A form of fertilizer used in agricultural production is called a microbial fertilizer, which harnesses the living activity of microorganisms to provide crops with a particular fertilizing impact. Microbial fertilizers are crucial to agriculture because they increase crop growth, disease resistance, and resilience in addition to increasing soil nutrient availability. The way that microbial fertilizers work Following the application of microbial fertilizers to the soil, a variety of processes will take place among the crops, species, and soil ecology to guarantee the crop’s stable growth and yield increase, including nutrient coordination, biological nitrogen fixation, and coexistence and coprosperity between bacteria and crops. Boost soil fertility and optimize fertilizer use In addition to providing a certain amount of quick-acting nitrogen, phosphorus, potassium, and trace elements along with comprehensive nutrients, microbial fertilizers are rich in organic matter and increase soil fertility. The combined action of several high-efficiency strains of beneficial microbial flora also increases soil porosity and improves the rate at which nitrogen, phosphorus, and potassium in conventional fertilizers are utilised. For instance, bacteria can progressively degrade organophosphorus compounds, apatite, and tricalcium phosphate, generating phosphorus pentoxide that plants can absorb and utilize again. enhancing the granular structure of the soil and allowing it to loosen During development and reproduction, microorganisms generate copious amounts of extracellular polysaccharides. The binders that create and maintain the structure of soil glomeruli are called extracellular polysaccharides. The stability of aggregates in the soil between a crop’s roots is related to bacteria that produce polysaccharides around the root system. Furthermore, the organic matter present in microbial fertilizers can raise the soil’s organic matter content, strengthen its structure, deactivate the soil less, lessen clumping, and increase its capacity to hold onto water, fertilizer, and air permeability. Encourage the growth and resilience of crops During the fermentation process and living activity in the soil, microorganisms are able to produce enormous amounts of compounds that resemble phytohormones, such as erythromycin and cytokinin. These substances, when in touch with the crop root system, stimulate crop development and control crop metabolism.Microbial fertilizers control crop stomata opening by the addition of organic matter and humic acid. These nutrients combine with the metabolites (enzymes) of helpful microbes to increase crop resilience. decrease in soil-borne illnesses Microorganisms grow and multiply in large numbers in the crop root system after microbial fertilizer is applied. These microorganisms form the dominant bacteria between the crop roots and, through a combination of competition, parasitism, occupancy, and other relationships, inhibit and reduce the chance of pathogenic bacteria reproducing. Certain microorganisms can also produce active substances such as lysozyme and antibiotics, which effectively inhibit the growth of pathogenic bacteria in the soil and contribute to the reduction of soil-borne agricultural diseases. Decomposition of soil residues of toxic substances Beneficial microbial populations can suppress the growth and reproduction of pathogenic bacteria, break down pesticide and fertilizer residues in the soil, break down toxic inter-root secretions that have accumulated there, and lessen crop crop disruption. Typical microbial fertilizer strains A total of 2,789 (including 936 liquid) microbial agent product registration certificates are held by the Ministry of Agriculture and Rural Affairs. Out of all the bacteria species registered, about 152 are used frequently in the development of national standards. The most commonly used species are Bacillus subtilis, jelly-like Bacillus subtilis, Bacillus licheniformis, Bacillus macrocephalus, Bacillus amylophilus, brewer’s yeast, Bacillus subtilis, Streptomyces falciparum, Lactobacillus plantarum, and Aspergillus niger, of which Bacillus subtilis accounts for 75%. As of right now, probiotics, mycorrhizal fungicides, granular type, rhizobial fungicides, nitrogen-fixing fungicides, phosphate fungicides, silicate fungicides, photosynthetic bacterial fungicides, organic material decay agents, probiotics, and mycorrhizal fungicides are the different categories of microbial fungicides that are currently being promoted on the market. The dosage forms of these agents range from liquid-based to powdered and granular. subtilis Bacillus an organism that belongs to the Gram-positive Bacillus genus. Pathogenic bacteria and Bacillus subtilis are in a competitive interaction that involves both spatial site rivalry and nutritional competition. In terms of spatial site competition, Bacillus subtilis has an advantage because of its quick and widespread reproduction and colonization in the soil, which effectively inhibits the growth of pathogenic microorganisms, hinders plant pathogenic microorganisms from invading plants, and disrupts pathogenic microorganisms’ attempts to colonize plants. All of these actions result in the control of fungi and diseases. Bacillus subtilis possesses a lysophilic action; it adheres to the pathogenic fungus’s mycelium and co-proliferates with it, generating lysophilic material that causes the mycelium to break down. Phospholipids, aminosaccharides, peptides, and lipopeptides are examples of antimicrobial compounds produced by Bacillus subtilis that resemble antibiotics and prevent the growth of bacteria, viruses, fungus, and other pathogens. Of them, Bacillus subtilis lipopeptide antibiotics are the most significant antibacterial agents. Amyloliquefaciens Bacillus It is a type of bacteria that has a strong attraction for the safe strain of Gram-positive Bacillus amyloliquefaciens, which poses no threat to humans or animals. It is motile, able to create endogenous budding spores, and