Microbes make nutrients in the soil available to plants in a form the plants can use. Microbes create some of those nutrients, and we (with Natureâs help) add the rest.Because the plants are healthier, they resist disease better, and tolerate environmental stress better.Microbes improve soil structure by the humus they create while digesting organic matter. Microbes help in nitrogen fixing.t is the microbes that convert the NPK and minerals in the soil into a form our plants can use to grow and produce food and flowers for us. Microbes Microbes are everywhere. They are in the air, in the rivers and oceans, in our drinking water, in the soil, and on our skin.
