure: hot composting, cold composting, and a combination of hot and cold composting.

The traditional way of composting cow manure is time-consuming and the composting efficiency is not high

3.1 Hot incubation method

Hot composting: Put cow manure in the pile, keep the humidity 60-70% and the temperature around 60 – 65 degrees Celsius. After 6 days, beneficial microorganisms in the cow manure will develop, helping the manure to decompose faster. After 60 – 80 days it can be used.

The steps to heat composting cow manure are as follows:

• Select incubation location: Choose a location with good water retention capacity to compost cow manure. This helps maintain the moisture needed for the composting process.
• Treats fillers and maintains protein: If cow manure contains a lot of fillers, you can use 1% lime powder to treat it. To maintain nitrogen in fertilizer, you can use 1-2% superphosphate. This helps provide the nutrients needed for the composting process.
• Carry out composting: Spread a layer of cow dung on the ground about 10-15cm thick, water it to provide moisture. Then, apply a layer of filler on top. Continue spreading cow manure, watering, mulching and watering until the material is gone. Make a pile of manure into a pyramid, about 1-2m in diameter, about 1.5-2m in height. Maintain compost pile moisture between 60-70%.
• Cover the compost pile:Use tarpaulin or plastic to cover the pile of manure to keep it moist and limit odor.
• Monitor the composting process: During the composting process, it is necessary to regularly check the pile to ensure the compost is properly composted. If you see the pile of manure is dry, add more water to keep it moist. If you see the pile of manure is rotten, you need to stir the manure so it is composted evenly.

3.2 Cold incubation method

Cold composting: Compress cow manure into layers and cover with soil, covering the surface of the compost pile to keep moisture. The cold composting process is anaerobic, causing cow manure to decompose more slowly but with better nutritional quality. It takes 5-6 months for cow manure to fully compost.

The method of composting cow manure in an anaerobic environment, also known as the cold compost method, has its own strengths and weaknesses. Here are some notable points about this method:

Advantages:

• Easier to do: The cold annealing method is often simpler and easier to perform than hot annealing, and does not require too much technical knowledge or special equipment.
• No need for high temperature: The cold annealing process does not require high temperatures like hot annealing. This can be considered an advantage if you want to maintain microbial diversity in the stool.

Disadvantages:

• Waste of time: This method takes more time than hot incubation. This incubation process lasts from 5-6 months or even 1 year.
• Difficult to destroy pathogens: Due to low temperatures, the cold composting method is difficult to completely destroy harmful pathogens in manure. This can increase the risk of transmitting pathogens to plants when using decomposed cow manure to fertilize plants.
• Need technical management: Although simpler, the cold composting method still requires regular care and management, especially moisture control, compaction, and proper storage.

3.3 Combine hot and cold incubation

Combine hot and cold composting: Hot composting for 6 days to develop microorganisms, then compact cow dung for cold composting. Helps shorten the time compared to just cold incubation. Cow manure usually composts for about 60 – 90 days before it can be used. The advantage of traditional cow manure composting is that it is simple, easy to do and does not require the use of any additional ingredients or products. Cow manure after composting is of good quality with high nutritional content. However, the disadvantage of the traditional way of composting cow manure is that the composting time is long and the cow manure after composting may still have a bad smell and not be completely decomposed.

4. How to compost cow manure using biological products

The use of probiotics tocompost cow manureis the most effective way to optimize composting and improve compost quality. Here are some benefits of composting cow manure with biological products:

• Stimulates useful microbial activity: Probiotics often contain beneficial microorganisms such as bacteria, fungi, and mycorrhizal bacteria. These microorganisms can help stimulate the composting process and help cow manure decompose faster.
• Destroy pathogens and weed seeds quickly: biological products have the ability to kill harmful pathogens in cow manure, reduce the risk of transmitting pathogens to plants and effectively kill weed seeds.
• Enhance nutrition: Biological products can provide additional nutrients to cow manure, increasing the nutritional value of decomposed products.
• Eliminate cow manure odor completely: Probiotics can help eliminate unwanted odors from the composting process and reduce the risk of environmental pollution.

There are 2 typesbiological products composted with cow manureThe most effective today are trichoderma mushrooms and the microbial product EMZEO specialized in composting. So what type of biological product should you use to effectively compost cow manure?

