There are several bacteria around the root of the plants which through their activities make nutrients available which were typically inaccessible to plants.
They perform this either by breaking down insoluble nutrients or secreting acidic compounds which lower the pH level of the surrounding area.
For example, the role of bacteria in the phosphorous uptake by plants. Due to its highly reactive nature with Iron, Calcium, and Aluminium, it precipitates and hence becomes inaccessible by the plants.
Some of the growth-promoting microbes (PGPB) convert phosphorous into a form that is readily available for the plants.
Nitrogen fixation – this is probably one of the well-known benefits of PGPB, and that’s for a good reason.
Nitrogen is one nutrient that is hardly accessible to the plants.
However, there is some plant growth promoting microbes that can fix atmospheric nitrogen in the soil; hence making the nutrients readily available.
