The role of bio-organic fertilizers Bio-organic fertilizers have different functions due to the different types of microorganisms contained. In summary, they have the following effects.
⑴ Nitrogen fixation, such as root nodules and nitrogen-fixing bacteria, they can fix nitrogen in the air under suitable environmental conditions and provide nitrogen nutrition for crop growth. It is estimated that the annual biological fixation of nitrogen by crops can reach 101 million tons.
⑵Nutrient release effect Microorganisms decompose some substances in the soil that are difficult to be absorbed and utilized by crops and convert them into effective nutrients that can be absorbed and utilized by crops. For example, silicate bacteria can not only decompose difficult-to-decompose minerals such as potassium feldspar and mica in the soil, and release the fixed potassium, but also promote the conversion of insoluble phosphorus in the soil into a form that can be used by crops.
⑶ Growth-promoting effect After applying microbial fertilizer to the soil, it not only increases the nutrient content in the soil, but also promotes the synthesis of various vitamins, enzymes and other substances beneficial to crop growth, stimulates the growth of crops, and assists crops in absorbing nutrients. In the fertilizer production process, the addition of biological agents is before the fertilizer packaging.
⑷Disease resistance After some microorganisms are inoculated in the soil, they multiply in the roots of crops and become the dominant bacteria in the rhizosphere of the crops for a period of time, inhibiting or reducing the reproduction opportunities of pathogenic microorganisms, and some microorganisms will also have resistance to pathogenic microorganisms. Although microbial fertilizer can provide nutrients for crop growth and stimulate and promote crop growth, its role is still limited after all. In crop production, organic fertilizers and chemical fertilizers are mainly used to provide nutrients for crop growth. According to the different organic fertilizer materials, the selected organic fertilizer granulator is also different.
⑸Many raw materials in nature contain many beneficial microorganisms, but once these raw materials are applied to the soil, the microorganisms in them will be eaten by countless microorganisms in the soil. Therefore, it cannot survive stably in the soil, and its effect is difficult to show. However, if the beneficial bacteria are added to the fermented organic fertilizer after fermentation, the fermented organic fertilizer itself is the expansion medium, which will cause the bacteria to proliferate in large numbers. At this time, applying microbial organic fertilizer to the soil will quickly form a dominant population in the soil, which can play a good role in the root system of the crop. Fermented organic fertilizer has a good effect on exerting microbial activity. Welcome to buy our company’s organic fertilizer machine.
