Excerpt from The Micro-Organisms of the SoilThe purpose of this volume is to give the broad outlines of our present knowledge of the relationships Of the population of living organisms in the soil to one another and to the surface vegetation. It is shown that there is a close relationship with vegetation, the soil population being dependent almost entirely on the growing plant for energy material, while the plant is equally dependent on the activities Of the soil population for removing the residues of previous generations of plants and for the continued production in the soil of simple materials, such as nitrates, which are necessary to its growth. It is also shown, however, that the soil population takes toll of the plant nutrients and that some of its members may directly injure the growing plant.About the PublisherForgotten Books publishes hundreds of thousands of rare and classic books.
