Organic fertilizer is the "basic" or "standard" version, primarily providing organic matter and nutrients.

Bio-organic fertilizer is an "upgraded" or "functional" version. It not only adds beneficial microorganisms to organic fertilizer, but also makes these microorganisms the "main force" in improving soil quality and promoting growth.

1. Similarities

They are all fertilizers based on organic matter and share many common advantages:

1. The same source of raw materials: Both primarily originate from animal and plant residues (such as straw, livestock and poultry manure, kitchen waste, agricultural product processing scraps, etc.), which are processed to form the final product.

2. Rich in organic matter: The core component is organic matter, which is the key to improving the physical structure (granular structure) of soil and enhancing its water and nutrient retention capacity.

3. Comprehensive nutrition: Both contain a large amount of macronutrients such as nitrogen, phosphorus, and potassium, as well as various trace elements, providing comprehensive nutrients but releasing slowly.

4. Environmentally friendly: It can reduce the use of chemical fertilizers, mitigate non-point source pollution, and achieve resource utilization of agricultural waste.

II. Differences

The fundamental difference between them lies in the word "biological", which refers to whether they contain a specific and effective number of functional microorganisms.

Characteristics: Organic Fertilizer, Bio-organic Fertilizer

Core Definition: A fertilizer primarily derived from the residues of animals and plants, produced through composting and fermentation, and rich in organic matter. This fertilizer, using organic matter as its carrier, incorporates specific functional microorganisms, offering both organic and microbial effects.

Core components: organic matter + nutrients; organic matter + nutrients + specific functional microbial strains

Main functions: 1. Providing nutrients (slow-release) 2. Improving soil quality (enhancing fertility) 3. Enhancing soil physical structure. 1. Possessing all the functions of organic fertilizers. 2. Special microbial functions of phosphorus and potassium release: releasing fixed nutrients from the soil

Nitrogen fixation: The process of converting nitrogen from the air into nitrogen compounds that can be absorbed by plants.

Antagonistic pathogens: inhibit soil-borne diseases.

- Producing growth-promoting substances: Secreting growth hormones, vitamins, etc. to promote crop growth.

- Decompose toxic and harmful substances: degrade pesticide residues, heavy metals, etc.

Production process: Composting and fermentation (the main process), aimed at eliminating pathogens, insect eggs, and weed seeds, and stabilizing organic matter. Composting and fermentation + microbial addition. First produce qualified organic fertilizer, and then mix in specific functional microbial inoculants in the later process.

Function and Effect The effect is relatively single and slow, mainly reflected in providing basic fertility and improving soil physical properties. The effect is more comprehensive, rapid, and "intelligent". Microorganisms can actively mobilize soil potential to solve specific soil problems (such as compaction and disease).

Technical standards primarily focus on physical and chemical indicators such as organic matter content, nutrient content, moisture, and pH value. In addition to meeting all the standards for organic fertilizers, the core indicator is the effective viable bacterial count. For example, the standard (NY/T 884-2012) requires that the effective viable bacterial count be no less than 20 million per gram.
