Title: A review of investigations in soil bacteriology
Description: Soil fertility, broadly interpreted, denotes the crop-producing power of any soil under given climatic conditions, and is itself the resultant of many forces often opposed to one another. It is no easy task to establish the correlation of these several forces, and to assign to each its true position as a factor in the creation of plant substance. We do know that suitable moisture and temperature conditions are indispensable not only for the absorption and assimilation of the plant food in the soil, but also for the formation of this plant food.
