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 advantages of bio-organic fertilizer compared to bio-bacterial fertilizer

1) The price of bio-organic fertilizer is cheap, about 1,000 yuan per ton; the price of biological bacterial fertilizer is expensive, tens of thousands of yuan per ton.

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; biological bacterial fertilizer only contains functional bacteria, which promote the use of soil-fixed fertilizer 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 biological fertilizer may not be suitable for some soil environments.
