What is Bio-Organic Fertilizer? How to Use the Right Technique

The demand for fertilizers, especially clean fertilizers, is increasingly focused in sustainable organic agriculture. Let’s learn with BSF Smart Farm the origin of bio-organic fertilizer, a fertilizer with many advantages.

What is Bio-Organic Fertilizer?

Bio-organic fertilizers are organic fertilizer products derived from natural organic raw materials containing one or more types of beneficial microorganisms, processed by mixing and treating raw materials. organic materials by fermentation with such microorganisms. For the purpose of destroying pathogens in raw materials and improving the content of nutrients contained in fertilizers to provide plants.

From the raw materials available in daily life such as cattle and poultry manure.. you can completely make your own bio-organic fertilizer at home without having to use any modern methods. any.

The process of bio-organic fertilizer production is indispensable for the participation of one or more strains of microorganisms in order to destroy the pathogens present in the raw materials and increase the nutrient content to help plants grow.

Benefits of Bio-Organic Fertilizer

  • Bio-organic fertilizers have the common characteristics of organic fertilizers, providing multi-medium-micronutrients for plants, helping to balance and improve the soil effectively.
  • Bio-organic fertilizers are known as environmentally friendly, low-toxic, non-polluting fertilizers, saving raw materials from available sources and minimizing investment costs for fertilizers.
  • Bio-organic fertilizers also have the ability to promote strong activity of microorganisms in the soil, converting nitrogen in the air into a form that plants can absorb,
  • Decompose substances that are difficult to absorb into easily absorbed substances, produce a number of substances capable of stimulating the growth of plants, decompose toxins accumulated in the soil for a long time…
  • Bio-organic fertilizers also help balance pH, maintain soil fertility by keeping the original and increasing soil structure,
  • Add a large amount of humus to the soil and serve as food for soil microorganisms, inhibiting and destroying pathogens that exist in the soil.
  • Provide some antibiotics to stimulate plant immunity to overcome harmful pests and diseases, protect the living environment by reducing the amount of pesticides.

Advantages of Bio-Organic Fertilizer

 

  • It is used to improve the soil, maintain and improve the fertility and fertility of the arable land in a long and sustainable way.
  • Simple to use, no fear of dead plants, no worries about soil degradation or acidification, alum, etc.
  • Provide enough essential macronutrients, intermediates and micronutrients for plants that chemical fertilizers do not have.
  • Can be used for all periods and stages of plants: new planting, flowering, fruiting, …
  • Increases nutrient absorption efficiency by providing microorganisms that break down indigestible substances (insoluble, indigestible) into absorbable substances (soluble, easily digestible), or immobilized microorganisms protein,…
  • Supply, supplement and promote soil microflora to develop, operate, increase resistance of plants to help limit pests and diseases, reduce the amount of pesticides, thereby improving the quality of products.
  • Eco-friendly and safe for humans and animals.

Classification of Bio-Organic Fertilizers

 

1. Nitrogen-fixing biological organic fertilizer

This fertilizer contains microorganisms that are able to fix nitrogen compounds that are difficult to absorb from the air into a form that is easily absorbed by plants.

There are generally two forms of microorganisms currently living in nitrogen-fixing bio-organic fertilizers:

  • Free form of nitrogen-fixing microorganisms: Capable of fixing nitrogen in the soil without the need for a host such as Clostridium, Azotobacter…
  • The form of symbiotic nitrogen-fixing microorganisms: Capable of fixing nitrogen in the soil but requires a plant host to symbiotically. For example, Rhizobium needs symbiosis with legumes, Anabaena azollae needs symbiosis with green algae or mulberry flowers….

In addition, some bacteria have the ability to both fix nitrogen in a free way and fix nitrogen in a symbiotic way.

2. Phosphate-degrading bio-organic fertilizer

Similar to nitrogen-fixing bio-organic fertilizers, phosphate-degrading bio-organic fertilizers contain microorganisms capable of decomposing phosphorus from a soil-soluble form to a soluble form, making it easy for plants to absorb.

3. Bio-organic fertilizer breaks down potassium and silicon

This fertilizer contains microorganisms with the ability to decompose compounds containing potassium, silicon such as silicates … for the purpose of releasing potassium and silicon in the form of ions, which is a form that plants can absorb.

The potassium and silicon degrading microorganisms used include B. subtilis, Bacillus circulans or Pseudomonas striata…

4. Bio-organic fertilizer that breaks down cellulose organic matter

For this type of fertilizer, microorganisms are capable of decomposing organic compounds, fresh manure or plant residues.

The microorganisms commonly used are Streptomyces, Bacillus or Trichoderma, etc.

5. Bio-organic fertilizers inhibit pathogenic microorganisms

This type of fertilizer has the ability to inhibit microorganisms that are harmful to plants through microorganisms capable of parasitic, antagonistic, countermeasure, natural enemies or secrete substances that inhibit or inhibit the growth of plants. microorganisms that are detrimental to plant growth.

6. Bio-organic fertilizers provide trace mineral nutrition

Is a fertilizer containing the microbial strain Bacillus sp. capable of dissolving Zn, Si… converted into a form that is easily absorbed by plants.

7. Bio-organic fertilizers produce growth stimulants

Using microorganisms such as Pseudomonas, Azotobacter, Gibberella fujikuroi … secrete growth stimulants, creating a favorable environment for plants to absorb and grow well.

Basic Bio-Organic Fertilizer Production Process

 

  1. Determine the type of bio-organic fertilizer to be made, then select the group of microorganisms that need to be cultured for the composting process.
  2. Isolation and selection of microorganisms.
  3. Prepare the necessary materials and select the fermentation option to create a favorable environment for microorganisms to grow and multiply many times.
  4. Create the best fermentation environment for microorganisms to grow quickly and meet the quality of bio-organic fertilizers when put into cultivation and agricultural production.
  5. Proceed to put all raw materials into bio-organic fertilizer production.
  6. After the qualified time, at this time can proceed to exploit and use.

How to Use Bio-Organic Fertilizer Effectively

  • Applicable for both priming and top dressing. Can be used as a base fertilizer or sprayed on leaves. By spreading evenly and then burying when making soil or fertilizing according to the hole, the row is covered with a thin layer of soil before planting, with perennial plants fertilizing in the hole mixed with the top soil layer and then placed in the planting hole created previously.
  • When priming for perennial plants, also apply trenching around the foliage and then cover with a thin layer of soil or spread evenly on the ground and then water it so that the fertilizer can immediately absorb into the soil.
