How Should compost the Chicken Dung Reasonably ?

Notice:

If chicken manure is not treated or decomposed fully and applied directly to crops, there are great harms and hidden dangers.

                                    

1.    Infection of diseases and pests.

Feces contain coliform bacteria, nematodes and other bacteria and pests. Direct use will lead to the spread of diseases and and pests, and also affect the human health of edible agricultural products. When unripe organic materials are fermented in soil, it is easy to breed bacteria and insect pests, which will harm plant, especially for fruit trees, the use of non-decomposed chicken manure can easily lead to the outbreak of nematodes at the root of the fruit trees, which will akes away the nutrients in the root, impede the transport of water and nutrients, and cause the fruit trees to be weakened (yellow leaves) and decayed (root rot) to die.

2.    Burn seedlings.

If raw dung are applied to the siol, they will be fermented under the activity of microorganisms when the fermentation conditions are available. the heat generated by fermentation will affect the crop growth and burn down the crop roots, resulting in plant death in serious cases.

3.    Poison gas.

In the process of decomposition, harmful gases such as methane and ammonia are produced, resulting in acid damage, root damage to soil and crops. Especially in the greenhouse, the damage is more serious.

4.    Oxygen deprivation of soil.

                                               

In the process of decomposition, organic matter consumes the oxygen in the soil, making the hypoxia of soil temporarily, which will inhibit the growth of crops.

5.    Fertilizerl effect is slow.

Unfermented organic fertilizers cannot be directly absorbed and utilized by crops, they can only be absorbed and utilized by crops if they are decomposed into a quick effect state. Therefore, when unfermented organic fertilizers are applied directly, the fertilizer effect will be slowed down.

6.    High cost

Direct use without treatment of organic materials, with large volume, low effective ingredients, inconvenient transportation and high cost.

  what is the criterion for judging sufficient decomposing of chicken manure?

  No odor, white hyphae, chicken manure with loose form, above 3 conditions at the same time can be judged roughly chicken excrement is already fermented well. Under natural conditions, it usually lasts for 2-3 months. When the composting temperature reaches 60 or 70     degrees, it needs to be overturned for 3-5 times. If bactericide is added, this process will be greatly accelerated. With suitable fermentation compost turning machine, depending on the ambient temperature, it generally takes 20-30 days, but it can be finished within 7-10 days     under the conditions of factory production. After the granulation, bacterial addition, mineral supplement and other processes, it will eventually become commercial organic fertilizer.

  The advantages of fermented chicken manure

 1. Produce a variety of enzymes and inhibit the transmission soil diseases.

  2. The beneficial microbial flora is continuously active, slowly releasing the nutrients required for crop growth.

  3. Improve soil physical property, keep the soil soft, increase soil water and fertilizer conservation capacity;

  4. Green and environmental protection , improve fertilizer efficiency.

  5. root and seedling become strong, increase the disease prevention and disease resistance of crops.
