People are increasingly aware of the link between the trillions of microbes that live within our bodies and human health. Studies have found that a healthy population of bacteria, or a microbiome, in a person can prevent food allergies and even treat depression, according to a story in The Conversation.
Just as in the human body, these types of tiny bugs can play an beneficial role in plant health. Growth-promoting bacteria or fungi can be added to plants or soil in a variety of ways – in seed coats, suspended in water and sprayed on plants or soil, or mixed into mulches that are added to the soil or placed around plant stems.
Study of this microscopic world has been going on for decades but is now attracting more interest from researchers looking for environmentally benign methods to improve agriculture.
