How to ferment sheep manure? I want to grow flowers with fermented sheep manure. The process is more detailed. Thank you!

Nutritional components in sheep manure

Sheep manure contains: organic matter 24-27%, nitrogen 0.7-0.8%, phosphorus 0.45-0.6% and potassium (K2O)0.4-0.5%.

Can sheep manure be directly used as fertilizer?

1, sheep manure cannot be directly used as fertilizer.

2. Sheep dung contains bacteria and pests, such as Escherichia coli and nematodes. If it is not decomposed and used directly, it is easy to spread pests and diseases.

3. Sheep manure has not been fermented and decomposed. Once it is directly applied to the ground, once the conditions are right, it will generate a lot of heat, causing plants to burn their roots and seedlings.

4. Sheep manure needs to consume oxygen in the soil during fermentation, which will lead to short-term hypoxia in the roots of plants and affect the growth of crops, and harmful gases such as methane and ammonia may be produced in this process.

5. Sheep manure does not decompose, and the nutrients in its fertilizer mostly exist in organic or slow-acting state, which cannot be directly absorbed and utilized by crops.

Benefits of sheep manure organic fertilizer

1, applying sheep manure in soil has many benefits. Sheep manure contains a lot of nutrients, such as nitrogen, phosphorus and potassium, a variety of trace elements and sugars.

2. After being applied to the soil, the harm of heavy metals in the soil to crops can be effectively reduced.

3. Increase the organic matter content in the soil. Sheep manure can promote the reproduction of a large number of beneficial microorganisms, thus improving the aggregate structure of soil, making soil loose and fertile, improving the ability of water and fertilizer conservation and reducing the loss of fertilizer and water.

fermentation method

principle

Rotten sheep manure organic fertilizer generally needs two stages, namely the first high-temperature composting fermentation stage and the second aging stage. Unstable organic matter is transformed into stable humus through decomposition process and microbial action. Its temperature change can define whether it decomposes or not.

The second stage: at the beginning, the temperature drops, the oxygen absorption rate drops, and the smell disappears completely. Compared with the first composting, the second composting is essential, because the second composting can degrade refractory organic matter and re-establish mesophilic microbial colonies, thus contributing to the decomposition of organic fertilizer, reducing phytotoxic substances and inhibiting pathogenic bacteria.

The first stage: through the proportion of raw materials and substrates, the compost heap will absorb high oxygen, produce high temperature, reduce a large number of degradable volatile solids, gradually reduce odor, and gradually change the color of the compost heap, so it is necessary to maintain good ventilation and humidity control.

Heating stage: the decomposition temperature of organic fertilizer rises to 45℃, which is mainly composed of actinomycetes, fungi and bacteria, and mainly decomposes sugar and starch. Even active creatures, animals and animals are involved. High temperature stage: when the decomposition temperature reaches above 45℃, mesophilic microorganisms are inhibited and thermophilic bacteria are dominant. Soluble organic matter continues to be oxidized and decomposed, and complex organic matter (cellulose, hemicellulose, protein, lignin) also begins to decompose. About 50℃ (thermophilic fungi and actinomycetes); About 60℃ (thermophilic bacteria and actinomycetes); About 70℃ (most microorganisms can't adapt). The optimum decomposition temperature is 55℃, because most microorganisms are most active at this temperature, and it is easy to decompose organic matter, and most germs, eggs and weed seeds will be killed. Cooling stage: thermophilic microorganisms began to multiply again, taking advantage and further decomposing the residual refractory organic matter. At this time, the microbial activity decreases, the oxygen demand of compost decreases, the temperature decreases, and the pile gradually stabilizes.
