Study Notes
Microbial Roles in Agriculture
- Microbes are crucial for nutrient cycling in soil and maintaining soil fertility.
- They also protect crops.
Soil Fertility Enhancement
- Microbes are used to create biofertilizers.
- New nitrogen-fixing organisms are being developed.
Nitrogen Fixation
- Scientists are using recombinant DNA technology to introduce nitrogen-fixing genes (nif genes) into crop plants like wheat, corn, and rice, to enhance their nitrogen uptake.
Biopesticides
- Microbes (viruses, bacteria, and fungi) are utilized as biopesticides to control insect and nematode pests.