4.1 How to compost cow manure with trichoderma fungus

Trichoderma fungusis a safe biological product used in waste treatment and composting for organic agriculture. However, trichoderma mushroom is suitable for composting fresh cow manure on a small scale (household) with a small growing area. Furthermore, trichoderma fungus only works best at temperatures below 40 – 45 degrees Celsius and decomposes waste of plant origin (cellulose).

Trichoderma preparations need to be used properlycompost cow manureeffective. ReallyCComposting cow manure with trichoderma properlywill help decompose and kill toxins and pathogens effectively. Some important notes when usingTrichoderma preparations composted with cow manureas follows:

• It is necessary to use all trichoderma preparations at once. In cases where they cannot be used immediately, they must be stored in tightly closed bottles in a cool, dry place.
• Safe for humans and pets because trichoderma is a product of biological organic origin
• Do not mix trichoderma with lime powder during use. Lime is a substance with antibacterial properties, so it will kill trichoderma fungus

• Trichoderma is most effective when used with organic fertilizers, microbial fertilizers, etc. Trichoderma should not be used with inorganic fertilizers because the fungus in the product will be killed by the concentration of the fertilizer, thereby reducing the effectiveness of use significantly.
• If trichoderma is used with fertilizers or pesticides, it is necessary to ensure that they comply with the instructions for use on the packaging and the instructions of local agricultural extension officers.

• Composted cow manure can be used for crops after 30-45 days of incubation.

Note:

• Cow manure should be composted in a cool place, away from direct sunlight and rain.
• If cow manure is composted for a long time, clean water needs to be added to keep it moist.

5. How to compost cow manure by combining trichoderma fungus and EMZEO product

To compost cow manure that decomposes quickly and does not smell, the simplest and most effective way is to use a combination of trichoderma fungus and the product EMZEO to compost. Composting cow manure with trichoderma + EMZEO product will help farmers save 30 to 50% of the cost of using inorganic fertilizer. In addition, composted cow manure will help plants increase productivity and good quality as well as ensure that harmful pathogens will be effectively destroyed. Here it isHow to compost cow manure to decompose quickly, the most effective odor remover today.

The super simple and most effective way to compost cow manure quickly

5.1 Select a location to compost cow manure

Some tools that need to be prepared for the composting process include watering cans, shovels, rakes, hoes, etc. In addition, you also need to prepare tarpaulins, plastic bags, sacks, etc. to cover the sun and keep the compost warm during the composting process. The location chosen for composting should be areas with good dry soil or cement floors. You can also use plastic bags to line the ground.

In addition, you need to cut grooves around the composting area to ensure that compost water can flow into the small collection holes without running out. Warehouses or barns that are no longer in use with an area of ​​about 3m2 per ton of compost material are also suitable locations for composting cow manure. You can refer to this for more information.

5.2 Prepare materials for composting cow manure

The most optimal cow manure composting formula is based on the following ingredients:

• Cow manure (fresh or dried): 1.5 tons
• Filler: agricultural waste or plant residue, straw, sawdust, sugarcane bagasse, rice husk…: 2 – 3 m^3
• PreparationsTrichoderma Bacillus fungusDuc Binh: 2 – 3  packs of 200gr
• Rice bran: 3kg
• Composting molasses: 2 liters (Without skipping)
• Composting product EMZEO: 2 – 3 200gr packages (helps speed up composting and eliminate odors, killing pathogens more effectively)
• Clean water
• Mixing tool
• Tarpaulin cover
• Fused phosphorus: 15 – 20kg (If not omitted)

Prepare the necessary materials for the cow manure composting process

Note: C:N ratio (Carbon: Nitrogen) is very important in the process of composting cow manure and producing organic fertilizer. An appropriate C:N ratio of 25 – 30:1 helps the organic decomposition process take place effectively, quickly and without loss of nutrients in the compost pile. Therefore, when composting cow manure, it is necessary to mix the appropriate amount of fillers and organic waste.

5.3 The fastest way to compost cow manure

How to compost cow manure with trichoderma fungus combined with correct technical preparations

Step 1: Mix yeast water:Dissolve 2-3 packs of EMZEO 200gr, 2-3 packs of Trichoderma Bacillus Duc Binh 200gr, 2 liters of molasses, 3kg of rice bran in 30 liters of clean water. Yeast water is applied to the compost pile to speed up the composting process, eliminate odors, and kill pathogens.

Step 2: Mix cow manure, fillers and phosphorus well:Mix cow manure (fresh or dry), filler (organic waste), and phosphate well. This is an important step to create a foundation for the incubation process.

