Impact of a bacterial consortium on the soil bacterial community structure and maize (Zea mays L.) cultivation

Abstract Microorganisms are often applied as biofertilizer to crops to stimulate plant growth, increase yields and reduce inorganic N application. The survival and proliferation of these allochthonous microorganisms in soil is a necessary requisite for them to promote plant growth. We applied a ster...
