Farmers usually use chemical fertilizers to grow their crops, but these can be expensive and may harm the environment. A more efficient and cheaper alternative is the use of specific microorganisms called plant growth-promoting bacteria (PGPB). PGPB help plants absorb more nutrients and produce growth hormones that boost crop production. Using PGPB as biofertilizers can provide the same benefits as chemical fertilizers—without the harmful effects.
