How to use biological organic fertilizer?

Biological organic fertilizer is a new type of organic fertilizer that has appeared in recent years. Compared with traditional organic fertilizer, it has better application effect. However, many people do not know how to use this fertilizer . So how to use biological organic fertilizer specifically? Let’s learn more about it below.

How to use biological organic fertilizer?

1. Seeding and fertilization: When sowing by machine, mix the granular biological organic fertilizer with a small amount of chemical fertilizer and apply it into the soil with the seeder .

2. Broadcasting: When combining deep plowing or sowing, spread the bio-organic fertilizer evenly over the root distribution area, keep it moist, and ensure that the soil and fertilizer blend well.

3. Strip fertilization: For row-sown crops or fruit trees such as grapes, fertilize and sow after digging furrows or dig furrows 5 cm away from the fruit trees to apply fertilizer.

4. Annular trench fertilization: For young fruit trees such as apple, peach, and pear, dig a circular trench around the trunk 20-30 cm away from the trunk and cover with soil after fertilization.

5. Radial trench fertilization: For mature fruit trees such as apple, peach, and pear, dig 4-5 50cm long trenches around the tree 30cm away from the trunk according to the extension of the fruit tree's root system, and cover with soil after fertilization.

6. Hole-fertilization: For spot-seeding or transplanting crops, such as corn, cotton, tomatoes , etc., apply fertilizer into the sowing holes and then sow or transplant.

7. Dip the roots: For transplanted crops, such as rice, tomatoes, etc., add five parts of biological organic fertilizer to water to make a fertilizer suspension, dip the roots of the seedlings, and then plant them.

8. Seed covering fertilizer: After trenching and sowing, evenly cover the seeds with biological organic fertilizer.

Precautions for using biological organic fertilizer

1. The soil moisture content should not be too high when applying. The activity of biological agents is greatly affected by moisture, especially when they are just applied to the soil. An unsuitable moisture range has a certain impact on the reproduction and activity of microorganisms. It is recommended that the soil moisture content be controlled below 65% when using biological organic fertilizer.

2. It is not recommended to mix with chemical fertilizers. Fertilizers include neutral, acidic and alkaline fertilizers. The weakly alkaline environment formed after the dissolution of alkaline fertilizer has a certain inhibitory effect on the reproduction and activity of microorganisms, and also has a certain inhibitory effect on the decomposition and nutrient release of organic fertilizers. Moreover, the high-salinity aqueous solution environment formed by fertilizers also has certain adverse effects on microorganisms.

3. It needs to be applied annually. The microbial components in biological organic fertilizers need to be used year after year to ensure the number of soil microorganisms.

4. The application effect in alkaline soil is poor. Whether it is microorganisms or organic fertilizers, their functions will be significantly inhibited in alkaline soil.

5. It is not suitable to use biological organic fertilizer in soil with high sulfur content, because sulfur can kill microorganisms.

6. Avoid using biological organic fertilizers together with pesticides, as chemical pesticides will inhibit the growth and reproduction of microorganisms, or even kill them.
