Organic-inorganic compound fertilizer is a kind of compound fertilizer which contains both organic matter and chemical fertilizer. It is a kind of organic material, such as feces and peat, which is treated harmlessly and effectively by microbial fermentation, and is added with appropriate amount of fertilizer, humic acid, amino acid, etc. through granulation or direct mixing.
Organic fertilizer refers to slow-acting fertilizer formed after fermentation and decomposition of animal and plant residues, excreta and biological waste. The main component of organic fertilizer is organic matter. After being applied to the soil, it can be decomposed by microorganisms and continuously release various nutrients for plant absorption. It can provide comprehensive nutrients for crops with long fertilizer efficiency. Organic fertilizer is the main substance for improving soil. It can enhance the ability of soil water and fertilizer conservation, increase plant yield and improve quality. It is the main nutrient for green food production.
Bio-organic fertilizer is a kind of fertilizer which is compounded by adding special functional microorganisms into organic fertilizer. The function of bio-organic fertilizer is to increase soil nutrients and soil biological activity. Bio-organic fertilizer contains functional bacteria and organic matter, which can improve the soil and promote the release of nutrients fixed by the soil.
All of them are rich in organic matter, which can improve soil structure and increase soil nutrients.
Organic-inorganic compound fertilizers and organic fertilizers all contain a certain amount of nitrogen, phosphorus and potassium nutrients. Bio-organic fertilizers generally do not contain NPK.
Organic-inorganic compound fertilizer: Organic matter content in organic-inorganic compound fertilizer is not less than 20%, total NPK content is not less than 15%.
Organic fertilizer: Organic matter content in organic fertilizer is not less than 30%, total NPK is not less than 4%, not more than 15%.
Bio-organic fertilizer: The organic matter content in bio-organic fertilizer is not less than 25%, and the number of effective living bacteria is more than or equal to 0.2 billion/g.
Organic-inorganic compound fertilizer: less than 200 kg per mu sown.
Organic fertilizer: low nitrogen content, sown per mu up to 500 kg.
Bio-organic fertilizer: less than 100 kg per mu sown.
Granulator is an important equipment for making fertilizer. New type organic fertilizer granulator, disc granulator and drum granulator can be used in organic fertilizer production line and bio-organic fertilizer production line. Two-in-one organic fertilizer granulator can be used in organic-inorganic compound fertilizer production line.
