Soil microflora
On the other hand, the activities
of some of the microorganisms are beneficial to each other. For instance organic acids
liberated by fungi, increase in oxygen by the activity of algae, change in soil reaction etc.
favors the activity or bacteria and other organisms in soil.
12. Root Exudates: In the soil where plants are growing the root exudates also affects the
distribution, density and activity of soil microorganism. Root exudates and sloughed off
material of root surfaces provide an abundant source of energy and nutrients and thus directly
or indirectly influence the quality as well as quantity of microorganisms in the rhizosphere
region. Root exudates contain sugars, organic acids, amino acids, sterols, vitamins and other
growth factors which have the profound effect on soil microbes.
