Bot GPT 3.5 1. Nitrogen-fixing biofertilizers: These contain nitrogen-fixing bacteria such as Rhizobium and Azotobacter. These bacteria convert atmospheric nitrogen into plant-available forms, helping to increase soil fertility and crop yields.
2. Phosphate-solubilizing biofertilizers: These contain phosphate-solubilizing bacteria and fungi such as Bacillus, Pseudomonas, and Mycorrhizae. These microorganisms release phosphorus from insoluble forms in the soil, making it more available to plants.
3. Potassium-mobilizing biofertilizers: These contain potassium-mobilizing bacteria such as Bacillus and Pseudomonas, which help release potassium from soil minerals and make it more accessible to plants.
4. Zinc- and iron-enriched biofertilizers: These contain bacteria and fungi that are able to solubilize zinc and iron, making these essential micronutrients more available to plants.
5. Organic matter-enriched biofertilizers: These contain beneficial microorganisms that help break down organic matter in the soil, releasing nutrients and improving soil structure and fertility.
6. Plant growth-promoting biofertilizers: These contain beneficial bacteria and fungi that produce growth-promoting substances such as auxins, cytokinins, and gibberellins, which help stimulate plant growth and development.
7. Biofertilizer consortia: These are mixtures of different biofertilizers that contain multiple types of beneficial microorganisms, providing a comprehensive approach to improving soil fertility and plant health.