Step 3: Spread a layer of cow manure mixture and water with yeast

• Spread a layer of cow manure mixture on the compost with a thickness of 7 to 10cm.
• Water the composted yeast (mixed in step 1) on the cow dung layer.
• Continue repeating this process until you run out of ingredients.

Step 4: Add water to achieve incubation humidity

• Add water to the cow manure until it reaches a compost moisture level of about 50-55%. You can check the moisture level by gently grasping a portion of the compost, and if there is water dripping slightly between your fingers, that is the required moisture level.

Step 5: Make piles and cover with tarpaulin

• Make a pile of cow dung and cover it with tarpaulin. The size of the compost pile should be from 1.6 to 1.8m in height and 2.2 to 2.5m in radius.
• Incubation time is about 25 to 30 days. Make sure to stir the pile evenly after the first 15 days, then stir the pile again for the next 10-15 days.
• A sign of the success of the composting process is that the heap temperature increases sharply in the first 3 days (up to 55-60 degrees Celsius), then the cow dung decomposes quickly, becomes humus, and does not have a foul smell.
• After about 3 – 4 weeks, the pile temperature gradually decreases to normal temperature when the composting process is completed. The size of the compost pile is only 1/3 of the original, and the final product is quality organic fertilizer.

Step 6:Grind, sift, package and use

After you successfully compost cow manure, the next process is grinding, sifting and bagging for storage and use. If you do not have grinding equipment, bagging composted cow manure is a good way to avoid losing nutrients in cow manure and preserve it for a longer time.

6. Why is it necessary to compost cow manure before fertilizing plants?

In fact, fresh or uncomposted cow manure will contain many microorganisms that are harmful to plants. In addition, cow manure also contains a lot of impurities, grass seeds, etc. Therefore, if cow manure is used directly, it will have negative effects on plants. The bad effects that need to be mentioned are:

• The first factor that needs to be mentioned is that they cause diseases in plants. Specifically, when exposed to the tree, it is easy to encounter conditions such as root rot, yellow leaves, premature death or fungal diseases…
• In addition, plant pathogens can also affect consumers. Specifically, bacteria such as E. coli, Salmonella… They will cause poisoning and diarrhea for consumers when using foods fertilized with fresh cow manure.
• In addition, fresh cow manure that is not composted also reduces soil quality. Specifically, the soil has reduced pH and reduced organic content. This is the factor that reduces protein content and vitamin content for plants.
• Create conditions for weeds to grow. As we know, fresh cow dung has a lot of grass and they will compete with plants for space, light, nutrients and water.

Therefore, it is necessary to compost and fertilize before fertilizing. This is also considered an important step to eliminate harmful agents and produce beneficial agents to balance the plant’s nutrition.

7. How to use composted cow manure to fertilize plants

Using composted cow manure with biological fertilizers will help significantly improve plant growth, provide nutrients, improve soil quality, and increase crop productivity and quality. Cow manure is used in almost all stages of plant growth of all types of plants:

• Primer fertilizer: Applying decomposed cow manure as a mulch on the soil surface helps provide nutrients to plants throughout the growing period.
• Top dressing: Use decomposed cow manure to promote plant growth during important stages such as the flowering or fruiting stage.
• Fertilize after harvest: After harvesting crops, applying decomposed cow manure helps re-supply nutrients to the soil, preparing for the next planting season.
• Fertilize and improve soil: Decomposed cow dung also has the ability to improve soil by providing organic matter and improving soil structure. This can promote the growth of plants on weak soil.

Treated cow manure is a high-quality organic fertilizer, capable of effectively improving soil and promoting strong plant growth. The way and amount of fertilizer for plants depends on the type of plant as well as its stage of development.

• Colored vegetables: Sprinkle cow manure evenly on the bed surface at an amount of 100 – 150 kg/acre in the Northern region. This helps provide nutrition for vegetable plants to grow well, be rich in nutrients and taste better.
• Fruit trees and industrial trees: For small trees or newly planted trees, you can dig a trench around the base and fertilize 1 – 1.5 kg/root. For perennial trees or large fruit trees, you can fertilize 3 – 4 kg/root.
• Ornamental plants and roses: Apply cow manure to the roots of ornamental plants or roses with an amount of 0.2 – 0.5 kg/root. After fertilizing, water the soil and plants.
