Question

What roles do Rhizobium and blue green algae play in agriculture?

Answer 1

• Rhizobium is a naturally occurring soil bacteria that can form a symbiotic relationship with legume crops.

Basically the bacteria attaches to the roots of the legume, forming nodules, and draws energy from the plant.

Many times the rhizobium produce more nitrogen than its symbiotic partner can use.

The most common nutrient limiting the production of agricultural crops is nitrogen.

• Blue Green Algae (BGA) are alternative source of nitrogen to the chemical fertilizers.

The choice of biological fertilizer is due to eco-friendly, fuel independent, cost effective and easily availability
