Reasonable knowledge of manure

●Advantages:

Advantage 1: The nutrients contained are relatively comprehensive, and the fertilizer effect is stable and long-lasting. It not only contains rich organic matter and various large, medium and micronutrient elements, but also contains some substances that can stimulate root growth and various beneficial soil microorganisms.

Advantage 2: Improve soil structure Rich in humic acid, which can promote the formation of soil aggregate structure, make the soil soft, improve soil moisture and air conditions, and facilitate root growth; increase soil fertility and water retention; increase ground temperature, promote soil The activity and reproduction of beneficial microorganisms, etc.

Advantage 3: Adjust soil temperature Manure can be divided into hot, warm and cool, and has the effect of regulating soil temperature.

●Hidden dangers (must be decomposed and fermented)

Hidden danger 1: immature manure, especially poultry manure, has a high salt content, which can easily salinize the soil and increase the concentration of soil salt. In severe cases, it will cause the seeds not to germinate, burn the seedlings, and burn the roots. It also produces harmful gases that poison plants.

Hidden danger 2: There are many germs, insect eggs, weed seeds, etc. in poultry manure, without high-temperature fermentation, it is easy to bring adverse effects to plants, and it is also easy to cause diseases and insect pests.

Hidden danger 3: Due to source problems, some manure contains harmful substances such as heavy metals and antibiotics, which will poison plants and affect the safety of agricultural products.

●The method of decomposing manure

One is to combine the high-temperature stuffy shed to decompose the manure. In summer, the shed has a long leisure period, and it can be combined with high temperature and stuffy shed to decompose the manure. The process of decomposing and fermenting is also a process of improving the soil. During the fermentation and decomposing process, the microorganisms in the soil are very active and can promote the formation of soil aggregate structure.

The second is boring. There is enough time for natural stack retting and fermentation. In order to ensure the stability and safety of the effect, when the time is short, biological fermentation decomposer can be used when the stack is stuffy and decomposed. Commonly used are EM, ETS fermentation bacteria, etc., to ensure safety, harmlessness and shorten the fermentation time.

In fact, most of the factory-based manure processing methods are relatively formal and safe. If you feel that the processing is too troublesome and you are afraid that the processing is not in place, you can directly buy factory-processed organic fertilizers.
