Question

how could soil fertility be increased by the microorganism​

Answer 1

• By recycling nutrients including carbon, nitrogen, sulphur, and phosphorus, bacteria improve soil fertility.
• Bacteria breakdown decaying organic materials in the soil, releasing simple molecules that plants may use.
• Nitrogen-fixing bacteria fix nitrogen from the atmosphere and increase the amount of nitrogen in the soil, making it easier for plants to absorb.
• They also raise the soil's water-holding capacity and improve its structure.
