What is bio-organic fertilizer?

What is bio-organic fertilizer? What are the characteristics of bio-organic fertilizer? Please also ask netizens who know to help introduce bio-organic fertilizer, which generally refers to the use of livestock and poultry manure or crop straw as the main raw materials, the use of biochemical technology and microtechnology, completely kill the pathogenic bacteria, parasitic eggs and other harmful substances contained in the raw materials and eliminate the stench, and then inoculate the microbial compound bacteria to decompose the organic matter in the raw materials, thus forming biological organic fertilizers. Bio-organic fertilizer is the first choice for growing organic crops, so the farming network collates the main role of bio-organic fertilizer, which is listed below for netizens' reference. Bio-organic fertilizer can improve soil structure: bio-organic fertilizer can promote the formation of soil aggregate structure, improve soil physical properties, and enhance soil ventilation and water permeability. at the same time, it can also improve the soil consolidation caused by the use of chemical fertilizer. The second function of bio-organic fertilizer is to increase soil nutrients: bio-organic fertilizer contains a large amount of organic matter adsorbed to nutrients, so that soil nutrients are not easy to lose; and bio-organic fertilizer contains complete nutrients, which are easy to be decomposed and absorbed by crops. and bio-organic fertilizer also contains a certain amount of medium and trace elements such as zinc, manganese, iron and so on. Third, bio-organic fertilizer can improve the transformation of nutrients in soil: after the application of bio-organic fertilizer, under the action of microorganisms, fertilizer organic nutrients can be continuously transformed into effective nutrients that plants can absorb and utilize. at the same time, it can also release some fixed nutrients in the soil. Microorganisms decompose phosphorus-containing compounds to release fixed phosphorus in the soil. Silicate bacteria can improve the activity of potassium in the soil, and microorganisms can also fix easily lost nutrients in the soil. Fourth, bio-organic fertilizer can improve crop yield and quality: vitamins, humic acid and hormones produced by microbial decomposition and transformation of bio-organic fertilizer can stimulate the vigorous growth of crop roots and improve the absorption capacity of crops to phosphorus and potassium; at the same time, it can also increase crop photosynthesis, so that crop roots are developed, ear rate is high, thus increasing yield. At the same time, bio-organic fertilizer contains a variety of organic nutrients, such as amino acids, sugars, nucleic acid decomposition, etc., as well as a large number of microorganisms and enzymes, which play a special role in improving the quality of agricultural products and maintaining their nutritional flavor. The effect of bio-organic fertilizer can increase the ability of drought, cold and disease resistance of crops: the application of bio-organic fertilizer can increase the capacity of soil water storage and water retention, reduce water evaporation and improve the effect of soil moisture, so as to improve the ability of drought and cold resistance of crops. Bio-organic fertilizer has a full range of nutrients, coordinated supply of major elements and trace elements during crop and growth, and avoided crop diseases caused by lack of elements, such as black spot caused by potassium deficiency in potatoes.
