Understanding of microbial fertilizer (bacterial fertilizer)

1. The difference between raw fertilizer and mature fertilizer:

Organic matter is made up of macromolecules of polymers, such as bone meal, fish meal, meat meal, soybean, rice bran. These organic matter are called "raw fertilizer". They can not be absorbed and utilized by plants, but must go through the process of microbial fermentation before they can be decomposed into organic nutrients (mature fertilizer) that can be absorbed by flowers and plants, that is to say, raw manure can be decomposed by complete fermentation before it can be decomposed into mature fertilizer, which is called Composting.

2. Raw fertilizer, semi-mature fertilizer and full-ripe fertilizer:

Only full-ripe fertilizer can be used in planting pot without any scruples, because full-ripe fertilizer no longer produces fermentation heat, harmful gases, pathogens, diseases and insect pests. However, the organic nutrients produced by full-ripe fertilizer during the fermentation period, including amino acids, nucleotides, vitamins, plant growth hormones, antibiotics. Most of them have disappeared, and the fertilizer effect has lost a lot. On the contrary, manure organic matter is decomposed by microorganisms (beneficial bacteria or pathogens) in the planting basin to produce a variety of fresh and effective organic nutrients to provide for plant growth in time before being destroyed.

. Therefore, effective fertilizer is the advantage of using raw fertilizer, but the fermentation heat produced during fermentation and a variety of toxic gaseous products (such as ammonia and hydrogen sulfide) are harmful to plants. At the same time, a large number of nitrogen sources and oxygen are consumed due to the mass reproduction of microorganisms, resulting in nitrogen deficiency (nitrogen hunger) and hypoxia in crops. In raw fertilizer, pathogens multiply in large numbers, and it also contains disease, insect eggs and weed seeds, so the harm of raw fertilizer far outweighs its benefits. After all, fermented compost is safer than raw fertilizer. With the development of modern science and technology, all kinds of materials can be extracted from the soil.

Soil microorganisms beneficial to farming are purified, cultured and mass-produced into comprehensive microbial preparations. therefore, a new generation of organic composting can produce microbial semi-mature fertilizer with both fresh organic fertilizer and free from the harm of fermentation.

3. Microbial semi-ripe composting (bacterial manure):

After the organic material is mixed, the fermentation process is controlled by beneficial soil microorganisms, moisture and aeration instead of natural fermentation. at the initial stage, the organic matter decomposes and emits high heat (50 degrees-75 degrees) to kill pathogenic bacteria, insect eggs and weed seeds, and then slowly decomposes into semi-mature fertilizer at the appropriate temperature (40 degrees-52 degrees), and uses its energy to cultivate a large number of beneficial microbiota at the same time. In this way, it can not only prevent the root burning caused by fermentation and the harm of ammonia and hydrogen sulfide in the future, but also avoid the phenomenon of hypoxia and nitrogen deficiency caused by the mass reproduction of microorganisms consuming oxygen and nitrogen.

The advantage of beneficial microbiota can also inhibit the reproduction of pathogens, improve soil and provide fresh organic nutrients. The effect of bacterial fertilizer is very different from that of raw fertilizer or full-ripe compost, and the amount required is greatly reduced. Long-term use can enhance the soil fertility, and the harvest is getting more and more abundant year by year. Microbial semi-ripe compost (bacterial compost) can be used as a strain of upper soil microorganisms, because it is a semi-ripe compost, so it must be used as raw fertilizer to operate in the same way as raw fertilizer.

The use of microbial semi-mature fertilizer can avoid the production of hydrogen sulfide and ammonia and the reproduction of pathogens. It can also keep a large number of microbes that are beneficial to crops.
