What is the difference between organic fertilizer and microbial fertilizer?

Organic fertilizer is mainly used on plants and/or animals, and is a carbon-containing material applied to the soil to provide plant nutrition as its main function. It is processed from biological substances, animal and plant wastes, and plant residues, eliminating toxic and harmful substances, and is rich in a large number of beneficial substances, including: a variety of organic acids, peptides, and rich nutrients including nitrogen, phosphorus, and potassium.

It can not only provide comprehensive nutrition for crops, but also has long fertilizer effect, can increase and renew soil organic matter, promote microbial reproduction, improve the physical and chemical properties and biological activity of soil, and is the main nutrient for green food production. Organic fertilizer in a broad sense: commonly known as farmhouse fertilizer, including various animal and plant residues or metabolites, such as human and animal manure, straw, animal residues, slaughterhouse waste, etc.

Biological fertilizer (microbial fertilizer) is a product that causes crops to obtain specific fertilizer effects due to the life activities of microorganisms, and is a kind of fertilizer used in agricultural production. It has a history of nearly 50 years in China, from rhizobia agent - bacterial fertilizer - microbial fertilizer, from the name of the evolution has explained the gradual development process of microbial fertilizer in China. For a long time, there have been some misunderstandings and prejudices in society about the perception of microbial fertilizers.

One view is that it is highly fertiliserable, regards it as a universal fertilizer, and even threatens to completely replace chemical fertilizer; Another view is that it is not fertilizer at all. Actually, both of these are prejudices. Many years of experiments at home and abroad have proved that inoculating soybeans, peanuts and other leguminous crops with rhizobia can improve the efficiency of symbiotic nitrogen fixation, and indeed have the effect of increasing yield.

Therefore, we consider it to be a fertilizer, which is different from traditional chemical fertilizers and organic fertilizers in terms of concept and connotation. Microbial fertilizer is a living fertilizer, and its role is mainly completed by the life activities of a large number of beneficial microorganisms it contains. Only when the life activities of these beneficial microorganisms are completed.

Only when these beneficial microorganisms are in vigorous reproduction and metabolism can the transformation of substances and beneficial metabolites continue to be formed. Therefore, the types of beneficial microorganisms in microbial fertilizers and whether their life activities are vigorous 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 fertilizers are live preparations, their fertilizer efficiency is closely related to the number and intensity of viable bacteria and the surrounding environmental conditions, including temperature, moisture, and pH.

Nutrient conditions and the rejection of indigenous microorganisms in the soil have a certain impact, so attention should be paid to the application of them.

1. Different definitions.

1. Microbial agent: refers to the live bacteria preparation made by using the fermentation broth of the porous substance adsorption of the bacteria after the industrial production and multiplication of the target microorganisms (effective bacteria).

Second, the characteristics are different.

1. Microbial agent: It is the carrier of microorganisms, does not contain nutrients, and promotes the release of nutrients from organic fertilizers, fertilizers and mineral nuclei in the soil through the physiological metabolic activities of microorganisms after use.

2. Organic fertilizer: It contains a large number of beneficial substances, such as nitrogen, phosphorus, potassium, organic acids, peptides, etc.

Third, the usage is different.

1. Microbial agents: mostly used as base fertilizer, seed fertilizer, and top dressing.

2. Organic fertilizer: the fertilizer has a long effective period, and it is mostly used as base fertilizer.

The difference between microbial inoculants and organic fertilizers.

Fourth, the role is different.

1. Microbial agents: It can improve crop resistance, improve crop quality, inhibit the breeding of harmful bacteria in the soil, and regulate the physical and chemical properties of the soil.

2. Organic fertilizer: It can increase the content of organic matter in the soil, promote the reproduction of microorganisms, improve the physical and chemical properties and biological activity of the soil, and provide comprehensive nutrition for crops.

The focus is different:Organic fertilizer is a kind of fertilizer, but the foothold of biological fertilizer is on the fungus, which is more inclined to its function, such as improving fertility, promoting the release of insoluble mineral nutrients in the soil, and enhancing the ability of plants to resist disease and stress.

It is used in different ways:Organic fertilizer is generally used as base fertilizer or top dressing during the growth period; Bacterial fertilizer can be used for seed dressing, base fertilizer, top dressing, dipping roots, etc.

The conditions of use are different:Organic fertilizer generally has no special restrictions on burning, but bacterial fertilizer is "Zen slippery and virtual", so it can not be mixed with pesticides, fungicides, nor can it be exposed to sunlight for a long time, and the moisture content, temperature, pH conditions of the soil will also affect the effect of bacterial fertilizer.
