Bio-organic fertilizer refers to the fertilizer that is processed through microbial fermentation, decomposing and harmless treatment by using livestock and poultry manure, straw, agricultural and sideline products and waste from food processing, organic garbage, and urban sludge.

1 Compared with chemical fertilizer:

1) Bio-organic fertilizer has complete nutrient elements; chemical fertilizer has only one or several nutrient elements.

2) Bio-organic fertilizer can improve the soil; regular use of chemical fertilizers can cause soil compaction.

3) Bio-organic fertilizer can improve product quality; excessive application of chemical fertilizers leads to poor product quality.

4) Bio-organic fertilizer can improve the rhizosphere microbiota of crops and increase the resistance of plants to diseases and insects; chemical fertilizers have a single crop microbial population and are prone to pests and diseases.

5) Bio-organic fertilizer can promote the use of chemical fertilizers and increase the utilization rate of chemical fertilizers; the use of chemical fertilizers alone can easily cause nutrient fixation and loss.

2 Compared with refined organic fertilizer:

Refined organic fertilizer is a commercial organic fertilizer that is packaged and sold after drying and crushing livestock manure.

1) Bio-organic fertilizer is completely decomposed, does not burn roots, and does not rot; refined organic fertilizer is not decomposed, and it will decompose in the soil after direct use, which will cause the phenomenon of burning seedlings.

2) Bio-organic fertilizer decomposes under high temperature, which kills most pathogenic bacteria and insect eggs and reduces the occurrence of pests; refined organic fertilizer is not decomposed and will attract underground pests when it decomposes in the soil.

3) Beneficial bacteria are added to the bio-organic fertilizer, which reduces the occurrence of diseases due to the occupying effect of the flora; the refined organic fertilizer does not contain beneficial bacteria 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 has a light smell and is almost odorless after deodorization; if the refined organic fertilizer is not deodorized, the odor will appear when the moisture returns.

3 The difference between bio-organic fertilizer and farmyard manure:

1) Bio-organic fertilizer is completely decomposed, and the mortality rate of insect eggs reaches more than 95%; the pile of farmyard manure is simple, and the mortality rate of insect eggs is low.

2) Bio-organic fertilizer is odorless; farmyard manure has a foul smell.

3) The application of bio-organic fertilizer is convenient and uniform; the application of farmyard manure is inconvenient and the application of fertilizer is uneven.

4 The difference between biological organic fertilizer and biological bacterial fertilizer:

1) The price of bio-organic fertilizer is cheap, about 1,000 yuan per ton; the price of bio-organic fertilizer is expensive, the price is as high as 10,000 yuan.

2) Bio-organic fertilizer contains functional bacteria and organic matter, which can improve the soil and promote the release of nutrients fixed by the soil; bio-organic fertilizer contains only functional bacteria, which promote the use of soil fixed fertilizers through functional bacteria.

3) The organic matter of bio-organic fertilizer itself is the living environment of functional bacteria, and it is easy to survive after being applied to the soil; while the functional bacteria of bio-organic fertilizer may not be suitable for some soil environments.