during growth releases a variety of antimicrobial compounds. Bacillus amylophilus is commonly found between plant roots in soil, leaves, and fruits in the natural world. Antibacterial proteins (natural antibiotics), peptides, lipopeptides, and polyketides are the principal antimicrobial compounds secreted by Bacillus amylophilus. By competing for ecological niches and fostering systemic resistance, Bacillus subtilis can also inhibit a wide range of dangerous microorganisms. Licheniform Bacillus an organism that belongs to the Gram-positive Bacillus genus. To enable plants to efficiently absorb the nutrients in the soil, Bacillus licheniformis will grow quickly in the soil, take up space, and secrete enzymes such as lipase, amylase, cellulase, and protease. It will also aid in the breakdown of field straw, bran, and other materials. Bacillus licheniformis is frequently employed in agricultural production because it can create anti-active compounds such as humic acids, amino acids, and nucleic acids. It also has a substantial inhibitory effect on a variety of plants, animals, and human infections. Mucilaginosus Bacillus It is often referred to as silicate bacteria and is a common soil bacterium found in agricultural areas because of its ability to dissolve insoluble potassium in minerals that contain potassium for crop usage. Jelly-like microorganism The traits of Bacillus mucilaginosus are robust vitality, quick reproduction, safety, and non-toxicity. Bacillus jelly-like can significantly increase fertilizer use and decrease fertilizer use by breaking down phosphorus, potassium, and nitrogen fixation. Polymyxa paenibacillus A budding Gram-positive bacteria with an aerobic or parthenogenic anaerobic life cycle is Bacillus pallidum, genus Bacillus subsp. According to its structural makeup, Paenibacillus polymyxa can synthesize a wide range of metabolically active substances, which can be classified as peptides, proteins, polysaccharides, etc. These substances can be used for biological nitrogen fixation, phosphorus dissolution, potassium reduction, antagonistic microorganisms, plant growth promotion, and other purposes. When used as a microbial fertilizer on plants, it immediately becomes incorporated into the internal and inter-root structures of the plant, where it produces a biofilm that facilitates the plant’s uptake of nutrients. The benefits and drawbacks of microbial fertilizers Microbial fertilizers are widely available in the market. Based on real-world use, a high-quality microbial fertilizer may successfully minimize soil-borne illnesses, alleviate crop stubble, improve soil grain structure, and increase plant resilience. A good microbial fertilizer should simultaneously possess many of the following qualities at the root. outstanding strains After repeated field verification, microbial fertilizer strains should be used in the lab for screening, identification (both physical and chemical), mechanism of action, and characteristics of a clearer basis to demonstrate that the excellent strains have a good fertilization effect and meet production requirements. Optimization of the production process Selecting the appropriate equipment for fermentation will stop contamination before it starts. The composition of the medium, pH, temperature, ventilation, sorbent selection, and sterilization should all be done in a way that respects the needs of the species. excellent purity of the strain and few impurities It appears that the more effective live bacteria there are, the greater the benefit; however, this is not totally true. Only living bacteria remain after the application of microbial fertilizer, and these bacteria are quantified using the effective live bacteria standard. A few subpar products on the market contain pathogenic bacteria, which not only cannot repair the soil but also cause disease. The purity of the strain is crucial when the product contains mold contaminants and the contaminant rate exceeds the standard. inter-strain synergies More strains and greater numbers are not the goal of microbial fertilizers. Because it is so simple to create strain antagonism, the development habits of the various strains of compound microbiological bacteria will have an impact on the outcome of using them. Therefore, the ability of the strains to work in concert and support one another to produce the optimal outcomes is more important than the number of strains in the combination. Using microbial fertilizers in a sensible way Fertilizers containing bacteria shouldn’t be combined with microbial fertilizers. In theory, fungicides can be combined with microbial fertilizers and bacterial fertilizers, but in actuality, this will lessen the activity of the strains. Furthermore, the strain’s activity may be impacted by the fertilizer’s high salt ion concentration. Therefore, combining microbial fertilizers with fungicides or other fertilizers is not advised. Microorganisms require specific temperature, moisture, and environmental conditions to develop; high temperatures and dry environments should be avoided. In hot and dry climates, reproduction is hindered and survival is jeopardized. To ensure that micro fertilizers are effective, this kind of fertilizer should be applied in the evening on a cloudy or sunny day and paired with soil cover, manure cover, watering, etc. to prevent direct sunlight or a lack of moisture. Although microbial fertilizers can increase fertilizer usage and decrease fertilizer inputs, they cannot completely replace chemical fertilizers. The use of microbial fertilizers can increase the biological fertility of the soil, which can afterwards encourage an improvement in chemical and physical fertility. This is because soil fertility is comprised of three components: biological, chemical, and physical fertility. top provider of microorganism fertilizer for environmentally friendly farming Related Articles: Fertilizer, Microbial Send a Friend an Article via Email!Get articles like this one sent straight to your inbox!Register now for free!â
