Bio-fertilizers are substances which contain living microorganisms. When bio-fertilizers are applied to seeds or soil, they promote the growth of the plant by increasing plant nutrients.
Azotobacter, Rhizobium, Azospirillum, Phosphate solubilizing bacteria, and Mycorrhizal fungi are some examples of bio-fertilizers used to enhance soil fertility and plant growth.
Bio-intensive agriculture is a farming approach that focuses on maximizing crop yields while minimizing the use of external inputs such as fertilizers and pesticides. It emphasizes sustainable practices like crop rotation, composting, and intercropping to enhance soil fertility and biodiversity. This method aims to promote self-sufficiency and reduce the impact of agriculture on the environment.

The two fertilizers in Group 5A are ammonium nitrate and ammonium sulfate.
The difference is that chemical fertilizers have chemicals. And bio fertilizers don't.

Attention to the amount and the placement of bio fertilizers as well as to related cultivating efforts are precautions to be taken while using bio fertilizers.Specifically, bio fertilizers are nitrogen fixing bacteria and phosphate solubilizing bacteria and fungi. Nitrogen fixing bacteria absolutely must be placed near the roots in order to be able to pursue their symbiotic relationship with the plant. Bio fertilizers need healthy, well-drained soils with adequate levels of air, microorganic life, moisture and nutrients.
Azotobacter, Rhizobium, Azospirillum, Phosphate solubilizing bacteria, and Mycorrhizal fungi are some examples of bio-fertilizers used to enhance soil fertility and plant growth.
Improved soil fertility and disease resistance are results of using bio fertilizers instead of chemical fertilizers.Specifically, bio fertilizers are nitrogen fixing bacteria and phosphate solubilizing bacteria and fungi. They develop symbiotic relationships that are mutually beneficial to the micro-organisms and plant roots. They release nutrients back slowly enough in the soil that plants have the time to direct them into activities other than growth, such as disease resistance and stress tolerance.

1. Growth of microflora regarding the use of carrier material 2. Structure of the soil before and after the application of bio fertilizers.
Enrich the soil and support the soil food web are uses of bio fertilizers.Specifically, bio fertilizers are made up of nitrogen fixing bacteria and phosphate solubilizing bacteria and fungi. They enrich the soil with nitrogen and phosphorus that are in forms that can be taken in by plant roots. They release their nutrients slowly so plant roots never are overwhelmed by too much fertilizer.
Because Manure provide Humus to the soil while fertilizers do not provide any humus. Fertilizers provide a specific nutrient to the soil while manure is reactively liss rich in plant nutrient.
Azolla is a type of fern that has been around since the time of the Dinosaurs. It is a bio fertilizer that may be used in paddy fields and similar cultivation to avoid harsh chemical fertilizers that destroy the soil.
There are two primary reasons:The bio fertilizer does not have enough nutrients in it to get a good response from the crop. Have the material tested by an independent lab. to find out its true nutrient content.The bio fertilizer was spread too thinly for the nutrient level demanded by the crop. Ensure that the material is spread to the level needed by the crop according to the soil test. Many bio fertilizers, such as as compost, need to be spread as much as six inches thick on the soil surface, then worked into the soil.
