Cow dung fertilizer for plants

Cow dung is a common manure fertilizer. Through reasonable fermentation, it can be turned into high-quality farmyard manure for fertilizing food crops, vegetables and fruit trees. So, does the application of cow dung require fermentation? Tianci’s introduction based on practical experience is as follows:

Undecomposed cow dung can be used as base fertilizer in spring, autumn and winter, but it needs to be treated with insecticide and sterilization. Undecomposed cow dung contains a large amount of pathogenic bacteria, insect eggs and weed seeds. If it is directly applied to flowerpots, it may lead to the increase of diseases, insect pests and weeds of flowers. Insecticides and fungicides can be selected according to common diseases and insect pests for treatment and later use.

 

Undecomposed cow dung will undergo secondary fermentation after being applied to the soil, which will generate huge heat and cause burning of roots and seeds. The fermentation speed is fast in summer, so try to avoid the application of immature cow dung. Cow dung is fermented slowly in the low temperature season. A small amount of dry cow dung is applied as a base fertilizer in a large flower pot, and 5 cm of nutrient soil is sprinkled on it, and then sowing or transplanting flowers will not have a big impact on the flowers. However, do not apply a large amount of cow dung to large flower pots, and it is best not to do this for general small flower pots, otherwise the flowers will die or wither.

Fresh cow dung has a high water content and needs to be piled up to allow the excess water to naturally decrease. When the water content is reduced to 60-65%, fermentation can be performed. The easiest way is to pile the cow dung to a height of 60-80 cm, insert corn stalks in the middle, which will help to speed up the decomposing speed, paste a layer of soil on the outside, and then cover it with a film. Turn the heap when the temperature rises above 65°C to ensure even fermentation. According to the actual situation, it is necessary to add water if necessary. When the temperature is lowered to normal temperature again, the cow dung will be fermented successfully.

The factory-produced organic fertilizer will be fermented by adding bacterial agents, and the fermentation speed is faster and the quality is better. The fermented cow dung has no odor and is in the form of loose powder. The straw inside is basically decomposed, and the impurities are removed. After sieving, it can be fertilized as nutrient soil in proportion. Dry cow dung fermentation needs to add water to keep the moisture content of cow dung at 60-65%, and the rest is similar to the fermentation method of fresh cow dung. If there is less cow dung, you can also drain the excess water, put it in a plastic bag, and ferment it in a place with a higher temperature. It is also necessary to add water and stir to promote even rot.

Because salt is often added in the breeding process, the salt content of cow dung is relatively high. After being used as a base fertilizer, it can be discharged from the flowerpot through multiple waterings. This problem does not need to be considered when raising flowers. Before the decomposed cow dung is used as nutrient soil, it is best to dilute it with water again, and then make nutrient soil when the humidity is suitable, so as to avoid the occurrence of poor growth and development caused by excessive salt.

Undecomposed cow dung is used in the low temperature season, but it needs to be treated with insecticide and sterilization.

Undecomposed cow dung will undergo secondary fermentation. In summer, the fermentation speed is fast and heat is generated, which will cause root burning and seed burning. Try to avoid using immature cow dung.
