Fertilizers help in the development of the soil quality of the field by replenishing the necessary nutrients that are required by the plant. Let’s see why Biofertilizers are better than Inorganic Fertilizers (Chemical Fertilizers):-
| Biofertilizers | Inorganic Fertilizers |
|---|---|
| They are part of organic farming, better and sustainable agriculture. | They are not part of sustainable agriculture. |
| They are renewable nutritional resources mostly nitrogen-fixing microbes. | They are traditionally used on a large scale to obtain more crop yield. |
| They are free living and symbiotic bacteria, cyanobacteria, or fungi. | They are in the form of chemicals. |
| They enrich soil with nutrients. It is eco-friendly and not hazardous for our health. | Overutilization of chemical fertilizers causes pollution of soil & it is hazardous for our health. |
| They provide almost all the nutrients, but slowly. | They supply only the specific nutrients, but quickly. |
| Large scale application is possible. | Large scale application is possible but it will be costly. |
| Maintain a natural cycle of soil, build soil, organic matter and enrich soil fertility. | Danger of over fertilization kills plants and degrades the renewable environment; contributing to the greenhouse gas effect. |
| They provide nutrients by natural processes to promote plant growth. | A high concentration of chemicals, nitrogen, phosphorus & potassium is required for plant growth. |
| Plant growth stimulation occurs through the synthesis of nutrient acquisition hormone production and biocontrol. | Plant growth stimulation occurs through the synthesis of inorganic material. |
| Eg:- Rhizobium, Azotobacter, Azospirillum | Eg:- Ammonium nitrate, Ammonium sulfate, Urea, etc. |
