Bio-fertilizers add kg N/ha in soil and enhance crop production and nutrient use efficiency  · This chapter highlights the types, quality control measures, inoculation techniques of microbial biofertilizers; their role in sustaining agricultural productionand challenges as  · Download chapter PDFIntroduction. Biofertilizers used in organic agriculture are classified into different types on the basis of group of microorganisms they 1 Microbial Biofertilizers: Types and Applicationsthat, by functioning as an extended root system, harvest moisture and variousmicronutrients from deeper and distant niches in the soil Biofertilizers supplement synthetic fertilizers and fulfil the nutrient requirement of crops. The most commonly used biofertilizers are nitrogen-fixers (N-fixers), potassium solubilizers (K solubilizers), phosphorus solubilizers (P solubilizer), and plant growth-promoting rhizobacteria (PGPR) Biofertilizers includes one or more beneficial microbes that facilitate better nutrient uptake, greater production of growth hormone and beneficial phytochemicals in crops leading to higher Biofertilizers are divided into groups based on their functions and mechanisms of action. Biofertilizers supplement synthetic fertilizers and fulfil the nutrient requirement of crops. These problems can be tackled by use of biofertilizers and biopesticides, which are natural, beneficial, and ecologically and user-friendly Types of Biofertilizers. Fertilizers are natural or man-made chemicals that, when applied on the plant or to soil or by fertigation (applying by irrigation Types of biofertilizers (on the bases of nature and function)Nitrogen fixing: Nitrogen is most abundant and ubiquitous in the air, yet becomes a limiting nutrient due to difficulty of its  · Types of biofertilizers and their working principles. They efficiently reduce use of synthetic fertilizers and create chemical free yield The excessive use of chemical fertilizers and pesticides has generated several environmental problems including the greenhouse effect, ozone layer depletion, and acidification of water. Bio-fertilizers add kg N/ha in soil and enhance crop production and nutrient use efficiency in a particular optimum environment.
