BioFertilizer

Ans: With the introduction of green revolution technologies the modern agriculture is getting more and more dependent upon the steady supply of synthetic inputs (mainly fertilizers), which are products of fossil fuel (coal+ petroleum). class=jfy1>Adverse effects are being noticed due to the excessive and imbalanced use of these synthetic inputs. This situation has lead to identifying harmless inputs like biofertilizers. Use of such natural products like biofertilizers in crop cultivation will help in safeguarding the soil health and also the quality of crop products.

Ans.:

For Nitrogen

• Rhizobium for legume crops.
• Azotobacter/Azospirillum for non legume crops.
• Acetobacter for sugarcane only.
• Blue –Green Algae (BGA) and Azolla for low land paddy.

For Phosphorous

• Phosphate solubilizing  Biofertilizer

For Potassium

• Mobilizing Biofertilizers

Ans:

• Biofertilizer need to be stored in cool and dry place away from direct sunlight and heat.
• As Rhizobium is crop specific, one should use for the specified crop only.
• Other chemicals should not be mixed with the biofertilizers.
• Biofertilizer has to be used before its expiry.
• While using it soil moisture is essential.
• Seed treatment with fungicide /insecticide should be followed by Biofertilizers

Ans: Anybody who is involved in farming can use these biofertilizers in crops such as legumes, cash crops, cereal crops, fodder crops, oil seed crops, horticultural crops, vegetables, fruit trees.

Ans: There is a huge difference in the application amount and the actual availability of chemical fertilizers to the plants. Biofertilizers have been reported to enhance the availability of these inorganic inputs to the plants. Thus Biofertilizers can be used along with chemical fertilizers but the care should be taken to avoid direct contact of chemical based inputs with Biofertilizers which is likely to reduce the microbial population of Biofertilizers.

Ans:

• Cost effective.
• Supplement to fertilizers.
• Eco-friendly (Friendly with nature).
• Reduces the costs towards fertilizers use, especially regarding nitrogen and phosphorus.

Ans: Chemical fertilizers are manufactured artificially. They are primarily, chemicals having nitrogen, phosphate and potash as main soil nutrients. Bio-fertilizers are plants such as bacteria (azotobacter, rhizobium etc.), fungi etc. that fix free nitrogen from the atmosphere, which is then 'used by the crops.
