Biofertilizer- Types and Uses

Biofertilizer is a substance which contains living microorganisms which, when applied to seeds, plant surfaces, or soil and promotes growth by increasing the supply or availability of primary nutrients to the host plant.

  • Biofertilizers add nutrients through the natural processes of nitrogen fixation, solubilizing phosphorus, and stimulating plant growth through the synthesis of growth-promoting substances.

Types of biofertilizers

  1. Nitrogen-fixing biofertilizers
  2. Phosphorus fixing biofertilizers

Benefits of Biofertilizers

  • It helps in maintaining environmental health by reducing the level of pollution.
  • Reduces human & animal hazards by reducing the level of residue in the product.
  • Increases the agricultural products and makes it sustainable
  • Ensures the optimum utilization of natural resources.
  • Reduces the risk of crop failure.
  • Improves the physical and chemical properties of soil
  • Biofertilizers are cost-effective when compared to synthetic fertilizers
  • Using biofertilizers can increase crop yield by 20 or 30 percent.

Uses of Biofertilizer

  1. Nitrogen-fixing biofertilizers

Cultivated crop determine what type of nitrogen biofertilizer should be used:

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

2. Phosphorus fixing biofertilizers

Phosphorus biofertilizers are not dependent on the crops cultivated on the soil:

  • Phosphatika for all crops to be applied with
  • Rhizobium
  • Azotobacter
  • Azospirillum and Acetobacter

Compost fixing biofertilizers

Biofertilizers can use to enrich your compost and the bacterial processes breaking down the compost waste

  •  Phosphotika and Azotobacter culture.

Drawbacks of Biofertilizers

  • Slow-release
  • Crop specific
  • Strain-specific
  • Soil specific—lose effectiveness if soil too dry or hot
  • Lesser efficient than synthetic fertilizers
  • Crops show less response to biofertilizers then chemical fertilizers
  • Much lower nutrient density — requires large amounts to get enough for most crops.
