What are the advantages and effects of bio-organic fertilizer?
Bio-organic fertilizer refers to a type of fertilizer that combines specific functional microorganisms with organic materials mainly derived from animal and plant residues (such as livestock and poultry manure, crop straw, etc.) that have undergone harmless treatment and composting, and has the effects of both microbial fertilizer and organic fertilizer.
Bio-organic fertilizer compared with chemical fertilizer
1. Bio-organic fertilizer has a complete range of nutrient elements; chemical fertilizer has only one or a few nutrient elements.
2. Bio-organic fertilizer can improve the soil; frequent use of chemical fertilizer causes soil compaction.
3. Bio-organic fertilizer can improve product quality; excessive application of chemical fertilizer leads to poor product quality.
4. Bio-organic fertilizer can improve the microbial community in the crop rhizosphere and enhance the plant's resistance to pests and diseases; chemical fertilizer leads to a single microbial population in crops, making them prone to pests and diseases.
5. Bio-organic fertilizer can promote the utilization of chemical fertilizer and improve its use efficiency; using chemical fertilizer alone easily causes fixation and loss of nutrients.
Bio-organic fertilizer compared with refined organic fertilizer
Refined organic fertilizer is a commercial organic fertilizer made from livestock and poultry manure that has been dried, crushed and then packaged for sale.
1. Bio-organic fertilizer is fully composted, does not burn roots and does not rot seedlings; refined organic fertilizer is not composted, and after direct use it composts in the soil, causing seedling burn.
2. Bio-organic fertilizer is composted at high temperature, killing most pathogenic bacteria and insect eggs and reducing the occurrence of pests and diseases; refined organic fertilizer is not composted, and when it composts in the soil it attracts underground pests.
3. Bio-organic fertilizer has beneficial bacteria added, and due to the occupancy effect of the bacterial community, disease occurrence is reduced; refined organic fertilizer, due to high-temperature drying, has all its microorganisms killed.
4. Bio-organic fertilizer has a high nutrient content; refined organic fertilizer suffers nutrient loss due to high-temperature treatment.
5. Bio-organic fertilizer has been deodorized, has a mild odor and is almost odorless; refined organic fertilizer has not been deodorized and gives off a foul odor as soon as it absorbs moisture.
The difference between bio-organic fertilizer and farmyard manure
1. Bio-organic fertilizer is fully composted, and the insect egg mortality rate reaches more than 95%; farmyard manure is simply piled up, and the insect egg mortality rate is low.
2. Bio-organic fertilizer is odorless; farmyard manure has a foul odor.
3. Bio-organic fertilizer is convenient and uniform to apply; farmyard manure is inconvenient to apply, and the fertilizer application is uneven.
The difference between bio-organic fertilizer and microbial bacterial fertilizer
1. Bio-organic fertilizer is cheap, at around more than 1000 yuan per ton; microbial bacterial fertilizer is expensive, at over 10,000 yuan per ton.
2. Bio-organic fertilizer contains functional bacteria and organic matter, can improve the soil and promote the release of nutrients fixed by the soil; microbial bacterial fertilizer contains only functional bacteria, and uses functional bacteria to promote the utilization of fertilizer fixed by the soil.
3. The organic matter in bio-organic fertilizer is itself the living environment for functional bacteria, so they easily survive after being applied to the soil; while the functional bacteria in microbial bacterial fertilizer may not be suitable for some soil environments.
