Book excerpt: Excerpt from The Journal of Agricultural Science, 1915-16, Vol. 7 The remarkable relationships existing between the microorganisms of the soil and the growth of plants have given rise to numerous researches on the bacteria, fungi, and more recently the protozoa of the soil, and considerable knowledge has now been obtained of the organisms present in normal soils. The earlier investigations were necessarily confined largely to methods of isolation, descriptions of the organisms found and studies of their behaviour in certain culture solutions, but sufficient of this preliminary work has been done to enable us to attack the real problem and try to Obtain a picture of the life in the soil as it actually is. For this purpose it is necessary to know the relative abundance of the various organisms, to find out which are active and which inert, and to discover what the active forms are doing and what is their mode of life. Before the bacteriological and zoological work can be fully interpreted, however, it is necessary to discover the conditions under which life in the soil goes on, and in the series of papers, of which this is the first, it is proposed to deal with the air supply, water supply, and. Temperature of our own soils. And by comparison with other investigations to see how far the observed relationships hold generally.
