How to distinguish microbial organic fertilizer and microbiological fertilizer?

Microorganic fertilizers & microbiological fertilizers are quite popular fertilizers and are used a lot by farmers and farmers in agriculture. Together with  BSF Smart Farm, learn & distinguish these 2 fertilizers to understand the characteristics, improve efficiency & usability for each type of fertilizer.

1. Bio-fertilizers & microbial fertilizers

What is microbial organic fertilizer?

  1. Microbial organic fertilizer is an organic fertilizer containing from one to many strains of beneficial microorganisms, which is processed by treating and mixing organic materials and then fermenting with microbial strains according to the ratio of microorganism. ratio of 15% organic matter and  ≥ 1×106 CFU/mg for each type of microorganism strain.
  2. This fertilizer not only provides enough multi-, medium-, and micro-mineral nutrients for plants, but also dissolves inorganic substances in the soil into nutrients for easier absorption by plants, and at the same time increases fertility. for the soil, adding beneficial microorganisms to effectively prevent pests and diseases.
  3. The use of this fertilizer contributes to minimizing the harmful effects of chemicals on agricultural products due to the abuse of chemicals such as chemical fertilizers and pesticides, enhancing environmental protection, towards sustainable agricultural production.

What is Biofertilizer?

  1. Microbiological fertilizer is a preparation containing carefully selected strains of microorganisms, to ensure that the technical conditions are met for the types of microorganisms allowed to be used as biological products.
  2. Microbial strains used to produce microbial fertilizers: soluble microorganisms, nitrogen-fixing microorganisms, organic matter-degrading microbial fertilizers, plant growth-stimulating microorganisms,… all All must comply with the standards set by state regulatory agencies.
  3. Bio-fertilizer possesses many outstanding advantages, in line with trends such as: ensuring safety for soil, plants, people and the environment, so in terms of application, micro-fertilizers are widely used in the field of bio-fertilizers. agriculture today.
  4. In addition, this type of fertilizer also stimulates the growth and development of plants, helps improve crop quality, prevents the risk of pests and diseases and does not drain the plant.

2. Classification of microbial organic fertilizers and microbial fertilizers

Microorganic fertilizer Microbial manure
About Basic Is organic treated by fermentation with beneficial microorganisms. It is a preparation containing beneficial microorganisms.
About the carrier Black soldier fly droppings manure, peat, coffee husks, sugarcane sludge, etc. Usually use humus as filler, microorganism carrier.
About the microbial density From 1×106 1.5×108
About microbial strains Nitrogen-fixing microorganisms, phosphorus-degrading, growth-stimulating microorganisms, antagonistic microorganisms against bacteria, fungi, … Microorganisms that fix nitrogen, decompose phosphorus, and decompose cellulose.
Methods used Apply directly to the soil. Mix into seeds, plant roots, apply directly to the soil.

3. Microbial strains used to produce microbial fertilizers and microbial organic fertilizers:

a. Phosphate-degrading microorganisms:

  • Microorganisms that are able to convert insoluble phosphorus compounds into easily usable plant substances are called phosphorus-dissolving microorganisms.
  • They have the ability to dissolve many different insoluble phosphorus compounds, creating conditions to improve productivity and efficiency in the use of phosphate fertilizers for plants.

b. Nitrogen fixing microorganisms:

  • Nitrogen fixation is the process of reducing molecular nitrogen to usable plant nitrogen and is carried out by bacteria of the genera Clostridium, Azospirillum, Azotobacter, symbiotic bacteria such as Rhizobium in the root nodule family of plants. Beans, lichens (mushrooms and cyanobacteria of the genus Nostoc) and freshwater mulberry flowers symbiotic with cyanobacteria such as Anabaena, etc. These microorganisms will fix nitrogen from the air and convert it into nitrogen-containing compounds. for plants and soil, improve plant tolerance and increase soil fertility.

c. Cellulose-degrading microorganisms:

  • It has the effect of processing and decomposing cellulose components in bran, bagasse, straw, etc. to make it easier for plants to absorb. The use of microorganisms to treat organic substances containing cellulose is highly effective and is being widely applied.

d. Plant Growth Promoting Rhizobacteria:

  • These bacteria inhibit pathogens through competition for nutrients, secrete enzymes or create antibiotics that increase resistance to help plants less pests and diseases, creating conditions for growth and development. better, contributing to increase productivity and quality of agricultural products over the seasons.

With the sharing from this article, BSF Smart Farm hopes to help readers and farmers distinguish the difference between two types of microbial organic fertilizers and microbiological fertilizers, making it easier to choose the type of fertilizer. fertilizer put into use to bring high efficiency.

    Its such ɑs you learn my mind! You seem to սnderstand ɑ lot about this, such as you wrote the guide in it or something.
    I feel that you simply can do with a few p.c.
    to force the message house a little bit, hоwever other than that,
    this is fantaѕtic blog. An excellent read. I will certainly be back.
