Organic fertilizer mainly comes from the carbonaceous materials that plants and/or animals apply to the soil to provide plant nutrition as its main function. It is processed by biological materials, animal and plant wastes and plant residues, and eliminates toxic and harmful substances. It is rich in a lot of beneficial substances, including: a variety of organic substances, peptides and rich nutrients including nitrogen, phosphorus and potassium. It not only provides comprehensive nutrition for crops, but also has long fertilizer effect. It can increase and update soil organic matter, promote microbial reproduction, improve soil physical and chemical properties and biological activity, and is the main nutrient for green food production.
Organic fertilizer in a broad sense: commonly known as farmyard manure, including a variety of animals, plant residues or metabolites, such as human and animal waste, straw, animal debris, slaughterhouse waste.
Biological bacterial fertilizer (microbial fertilizer) is a kind of product that causes the crop to obtain a specific fertilizer effect by the life activity of microorganisms, and is a kind of fertilizer used in agricultural production. It has a history of nearly 50 years in China. The evolution of the name from the rhizobial agent-bacterial fertilizer-microbial fertilizer has illustrated the process of the development of microbial fertilizer in China. For a long time, there have been some misunderstandings and prejudices about the concept of microbial fertilizer in society.
One view is that it is highly effective, treating it as a universal fertilizer, and even threatening to completely replace fertilizer;
Another view is that it is not a fertilizer at all.
In fact, both are biased. Many years of experiments at home and abroad have proved that inoculation of leguminous crops such as soybeans and peanuts with Rhizobium can improve the symbiotic nitrogen fixation efficiency, and indeed has the effect of increasing production. Reasonable application of other bacterial fertilizers for seed dressing or application of microbial fertilizers also has an effect of increasing yield on non-legume crops, and There is no effect that chemical fertilizers can't. Therefore, we believe that it is a fertilizer, and it is different from traditional fertilizers and organic fertilizers in terms of concept and connotation.
Microbial fertilizer is a living fertilizer, and its function is mainly achieved by the life activities of a large number of beneficial microorganisms it contains.
Only when these beneficial microorganisms are in vigorous breeding and metabolism can material transformation and beneficial metabolites continue to form.
Therefore, the type of beneficial microorganisms in microbial fertilizers and the vitality of life activities are the basis of their effectiveness, unlike other fertilizers based on the form and amount of major elements such as nitrogen, phosphorus and potassium. Because microbial fertilizer is a living preparation, its fertilizer efficiency is closely related to the number, intensity and environmental conditions of living bacteria, including temperature, water, pH, nutrient conditions and the original microbial repulsion of soil in the soil. Pay attention when applying.
As a substitute for chemical fertilizers, organic fertilizers and biological bacterial fertilizers are one of the foundations of organic agriculture and green agriculture. Due to their respective shortcomings, a fertilizer with both advantages, bio-organic fertilizer, has emerged and rapidly promoted. :
Bio-organic fertilizer refers to a combination of specific functional microorganisms and organic materials mainly composed of animal and plant residues (such as livestock and poultry manure, crop straw, etc.) and treated by harmless treatment and decomposed organic materials. Fertilizer for fertilizer effect.
Advantages of bio-organic fertilizer:
1 Bio-organic fertilizer compared with chemical fertilizer:
1) Bio-organic fertilizers are complete in nutrient elements; there are only one or several nutrient elements in fertilizers.
2) Bio-organic fertilizer can improve the soil; the frequent use of chemical fertilizers will cause soil compaction.
3) Bio-organic fertilizer can improve product quality; excessive application of chemical fertilizer leads to poor product quality.
4) Bio-organic fertilizer can improve the rhizosphere microflora of crops and improve the resistance of plants to pests and diseases; chemical fertilizers are single crop microbial populations, prone to pests and diseases.
5) Bio-organic fertilizer can promote the utilization of chemical fertilizers and improve the utilization rate of chemical fertilizers; the use of chemical fertilizers alone can easily cause the fixation and loss of nutrients.
2 Bio-organic fertilizer compared with refined organic fertilizer:
Refined organic fertilizer is a commercial organic fertilizer that is packaged and sold after drying and smashing livestock manure.
1) The bio-organic fertilizer is completely decomposed, does not burn roots, and does not rotten seedlings; the refined organic fertilizer is not decomposed, and is directly decomposed in the soil after use, which may cause burning phenomenon.
2) Bio-organic fertilizer is decomposed by high temperature, killing most pathogens and eggs, reducing the occurrence of pests and diseases; refined organic fertilizer is not decomposed, and will cause underground pests when it is decomposed in the soil.
3) Beneficial bacteria are added to the bio-organic fertilizer, which reduces the occurrence of diseases due to the occupancy effect of the flora; the refined organic fertilizer kills all the microorganisms inside due to high-temperature drying.
4) Bio-organic fertilizer has high nutrient content; refined organic fertilizer has caused nutrient loss due to high temperature treatment.
5) The bio-organic fertilizer is deodorized, light in smell and almost odorless; the refined organic fertilizer is not deodorized, and the stench is formed when the moisture is returned.
3 The difference between bio-organic fertilizer and farmyard manure (traditional organic fertilizer):
1) The bio-organic fertilizer is completely decomposed, and the mortality rate of the eggs is over 95%; the farmer's fertilizer is simple to pile up, and the mortality rate of the eggs is low.
2) Bio-organic fertilizer is odorless; farmyard manure has stench.
3) The application of bio-organic fertilizer is convenient and uniform; the application of farmyard manure is inconvenient and the application of fertilizer is not uniform.
4 The difference between bio-organic fertilizer and biological bacterial fertilizer:
1) Bio-organic fertilizer is cheap, about 1,000 yuan per ton; biological fertilizer is expensive, and it costs 10,000 yuan per ton.
2) Bio-organic fertilizers contain functional bacteria and organic matter, which can improve the soil to promote the release of soil-fixed nutrients; biological bacterial fertilizers only contain functional bacteria, and promote the use of soil-fixed fertilizers through functional bacteria. 3) The organic matter of bio-organic fertilizer itself is the environment in which the functional bacteria live. It is easy to survive after being applied to the soil; and the functional bacteria of the bio-fertilizer may not be suitable for the soil environment. (Organic Fertilizer Agrochemicals)

Probiotics are a class of active microorganisms that are beneficial to the host by colonizing the human body and changing the composition of the flora in a certain part of the host. By regulating the immune function of the host mucosa and system or by regulating the balance of intestinal flora, promoting nutrient absorption and maintaining intestinal health, resulting in the production of single microorganisms or mixed microorganisms with well-defined composition that are beneficial to health.
