What is liquid Biofertilizer?
Liquid biofertilizers are the microbial preparations containing specific beneficial microorganisms which are capable of fixing or solubilizing or mobilizing plant nutrients by their biological activity [2].
What are the advantages to producing biofertilizers?
Biofertilizers restore normal fertility to the soil and make it biologically alive. They boost the amount of organic matter and improve soil texture and structure. The enhanced soil holds water better than before. Biofertilizers add valuable nutrients to the soil, especially nitrogen, proteins and vitamins.
How do you use liquid Biofertilizer?
The biofertilizer is applied at the rate of 100gm per 5Kg of seeds. The per acre application rate is determined from the amount of seed to be sown in a field. Before the application, biofertilizer is mixed in water (1:2) to form slurry. The slurry is poured in container with seeds to be sown.
What are the benefits of using an algae based Biofertilizer?
The algae-based wastewater remediation for bio-fertilizer production shows great advantages: (1) Wastewater could be obtained at very low cost, reducing the selling prices of algal bio-fertilizer; (2) The algae-based wastewater remediation could convert waste nutrients to value-added biomass, creating economic benefits …
Why should we use biofertilizer?
Biofertilizers add nutrients through the natural processes of nitrogen fixation, solubilizing phosphorus, and stimulating plant growth through the synthesis of growth-promoting substances. Through the use of biofertilizers, healthy plants can be grown, while enhancing the sustainability and the health of the soil.
What are biofertilizers give examples?
There are five biofertilizers viz. Rhizobium, Azotobacter, Azospirillum, Phosphate Solubilizing Bacteria and mycorrhiza , which have been incorporated in India’s Fertilizer Control Order (FCO), 1985. Rhizobium, Azotobacter, Azospirillum and blue green algae(BGA) have been traditionally used as Biofertilizers.
What are the disadvantages of biofertilizers?
The disadvantages of biofertilizers
- Biofertilizers provide lower nutrient density than chemical fertilizers, so more product is often required for the same effect.
- Biofertilizer production requires specific machinery.
- Biofertilizers can be difficult to store and may have a much shorter shelf-life than chemical fertilizers.
What are the three benefits of biofertilizers?
Low cost and can be used by marginal farmers. Free from pollution hazards. Increase soil fertility.
How are biofertilizers treated?
Application of biofertilizers to crops The seeds required for one hectre are mixed in the slurry so as to have uniform coating of the inoculants over the seeds and then shade dried for 30 minutes. The treated seeds should be used within 24 hous. One packet of inoculant is sufficient to treat to 10 kg seeds.
What are the uses of biofertilizers?
Biofertilizers are considered as a feasible and sustainable attractive biotechnological alternative to increase crop yield, improve and restore soil fertility, stimulate plant growth, reduce production costs and the environmental impact associated with chemical fertilization [12, 13, 14].
Which algae is used as biofertilizer example?
Blue-green algae is used as a biofertilizer.
What is cyanobacterial biofertilizer?
Cyanobacteria have an emerged potential as biofertilizer. They have the ability to utilize CO2, water, and nutrients to convert solar energy into biomass. Efficient applications of cyanobacteria have been reported in agricultural practices to reduce global warming by decreasing CO2 gas.
What are the advantages of using biofertilizer in agriculture?
There are many advantages of Biofertilizer in agriculture crops, let us get into details of Biofertilizer advantages and different types of Biofertilizer. This group fixes nitrogen symbiotically. Nitrogen biofertilizers help to accurate the nitrogen levels in the soil.
What do microbes do in a biofertilizer?
Microbes in biofertilizers provide atmospheric nitrogen directly to plants. They aid in solubilisation and mineralisation of other plant nutrients like phosphates.
Why is Azolla a good biofertilizer for agriculture?
Azolla is a Biofertilizer plant of high importance in agriculture; it supplies Nitrogen for crop growth and a rich source of protein in livestock feed. Read: Snail Farming Techniques.
How does the efficiency of microbial fertilizer vary?
Efficiency of microbial fertilizer depends on soil character, such as, moisture content, pH, temperature, organic matter and types of micro-organisms present. When these factors are unfavourable microbial fertilizer may not be effective in enhancing the soil fertility.
